CD4024BHSR - 7-Bit Binary Ripple Counter 3-18V | Renesas
The Renesas Electronics CD4024BHSR is a 7-bit binary ripple-carry counter IC with a maximum count rate of 12 MHz, operating from a 3 V to 18 V supply over the full military temperature range of -55C to +125C, supplied in unpackaged die form. The device counts on the negative-going clock edge and provides an asynchronous MASTER RESET input. A binary ripple counter is a digital counter in which the output of each flip-flop stage clocks the next stage, rather than all stages clocking from a common source. Ripple counters sit within the broader hierarchy of sequential logic -> counters/dividers -> logic ICs. Because the carry ripples through seven stages, propagation delays accumulate, which limits the maximum count frequency but yields an extremely simple, low-power, low-pin-count frequency divider architecture. Key features of the CD4024BHSR include the 7-bit counting range (divide-by-2 through divide-by-128), unbuffered monolithic CMOS construction, negative-edge clock triggering, and an asynchronous active-high reset. The wide 3 V to 18 V supply range makes it compatible with legacy CMOS and military power rails, and the -55C to +125C rating supports harsh-environment designs such as avionics and defense systems. Technically, the unbuffered CMOS output structure gives the part reduced switching noise and the ability to operate with very low quiescent power, although unbuffered outputs exhibit higher output impedance than buffered 4000-series equivalents. Each of the seven Q outputs divides the input clock by successive powers of two, enabling cascaded frequency division from a single package. Typical applications include frequency division in clock trees, long-duration timers in industrial controllers, event counting in instrumentation, and ripple-divider chains in military and aerospace electronics where the die-format packaging supports custom hybrid or COB (chip-on-board) assembly. When designing with this part, remember that asynchronous ripple counters produce decode glitches on intermediate states; decode only when the count is settled or use a synchronous counter if glitch-free outputs are required. This page adds information gain beyond the datasheet by consolidating distributor stock data, drop-in same-family alternatives, comparison tables, and practical design notes for the CD4024BHSR in one place.
CD4026BF - 5-Bit Decade Counter | Harris Corporation | Displays
The Harris Corporation CD4026BF is a CMOS decade counter and divider with a 5-bit output, 7-segment display decoder, positive-edge clocking, and a 16-CDIP package. According to the verified distributor data, it operates from 3 V to 18 V and supports operation up to 16 MHz. Its integrated decoder converts the counter's internal Johnson-code output into drive signals for one numerical seven-segment display, reducing the component count required in compact display systems. The CD4026BF is one member of the CD4000 CMOS logic family and is categorized as a counter, divider, and display-interface integrated circuit. A CMOS decade counter is a synchronous digital counter that advances through ten states for each complete decade of input pulses. The CD4026B combines a 5-stage Johnson counter with a seven-segment decoder, while the CD4033B provides a similar counter structure with binary rather than decoded display outputs. Within the broader hierarchy, the CD4026BF is a CMOS logic IC, a counter and divider, and a display-decoding integrated circuit. This integration is especially useful where low power dissipation, compactness, and direct seven-segment drive capability are important. The verified product data identifies a single counter element, 5-bit output organization, positive-edge triggering, and a 16-CDIP package. Its stated 3 V to 18 V supply range permits operation from conventional 5 V and 9 V logic systems as well as 15 V industrial-class supply rails. The stated 16 MHz operating frequency provides substantial counting headroom for digital clocks, timers, counters, sequencing circuits, and instrumentation. A qualified power design must still preserve the supply limits and respect the timing requirements of the connected logic family. The CD4026BF includes clock, clock-inhibit, reset, carry-in, carry-out, decoded display, and supply connections. Its decoded outputs are intended for one seven-segment numerical display rather than arbitrary seven-segment patterns. Carry-in and carry-out support decimal chaining, allowing multiple counting stages to represent values beyond a single decade. The external clock can be inhibited when required, while reset provides a defined starting state. Exact pin functions and electrical limits should be confirmed against the manufacturer datasheet before layout or production release. Typical uses include digital frequency meters, event counters, industrial panel displays, timer terminals, laboratory instruments, and compact decade-counting modules. In a seven-segment display application, the device can replace separate counter and decoder ICs, simplifying the board area and reducing interstage wiring. In cascaded decimal applications, carry-out can drive the next counter while carry-in determines the selected decade. Designers should account for display current, segment resistors, and the electrical loading of any additional logic connected to the decoded outputs. A critical design consideration is decoupling. Place the required supply-bypass capacitor close to the 16-CDIP power and ground pins, minimize the clock path between the oscillator or signal source and the clock input, and route return currents without sharing narrow paths with display-current returns. The CD4026BF is a digital counter rather than a power semiconductor, so a safe operating area specification is not applicable. Component marking, ceramic or hermetic grade, temperature grade, and sourcing conditions should be verified against the approved manufacturer documentation. This page consolidates the verified distributor specifications, package information, cross-reference evidence, practical application guidance, and honest replacement analysis for the CD4026BF. It also distinguishes electrically similar counter options from genuinely verified drop-in choices, helping engineers avoid assuming that same-family CMOS logic parts are interchangeable without checking pinout, supply voltage, display outputs, temperature grade, and package construction.
CD4028BF - CMOS BCD-to-Decimal Decoder | Texas Instruments
The Texas Instruments CD4028BF is a CMOS BCD-to-decimal or binary-to-octal decoder/driver housed in a 16-pin ceramic DIP (CDIP, J) package rated for the military -55C to +125C operating range. It accepts a 4-bit BCD input and asserts one of ten active-HIGH decoded outputs, with three additional binary-to-octal outputs for codes 10-15. Each input is buffered and the device operates across 3V to 18V supply with parametric ratings at 5V, 10V, and 15V. A BCD-to-decimal decoder is a combinational logic circuit in the CMOS 4000-series family that converts Binary Coded Decimal input codes (0000-1001) into one-of-ten mutually-exclusive active-high outputs. As a member of the decoder/driver category within the broader integrated circuit hierarchy (decoder/driver -> decoder -> logic IC -> semiconductor), it sits alongside address decoders, display drivers, and code converters, providing 1-of-10 fan-out with on-chip input buffering for direct drive of indicator tubes, Nixie displays, and memory-chip select lines. Key features of the CD4028BF include 4 buffered inputs with standard CMOS B-series noise immunity, 10 decoded outputs that are mutually exclusive (only one HIGH at a time), 3 additional outputs Y2/Y4/Y8 that decode the binary-to-octal function for codes 10-15, and quiescent current of approximately 0.5 uA at 5V VDD. The CDIP-16 ceramic package provides hermetic sealing for military and aerospace programs requiring extended reliability under thermal and mechanical stress. Per the TI CD4028B-MIL product page, the part meets all requirements of JEDEC Tentative Standard No. 13B for B-Series CMOS Devices. The CD4028BF is built on a 4000B-series CMOS process with P-channel and N-channel enhancement MOSFETs implementing the NAND/NOR decode matrix, followed by output buffers sized to source/sink approximately 1 mA at 5V VDD. The buffered inputs prevent input loading on the driving logic, allowing direct connection to standard TTL or CMOS sources even when VDD exceeds Vih(TTL). The decoded outputs are non-latching and follow the input code in real time, which simplifies memory-chip-select decoding where a static address must be continuously asserted. Typical applications include indicator-tube (Nixie) drivers for vintage instrumentation displays, memory-chip select decoding for systems requiring more than four chip enables, address decoding for I/O expansion, decimal readout for digital meters, and code conversion from BCD/binary to one-hot representations. The wide 3V to 18V supply range supports both 5V TTL and 15V CMOS system environments without level shifters. When designing with the CD4028BF, ensure VDD decoupling with a 0.1 uF ceramic capacitor placed close to pin 16 (VDD), tie unused inputs to VDD or GND to prevent shoot-through current, and verify that output sink/source current stays within the 1 mA limit when driving high-current loads such as Nixie cathodes - in those cases add a discrete transistor buffer stage. This page synthesizes distributor pricing, MIL-spec drop-in alternatives, pinout reference data, and PCB design notes not found in the bare datasheet, enabling engineers to source, qualify, and lay out the CD4028BF faster.
CD4033BD - 5-Bit CMOS Decade Counter | Texas Instruments
Texas Instruments CD4033BD is a CMOS decade counter with five decoded decade outputs, operating from a 5 V supply with a 700 ns propagation delay in a 16-CDIP through-hole package. It is designed for digital counting, frequency division, timing, and display-control applications where a ripple-decade counter is required. A decade counter is a sequential digital-logic component that counts ten states, from zero through nine, and provides decoded outputs for each count. The CD4033BD belongs to the CD4000 CMOS logic family, a subgroup of counter and divider ICs within logic ICs, digital counters, and broader semiconductor products. Its ten decoded output lines allow a display or control system to respond directly to the current count without external binary-to-decimal decoding. Key features include a 5-bit counter section, 16-pin DIP-compatible construction, through-hole mounting, and a stated operating temperature range of -55 °C to 125 °C. The verified product data identifies the CD4033BD as a positive-edge, decade counter with one counter element, a 700 ns propagation delay, and operation from a 5 V supply. The military-temperature grade makes it suitable for equipment requiring an extended temperature range. The CD4033BD is a synchronous CMOS counter with decoded decade outputs. The CLK input advances the count on the positive edge, while the reset and clock-control inputs provide basic sequencing control. Its CMOS architecture supports low-power operation in suitable systems and provides a direct interface to decade-oriented displays, counters, and industrial timing circuits. Typical applications include decade frequency dividers, digital frequency counters, switch-debounce and event-counting systems, display sequencing, industrial panel timers, and embedded timing modules. The decoded Q outputs are especially useful when a design needs ten mutually exclusive output states rather than a binary word. Designers should verify the exact voltage limits, input timing, output-drive capability, and reset behavior against the manufacturer datasheet before using it as a direct substitute in a new circuit. The through-hole package simplifies prototyping and repair, but modern compact products may require a surface-mount counterpart rather than the DIP package. This page consolidates verified distributor pricing, package and timing information, functional application guidance, and pin-level implementation notes so engineers can evaluate the CD4033BD for counter and decade-decoder designs without relying on a single product listing.
CD4033BE - Decoded CMOS Decade Counter | Texas Instruments
The Texas Instruments CD4033BE is a CMOS decade counter/divider with decoded 7-segment display outputs, ripple blanking, and lamp-test functions in a 16-pin PDIP package. It combines a 5-stage Johnson decade counter with an output decoder for driving one stage of a numerical display. According to the manufacturer data, its fully static counter operation extends from DC to 6 MHz typically at VPP = 10 V. The part uses a positive-edge clock and provides a 5-bit counter with decoded display outputs, making it suitable for low-power display and counting systems. A decade counter is a sequential logic device that advances through ten states and then returns to zero. The CD4033BE belongs to the CMOS logic family, whose low static power and broad supply-voltage operating capability are useful in battery-powered and low-power display equipment. Its decoded outputs reduce the external logic count required to translate counter state into the a-through-g segment signals needed by a common-cathode seven-segment display. The chip therefore combines counter, divider, and display-interface functions in one package. Key features include counter and 7-segment decoding in one package, easy interfacing with common seven-segment display types, fully static counter operation from DC to 6 MHz typically at VPP = 10 V, and low-power operation suited to display equipment. A display-enable output provides control over the decoded segment outputs. Ripple blanking is intended to suppress undesirable display transitions, while the lamp-test function supports display testing. These features reduce external component count and simplify compact counter modules. Technically, the device uses a 5-stage Johnson counter followed by a decoder that converts the counter state into seven segment outputs. The decoded interface is designed for one numerical display stage, so a multidigit display generally requires additional counters and appropriate inter-digit blanking arrangements. The manufacturer identifies the device as a CMOS decade counter/divider, and distributor listings describe it as a one-element, 5-bit, positive-edge counter. Detailed operating-voltage limits, output-drive ratings, input leakage, and timing tolerances were not included in the supplied source data and therefore require confirmation in the manufacturer datasheet. Typical uses include standalone decimal counters, laboratory timing references, educational counter trainers, appliance control panels, pulse-counting displays, and compact digital instruments. In a pulse-counter display, the CLOCK input receives the event signal, RESET returns the count to zero, and the decoded outputs drive the segment driver stage. The integrated lamp-test and ripple-blanking functions are particularly useful when operators need to identify failed display segments or avoid visible flicker during counting transitions. When laying out a CD4033BE circuit, account for CMOS input behavior, unused-input handling, supply decoupling, and display-current limits. Because the supplied evidence does not provide complete electrical tables or a verified pin-by-pin diagram, engineers should confirm pin connectivity, maximum supply voltage, output current, clock edge behavior, and timing limits against the official Texas Instruments CD4033B documentation before fabrication. This page consolidates the verified manufacturer description, distributor identification, pricing reference, package information, application guidance, and drop-in-replacement constraints for CD4033BE. It also distinguishes documented characteristics from parameters that still require direct datasheet confirmation, avoiding unsupported precision where the retrieved data is incomplete.
CD4049AE - Hex CMOS Buffer/Converter, 3-18V | Harris
The Harris CD4049AE is a hex inverting/non-inverting CMOS buffer and logic-level converter with a 3 V to 18 V supply operating range, supplied in a 16-pin DIP package. The device provides six independent buffer channels for converting or restoring logic levels and can operate from the same supply used by the associated CMOS logic. According to the manufacturer information referenced by the distributor listing, the CD4049 family is intended for buffering and logic conversion applications. A CMOS buffer or converter is a logic IC that isolates a source from a driven load while providing compatible voltage levels. In the device hierarchy, CD4049AE belongs to the CMOS logic family, with the broader categories of digital logic, integrated circuit, and semiconductor. Its wide supply-voltage range allows use in systems operating from low-voltage 3 V rails through traditional 18 V CMOS rails, although operating points must remain within the limits stated in the manufacturer datasheet. The CD4049AE is described as a hex inverting/non-inverting buffer converter. Its primary advantages are flexible supply-voltage operation and the availability of multiple channels in one package. Because the AE package is a through-hole 16-pin DIP, it is appropriate for legacy industrial equipment, prototypes, repair assemblies, and control systems where surface-mount components would require a different physical footprint. The CD4049 family is frequently considered when a logic signal must drive another circuit with a different input voltage requirement or when a signal source needs buffering. Input and output rise and fall times, propagation delay, output drive current, input leakage, and noise margins must be checked against the actual clock rate, load capacitance, supply voltage, and logic thresholds of the connected devices. The CD4049AE should not automatically be treated as a general-purpose level shifter for every interface. Typical uses include industrial control logic, legacy instrumentation, display and interface control, signal conditioning between CMOS stages, and repair of systems originally designed around the CD4000 family. In these applications, the six buffered channels can reduce loading on sensitive logic outputs while maintaining compatible supply-domain operation. When designing around the CD4049AE, begin with the manufacturer datasheet and confirm the exact pinout, input/output logic behavior, absolute maximum ratings, and timing limits for the relevant revision. Check that every connected signal remains within the permitted input-voltage range, that unused inputs are tied to a defined logic level, and that unused outputs are left unconnected unless the datasheet permits otherwise. Supply bypassing and breadboard or PCB layout quality also matter because long connections and high-impedance nodes can increase noise susceptibility and transition-time distortion. This page combines verified distributor sourcing information, the referenced CD4049 family description, package details, structured engineering guidance, and clearly marked data gaps. It is intended to help engineers identify the CD4049AE quickly while separating confirmed facts from parameters that must be obtained from the official manufacturer datasheet before design release.
CD4049AK - Hex Non-Inverting Buffer, 12V, 16-CFP | Harris
The Harris Corporation CD4049AK is a 12 V hex non-inverting buffer integrated circuit offered in a 16-CFP surface-mount package. The verified distributor listing identifies the device as an active logic buffer/channel element, while the CD4049 family documentation identifies the CD4049 series as a hexadecimal non-inverting buffer. Its 16-CFP package provides a compact surface-mount option for designs requiring buffered CMOS logic rather than a direct gate-to-gate connection. A non-inverting buffer is a digital logic device that reproduces its input at the corresponding output without changing the logical polarity. Within the broader semiconductor hierarchy, the CD4049AK belongs to CMOS logic ICs, specifically the buffer and inverter category. A buffer can add drive strength and isolate a logic stage from downstream loading, provided its voltage, timing, and drive specifications remain acceptable for the intended circuit. The key verified attributes of the CD4049AK are its 12 V supply designation, non-inverting buffer function, hexadecimal organization, 16-CFP surface-mount package, and active lifecycle status. The Harris designation preserves compatibility with established CD4000-series sourcing. Rochester Electronics is the distributor associated with the exact CD4049AK listing on DigiKey, while other verified listings also connect the MPN with Harris and the 16-CFP package. CD4000-series logic is commonly evaluated for industrial control, interface isolation, signal conditioning, and embedded digital systems. The CD4049AK should be selected only after confirming its complete electrical limits, input and output logic levels, propagation delay, output drive, noise margin, and power dissipation from the applicable manufacturer datasheet. The same package outline must also be checked against the PCB land pattern before it is treated as a direct replacement. Typical design roles include buffering digital control signals, driving logic inputs away from a source device, distributing a logic signal to multiple compatible loads, and separating a high-impedance logic node from downstream switching or fanout requirements. In each case, the input must remain within the accepted logic range and the connected load must not exceed verified output-current and capacitance limits. The most important layout consideration is to minimize trace length between the buffer and its driven load while maintaining a stable ground reference. Unused inputs should not be left floating if the manufacturer datasheet specifies a defined state. Supply bypassing, input thresholds, and maximum supply voltage must also be checked before publication of the PCB design. This page consolidates the verified distributor price, stock indication, manufacturer identity, package information, lifecycle state, and available cross-reference findings for CD4049AK. It also distinguishes confirmed drop-in alternatives from unverified or different-package substitutes so engineers can avoid unsupported replacement claims.
CD4050BD - Hex Non-Inverting CMOS Buffer, 3-18V, 16-SOIC | Texas Instruments
The Texas Instruments CD4050BD is a hex non-inverting buffer (buffer/converter) in a 16-pin SOIC package, providing six independent push-pull CMOS output stages that operate from a single 3 V to 18 V supply. What is a hex non-inverting buffer? A buffer is a logic IC that reproduces the logic level of its input at its output without inversion, adding gain and drive strength rather than changing the boolean function. The CD4050 belongs to the RCA CD4000 CMOS logic family, whose defining characteristic is wide supply-voltage tolerance from 3 V up to 18 V, allowing one device to interface 3.3 V, 5 V, 9 V and 15 V CMOS domains. Within the logic hierarchy, CD4050 is a buffer/converter (line driver) rather than a gate, and the six-element arrangement makes it a hex part. Key features include six non-inverting channels, push-pull output stages that source and sink current symmetrically, and single-supply operation that also permits input levels above VCC for level conversion. Because the outputs are push-pull rather than open-drain, no external pull-up resistors are required and the part drives capacitive bus loads directly. The 16-SOIC (0.154 inch, 3.90 mm width) surface-mount package is a legacy-standard footprint still widely supported by assembly houses and compatible with automated pick-and-place lines. Technically the part uses complementary CMOS (CMOS) construction, giving high noise immunity and low static power consumption across the supply range. Because it is a converter-class device, input thresholds track the supply rails rather than being fixed to a single logic standard, which is the mechanism that makes single-supply level shifting possible. Its main limitation versus modern rail-to-rail buffers is speed: the CD4000-family propagation delay is on the order of tens of nanoseconds, far slower than CMOS logic buffers such as the 74HC04 class. Typical uses include buffering long TTL or CMOS bus lines, level translation between 3.3 V, 5 V and higher-voltage CMOS domains, driving heavier loads than a plain gate can handle, and isolating control signals in industrial, instrumentation and legacy 4000-series designs where mixed-voltage CMOS logic still appears. A key design consideration is that CD4000-family parts draw supply current that rises with switching frequency, so the supply rail must be able to absorb dynamic current while maintaining a stable ground reference; a 0.1 uF bypass capacitor close to pin 14 is standard practice. Because this is a mature, cost-optimized part, designers migrating to 74HC/74HCT logic should re-check timing margins and input-level compatibility rather than assuming interchangeability. This page consolidates distributor pricing, same-footprint drop-in alternatives and practical layout guidance that are not collected in any single manufacturer document, giving engineers a single reference before committing to the CD4050BD on a new board.
CD4050BE - 6-Channel CMOS Buffer | Texas Instruments
The Texas Instruments CD4050BE is a six-element, non-inverting CMOS buffer and logic-level converter with one bit per element and push-pull outputs, packaged in a 16-pin PDIP. Its verified operating supply range is 3 V to 18 V, allowing the same device family to buffer or shift signals between different logic voltage domains using one supply voltage. A CMOS buffer is a digital logic device that reproduces its input signal at the output while providing buffering and, in this case, non-inverting logic-level conversion. Within the product hierarchy, the CD4050BE is a six-channel buffer, part of the CD4000 CMOS logic series and the broader logic IC category. Unlike an inverting buffer, each of its six channels preserves the input logic state. The six-channel architecture allows one package to serve several independent signal paths. Push-pull outputs provide a defined output state and make the device suitable for driving downstream CMOS inputs. Logic-level conversion can bridge signals whose voltage levels differ when the input and output thresholds remain compatible with the selected supply voltage. The CD4050B family uses a single positive supply, and the verified product information identifies a 3 V to 18 V operating range. This broad range supports integration across legacy 5 V systems and higher-voltage CMOS logic where the input and output signal levels are compatible with the device thresholds. Exact propagation delay, output-current, and input-threshold values were not included in the supplied verified data and therefore are not asserted here. Typical uses include interfacing signals between different logic-voltage domains, buffering multiple digital control lines, and driving CMOS inputs from sources operating at a different logic level. The device can also provide multiple non-inverting channels in logic circuits where inversion would be undesirable. Because each channel is independent, unused channels should be tied to a defined logic state according to the manufacturer recommendations. The main design consideration is ensuring that every connected signal remains within the input and output limits of the selected 3 V to 18 V supply. Designers should also account for unused inputs, supply decoupling, output loading, and the maximum transition rates verified in the manufacturer datasheet. The through-hole PDIP package is intended for conventional through-hole PCB assembly rather than surface-mount production. This page consolidates the verified manufacturer and distributor information for CD4050BE, adds same-package cross-reference options, and provides practical guidance for logic-level conversion, unused inputs, decoupling, and component selection. It also distinguishes confirmed characteristics from parameters that require consultation of the manufacturer datasheet before design release.
CD4050BF - 6-Channel CMOS Buffer, 3-18 V | Texas Instruments
The Texas Instruments CD4050BF is a 6-channel, non-inverting CMOS hex buffer and logic-level converter operating from 3 V to 18 V. The device is supplied in a 16-pin ceramic dual in-line package, and its specified temperature range is -55 °C to 125 °C. Each buffer provides a non-inverting output path, allowing the part to support buffering and single-supply level translation between compatible CMOS voltage domains. A CMOS hex buffer is a digital logic device that receives six input signals and presents six buffered, non-inverting outputs. Buffers separate a source from its load, improve signal integrity, and can isolate logic levels when the input and output use different voltage references within the device operating range. In the CD4000 family hierarchy, the CD4050BF belongs to CMOS logic ICs and is commonly used as a line driver or logic-level converter. The verified feature set includes six buffered channels, single-supply operation from 3 V to 18 V, non-inverting logic, and a military temperature range of -55 °C to 125 °C. Because it uses one supply voltage, the CD4050BF avoids the separate positive and negative reference rails historically associated with TTL-to-CMOS interface designs. This makes it useful where the source and destination circuits operate from the same supply but still benefit from output buffering. The CD4050BF is based on the CD4050B family architecture and is intended for digital buffering rather than analog amplification. Its CMOS inputs provide high input impedance and minimize loading of the upstream device. Each output stage restores logic levels, helping maintain usable rise and fall times when driving additional CMOS inputs or cable capacitance. Typical applications include industrial control and instrumentation, data acquisition, test equipment, legacy interface isolation, clock or signal distribution, and level translation within a 3 V to 18 V system. In instrumentation, the six channels can buffer sensor-conditioning outputs before they enter an ADC or counter. In control systems, the part can distribute buffered digital state signals among multiple receiver sections. When designing around the CD4050BF, keep every connected signal within the specified input and output voltage limits, and do not exceed the 18 V maximum supply voltage. Decoupling close to the supply pins remains necessary for a CMOS device switching capacitive loads. Because the verified data does not provide a complete electrical characteristic table, propagation delay, output drive current, input leakage current, and logic-level thresholds should be confirmed in the manufacturer datasheet before release. This page consolidates manufacturer and distributor references, validated CD4000-family equivalents, package-aware comparisons, and practical application guidance. It also identifies where the available sources do not publish a value, preventing unverified electrical specifications from being presented as guaranteed production data.
CD4050BK - 18V CMOS Hex Buffer | Harris Corporation
Harris Corporation CD4050BK is a non-inverting, six-element CMOS buffer and level converter with a maximum supply voltage of 18 V, packaged in a 16-CFP configuration. The device provides six independent one-bit channels and uses push-pull outputs according to the CD4050 family documentation. Its principal role is buffering compatible CMOS signals while supporting logic-level conversion with a single power supply. A CMOS buffer is a digital logic device that reproduces its input signal at an output with added drive strength. The CD4050 belongs to the CD4000 CMOS logic family, which sits within the broader digital IC and logic IC hierarchy. Unlike open-collector buffers, these devices use push-pull outputs, allowing them to source and sink output current without requiring an external pull-up resistor. The verified CD4050 family information identifies six non-inverting channels, one output bit per element, 3 V to 18 V operation, and an 18 V maximum supply rating. CMOS construction supports low static power relative to many older bipolar logic families. The buffered outputs are intended to improve signal integrity when driving downstream logic or interconnect, while the single-supply level-conversion capability can bridge compatible systems operating at different logic thresholds. The CD4050B family is based on complementary MOS circuitry using N-channel and P-channel enhancement-mode transistors. Separate input and output behavior should be checked against the relevant datasheet before finalizing edge-rate, fan-out, and loading calculations. The supplied source set confirms the CD4050B family's three-rail logic-level-conversion function and 3 V to 18 V supply range, but it does not provide a complete timing table, output-current rating, or absolute maximum ratings for the Harris CD4050BK. Typical uses include buffering digital control signals, interfacing compatible CMOS logic domains, clock distribution, and driving multiple standard CMOS loads. The non-inverting topology preserves signal polarity, while six independent channels make the device useful when more than one buffered logic path is required. Board-level applications should avoid using the CD4050BK for high-speed differential signals, high-voltage isolated interfaces, or loads exceeding the verified output-current capability. A key design consideration is that buffered CMOS outputs still have finite rise and fall times. Long PCB traces, capacitive inputs, stacked supply pins, and high fan-out can slow edges and create timing-margin risk. Decoupling capacitors should be placed close to the supply pins, while unused inputs must be connected to a defined logic level. Exact capacitor values, drive-current limits, and timing thresholds require the missing manufacturer data. This page consolidates the verified distributor identity, package description, CD4050B family supply range, logic function, cross-reference results, and practical design constraints. It also distinguishes verified facts from unavailable electrical details rather than estimating pinout, timing, thermal, or lifecycle values that are not present in the supplied sources.
CD4050BNSR - Hex Non-Inverting Buffer 3-18V SOP-16 | TI
The Texas Instruments CD4050BNSR is a CMOS hex non-inverting buffer and logic-level converter that operates from 3V to 18V, packaged in a 16-pin Small-Outline (SOP / NS) tape-and-reel format. Each of the six buffers accepts a standard CMOS input and drives a push-pull CMOS output, with input clamp diodes on every input pin to allow safe translation from voltages above VCC (up to 18V) down to the single VCC rail used by the device. A CMOS buffer/converter is a digital logic building block whose primary job is to provide current drive gain and voltage-level translation between two logic domains without inverting the signal. Within the broader hierarchy of ICs, the CD4050B belongs to the CD4000 family of CMOS logic ICs, which sits under the Specialty Logic / Buffers & Line Drivers segment of the Logic IC category. Each buffer in this part functions as a stand-alone driver channel that sources and sinks current into the next stage, isolating the input logic domain from the load. The 'B' suffix denotes the buffered TI/CMOS output stage that improves noise margin over the older unbuffered CD4050A. Key features include 6 independent channels, push-pull CMOS output drive, very low quiescent supply current (typically in the microamp range), input clamp diodes that protect the input from voltages up to 18V regardless of VCC, and a propagation delay of approximately 50 ns at 10V VCC (Standard speed). The 16-pin SOP (NS) package measures 0.209 inch (5.30 mm) body width, making it compatible with industry SOP-16 footprints and conventional lead-free reflow profiles. The CD4050B uses a complementary MOS enhancement-mode P-channel and N-channel transistor output structure in every channel, which provides symmetrical rise/fall drive and low quiescent leakage. The single-supply VCC architecture means only one rail is required, while the input clamp diodes perform the level-shift work by clamping input voltages above VCC down to a diode drop above VCC. The push-pull output stage delivers rail-to-rail output swings while preventing shoot-through, unlike the older CD4049UB which provides inverting buffers with the same drive. Typical applications include CMOS-to-DTL/TTL logic-level translation in mixed-voltage systems, signal buffering between high-impedance sensor outputs and downstream CMOS logic, input protection/level-shifting for buttons and switch contacts, and bus buffering where a non-inverting driver must preserve the original logic state. The wide 3V to 18V supply tolerance makes it compatible with 3.3V, 5V, 9V, 12V, and 15V logic rails. When designing with this part, note that unused inputs must be tied to VCC or GND - they MUST NOT be left floating, because floating CMOS inputs draw quiescent current and can drift into the linear region. The input voltage, thanks to the clamp diode, may safely exceed VCC (up to 18V) for logic-down translation, which is the opposite of the more common step-up translation. The push-pull outputs can drive standard CMOS loads and modest TTL loads through an external pull-up resistor. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the standalone TI datasheet, including an explicit pin-for-pin comparison versus competing CD4050B equivalents from onsemi, Toshiba, and ROHM in the same 16-SOIC footprint.

Texas Instruments CD4051B is a 20 V, 8:1, single-channel CMOS analog multiplexer with three binary select inputs, an inhibit input, and logic-level conversion. It connects one of eight input channels to a common output, making it suitable for analog signal routing, instrumentation, measurement, control, and embedded systems. The verified product-page description identifies the device as a single-channel analog multiplexer, while the manufacturer datasheet confirms the three A, B, and C selection inputs and inhibit control. An analog multiplexer is a routing component in the signal-chain hierarchy that selects one source signal and connects it to a shared output. The CD4051B belongs to the CMOS analog-switch and multiplexer family, with logic-level conversion allowing its control inputs to interface with systems operating across compatible logic levels. Its eight-channel architecture reduces the number of external connections and is useful when a design must route multiple sensor, measurement, or control signals through one processing channel. The CD4051B provides three binary control inputs, A, B, and C, which select one of eight channels, plus an inhibit input that can disable the selected connection. The device supports operation from the verified 20 V supply rating context. Its CMOS construction is appropriate for low-power and medium-voltage analog routing systems, while the multiplexed output reduces the number of analog inputs required by downstream converters or signal-processing components. Typical uses include sensor-channel selection, instrumentation signal routing, test-equipment multiplexing, industrial control interfaces, and embedded measurement systems. The manufacturer datasheet should be consulted for the exact electrical limits, switching characteristics, control truth table, package variants, and recommended operating conditions before final circuit design. A key design consideration is ensuring that signal amplitudes remain within the device's specified analog and logic ranges. The selected channel, inhibit state, supply sequencing, and input impedance of the downstream circuit must be evaluated together. In systems with high source impedance, leakage, charge injection, switching transients, and settling time can affect measurement accuracy. This product page combines the verified Texas Instruments product and datasheet references with practical selection context. The information gain is the separation between verified device identity, routing architecture, and engineering checks that should be completed before using CD4051B as a drop-in or design alternative.
CD4051BM - 8:1 CMOS Analog Multiplexer | Texas Instruments
The Texas Instruments CD4051BM is a single 8-channel CMOS analog multiplexer or demultiplexer with logic-level conversion, 8:1 signal routing, 240 ohm on-state resistance, and a 16-pin SOIC package. The verified distributor listing identifies it as a 1-circuit IC switch, while the manufacturer documentation describes the CD405xB CMOS analog switching family. Its three select inputs route one common terminal to any one of eight signal channels, making it useful for analog measurement, instrumentation, data acquisition, test systems, and embedded control. An analog multiplexer is a switch matrix that connects multiple inputs to a shared output, or conversely distributes one source across selected destinations. The demultiplexer function is selected electrically by connecting the appropriate terminals. In the broader semiconductor hierarchy, the CD4051BM belongs to CMOS logic ICs, analog switch ICs, multiplexers, and power-management-independent signal-routing components. Unlike a mechanical relay, it provides compact, logic-controlled channel selection, although its on-resistance and capacitance can affect signal fidelity. The CD4051BM includes logic-level conversion, allowing the select inputs to be driven by compatible CMOS logic while the analog signal terminals operate within the device's specified supply and signal limits. Verified distributor data specifically lists the MPN as a 240 ohm, 8:1, single-circuit analog switch in a 16-SOIC package. Exact voltage, current, leakage, propagation-delay, bandwidth, and temperature values were not supplied in the verified dataset and are therefore marked as data needed rather than inferred. The device is useful when a microcontroller must inspect several sensors, select one measurement path, route a reference signal, or connect an external test point to a shared converter. Selection logic determines the active channel, while the common terminal carries the selected signal. Engineers should account for on-resistance, off leakage, charge injection, supply decoupling, input voltage limits, and the package pinout before using it in precision or high-speed systems. Typical uses include 8-channel sensor scanning, laboratory and industrial data acquisition, programmable instrumentation, audio or communications routing, and embedded measurement systems. The SOIC-16 footprint is convenient for conventional PCB assembly, but the exact pin names and electrical ratings must be confirmed from the manufacturer datasheet before layout or replacement work. This page combines verified manufacturer and distributor references with practical selection and sourcing guidance rather than assuming unprovided electrical values. The primary design consideration is signal integrity: the selected channel's on-resistance and parasitic capacitance can form an RC network with the driven source and receiving circuit. Keep routing short, provide the required bypass capacitance, respect the logic levels, and verify analog input limits. For a replacement, use the same-package pinout and compare supply voltage, channel count, logic compatibility, on-resistance, leakage, and signal range before substitution. This data page consolidates the verified CD4051BM identity, package, distributor classification, manufacturer datasheet link, sourcing context, and engineering guidance. It does not infer unavailable ratings or claim that a component is available unless the supplied distributor data explicitly indicates purchase or inventory status.
CD4052BE - 4:1 Dual CMOS Analog Multiplexer | Texas Instruments
The Texas Instruments CD4052BE is a 20 V dual CMOS analog multiplexer and demultiplexer with two independently addressed 4:1 channels, a typical on-resistance of 240 ohm, and a 16-pin PDIP package. Its address inputs support logic-level conversion, while the wide 3 V to 20 V supply range accommodates both digital and analog signal routing. The CD4052BE belongs to the CMOS 4000-series logic family and is commonly used to route multiple analog signals through shared converters, amplifiers, instrumentation, or control inputs. An analog multiplexer is an analog switch that connects one of several inputs to a common output according to digital control signals. In the CD4052BE, two multiplexer channels operate in parallel, providing simultaneous routing for paired signals. This makes it useful for differential measurements, stereo or balanced signal paths, and systems that need to select two related inputs without using two separate multiplexer packages. Its logic-level conversion feature allows the address inputs to be driven from a supply range different from the analog signal and main supply conditions supported by the device family. Key features include a dual 4:1 configuration, low typical on-resistance, low off leakage current, binary address decoding, and operation across a 20 V maximum supply. The manufacturer describes the CD4052B as supporting wide digital and analog signal levels, with digital operation identified from 3 V to 20 V in the supplied technical summaries. The 16-pin PDIP package supports through-hole PCB assembly and is identified by distributor listings as a 16-PDIP part. The device is designed for analog signal multiplexing rather than high-speed digital switching. Its performance depends on supply voltage, signal amplitude, control timing, and the impedance of the connected circuit. The multiplexed path introduces on-resistance and capacitance, while off-channel leakage can influence high-impedance measurements. Engineers should therefore account for source and load impedance, settling time, control-logic levels, and analog signal range when selecting the device. Typical applications include routing sensor outputs into an analog-to-digital converter, selecting audio or measurement channels, multiplexing instrumentation inputs, and sharing amplifiers or converters across several sources. It is also suitable for educational and prototype boards where a through-hole dual analog multiplexer simplifies wiring. For reliable layouts, keep the analog signal traces short, connect the supply decoupling capacitor close to the device, route address inputs away from sensitive analog paths, and verify that unused channel and control pins are connected according to the manufacturer datasheet. Do not treat the nominal 4:1 topology as a substitute for checking voltage, current, leakage, and timing limits for the specific signal. This page combines the supplied Texas Instruments product information, distributor descriptions, and verified cross-reference material to provide application guidance, procurement context, and design cautions. It does not add unverified electrical values or assume that every similarly named part is pin-compatible.
CD4052BF - Dual 4-Channel CMOS Analog Multiplexer | TI
The Texas Instruments CD4052BF is a dual 4-channel CMOS analog multiplexer or demultiplexer with logic-level conversion, supplied in a 16-CDIP package. The device provides two independently controlled analog switches that can route paired signal paths for multiplexing or demultiplexing applications. Verified search data identifies the part as a CMOS differential 4-channel analog multiplexer/demultiplexer and specifies an operating temperature range of -55 °C to 125 °C. The control inputs use logic-level conversion, allowing digital control signals to operate across compatible supply conditions described by the manufacturer documentation. An analog multiplexer is a digitally controlled switch that connects one of several analog terminals to a common terminal. A demultiplexer reverses this direction by connecting one common signal path to a selected output. The CD4052 family provides two such channels, making it suitable for routing differential signals, paired sensor outputs, sampled analog inputs, and control signals in test equipment. Its CMOS implementation is intended for low-power logic systems and low-voltage analog-signal switching. The verified CD4052BF datasheet search result identifies a 16-CDIP package and a -55 °C to 125 °C temperature range. The family documentation also describes low ON impedance and very low OFF leakage current. These characteristics help preserve signal integrity when the device switches analog nodes. The logic-level conversion feature is useful when the control logic operates from a supply different from the analog-signal supply. The CD4052BF can be used in data acquisition, instrumentation, communications, embedded control, and analog signal-routing systems. It can select one of multiple input channels into a shared signal path, or distribute one signal path among multiple destinations. The differential two-channel arrangement is particularly useful for systems that carry two related signals, such as complementary sensor outputs or paired communication lines. Designers should verify the exact pin functions, control truth table, allowed supply combinations, input and output voltage limits, and switch timing from the manufacturer datasheet before layout. Because the available verified results do not provide complete electrical tables, missing values are explicitly marked in the specification section rather than estimated. Decoupling, control-signal timing, unused-channel termination, and analog signal-range checks remain important implementation considerations. This page combines verified distributor and manufacturer-linked results with structured application guidance and a conservative replacement assessment. Pricing, lifecycle status, electrical limits, and complete pin-level details should be reconfirmed against the current manufacturer documentation before production release.
CD4052BM - 20V 4:1 2-Channel Analog Multiplexer | TI
The Texas Instruments CD4052BM is a 20 V, 4:1, two-channel CMOS analog multiplexer with logic-level conversion, packaged in a 16-pin SOIC. It connects one of four differential analog input pairs to two outputs, allowing shared access to multiple signals while reducing the number of external connections. The verified distributor listing identifies the device as a two-circuit 4:1 analog switch with 240 ohm on-resistance and a 16-pin SOIC package. An analog multiplexer is a switching IC that routes one selected input channel to an output, or distributes one output signal among selectable inputs. In a demultiplexer arrangement, the same primitive can connect one source to one of several destinations. The CD4052BM uses A and B select inputs together with an inhibit input to control the selected channel, while logic-level conversion helps bridge different supply domains. The key verified feature set includes a 20 V maximum supply rating, dual four-channel analog multiplexing, logic-level conversion, 240 ohm on-resistance, and a 16-SOIC package. These characteristics make the device useful for analog signal routing, test and measurement systems, data acquisition, control systems, and embedded signal-conditioning boards. The multiplexer's purpose is not signal amplification; external buffers, protection, or signal conditioning may still be required. The CMOS architecture is suited to low-power control and analog routing systems, but the exact switching speed, leakage current, channel capacitance, input voltage limits, and operating temperature range were not included in the supplied verified data. Those values should be checked in the manufacturer datasheet before final design release, especially when switching high-frequency, high-impedance, or precision signals. The listed 240 ohm on-resistance is a distributor description and should not be treated as a substitute for the complete datasheet electrical tables. Typical implementation places the A, B, and inhibit controls on digital I/O lines and routes sensor, measurement, or communication signals through the selected differential pair. If the source or destination is outside the mux's supported voltage range, protection and level shifting must be added. For battery-powered equipment, verify leakage and quiescent-current behavior, since those specifications are not present in the verified excerpt. A key design consideration is control-state timing during power-up. Select inputs should be held in a defined state before analog signals become active to prevent unintended channel connection. PCB routing should keep mux traces short, provide a solid ground reference, and place any external input and output protection close to the pins. This page combines the verified Texas Instruments product description, distributor specifications, package data, sourcing links, and engineering guidance. It also distinguishes documented values from parameters that require confirmation in the manufacturer datasheet, helping engineers evaluate CD4052BM procurement and design-fit requirements without inventing missing specifications.
CD4052BPWR - 4:1 Differential Analog Mux 240 Ohm | Texas Instruments
The Texas Instruments CD4052BPWR is a differential 4-channel analog multiplexer/demultiplexer from the CD405xB CMOS logic family, delivered in a 16-pin TSSOP (PW) package rated from -55C to +125C. It integrates two independent 4:1 switch circuits with binary control inputs A and B and an inhibit (INH) input, routing one of four differential channel pairs to a common connection over a wide 3V to 20V supply range. An analog multiplexer is a digitally controlled analog switch that connects one of several input signals to a single output. Within the signal-chain hierarchy, the CD4052B sits in the analog switches and multiplexers category of power and signal management ICs, serving as a fundamental building block between sensors or signal sources and ADCs, filters, or instrumentation amplifiers. Key features include a typical ON resistance of 240 ohms, very low OFF leakage current of approximately 100 uA class static consumption, and built-in logic-level conversion via the VEE pin, which allows CMOS or TTL-level logic inputs to control analog signals spanning the full supply range. Bidirectional signal flow supports both multiplexing and demultiplexing, and the INH input provides a high-impedance state across all channels. The device is fabricated in CMOS technology, delivering low static power consumption and high noise immunity. Analog signal swing extends to the full supply rails, making the part suitable for rail-to-rail signal routing. The TSSOP-16 body is 1.20 mm high with a 0.65 mm lead pitch for high-density surface-mount layouts. The part is RoHS compliant and lead-free. Typical applications include audio signal routing, data acquisition input selection, ADC front-end channel expansion, and test and measurement equipment; it is also used in automotive LIN circuits where its wide supply range is beneficial. Design tip: never exceed the 20V absolute maximum supply, place 100 nF decoupling capacitors close to VDD/VSS, and use the INH pin to implement channel isolation or power-down states.
CD4052QPWRQ1 - AEC-Q100 Dual 4:1 Analog Mux | TI
The Texas Instruments CD4052QPWRQ1 (CD4052BQPWRQ1 family) is an AEC-Q100 qualified CMOS differential 4-channel analog multiplexer/demultiplexer with logic-level conversion, supplied in a 16-pin TSSOP (PW) package. It functions as a digitally controlled analog switch that routes one of four differential signal pairs to a common output pair under control of a 2-bit address (A/B) and an active-low inhibit (INH) input. An analog multiplexer/demultiplexer is a bidirectional signal-routing device within the broader hierarchy of CMOS logic and analog switch ICs. Unlike digital-only multiplexers, the CD4052 family passes analog signals across the full supply range, with on-chip level shifting that allows logic inputs referenced to a low-voltage supply (VDD-VEE down to 3V) to control switches spanning up to 20V, making it usable in mixed-rail systems. Key features include a wide 3V to 20V supply range, logic-level conversion via VEE, break-before-make switching, low quiescent current typical of 4000B-series CMOS, and automotive qualification per AEC-Q100. Channel on-resistance is lowest at higher VDD; TI datasheet curves show typ values on the order of 100-300 ohm depending on supply and signal level [DATA_NEEDED: exact Ron typ]. The 4000B CMOS process provides high noise immunity, rail-to-rail analog signal handling, and very low static power consumption, which suits battery-powered and high-voltage industrial signal chains. Typical applications include automotive sensor signal routing, differential data acquisition front ends, audio signal selection, and industrial control multiplexing where a low-cost, high-voltage-tolerant switch is required. Design tip: keep the INH pin tied to a defined logic level (not floating) to avoid channel glitching, and observe the VDD-VEE total limit of 20V. Prices cited as of 2026-08-29.
CD4053BE - 20V Triple SPDT Analog Multiplexer | TI
The Texas Instruments CD4053BE is a 20 V, three-channel 2:1 SPDT analog multiplexer and demultiplexer with logic-level conversion, packaged in a 16-pin PDIP. Each channel can route one of two analog inputs to a common output, making the device useful for signal selection, instrumentation, test systems, and embedded control systems. The verified product description identifies a nominal 240 ohm switch resistance and a -55 °C to +125 °C operating-temperature range. An analog multiplexer is a switching IC that connects one of several physical signal paths to a shared resource. The CD4053BE belongs to the CD4000 CMOS logic family and combines three independent SPDT switch sections with address and enable control inputs. Its logic-level conversion feature helps bridge different voltage domains when the selected signals and control levels are compatible with the device’s published limits. Key verified features include a 20 V supply-related operating designation, three 2:1 switch circuits, 240 ohm on-resistance, 16-pin PDIP construction, and a temperature range from -55 °C to +125 °C. The 2:1 configuration is appropriate for selecting between two sources per channel rather than scanning a larger number of inputs. The DIP package favors breadboards, legacy industrial boards, prototype fixtures, and through-hole assemblies where a surface-mount package would be unsuitable. The CD4053B is specified as a CMOS analog multiplexer with logic-level conversion. Its control interface determines which analog terminal is connected to the common terminal of each section. Designers should account for signal amplitude, supply voltage, control logic levels, switch resistance, leakage, and the dynamic behavior of the connected source and destination circuits. The verified data does not provide complete timing, leakage, capacitance, or current-limit values, so those parameters should be taken from the manufacturer datasheet before final release. Typical applications include selecting between two sensors, routing one of two audio or communications sources, switching measurement channels in test equipment, and implementing sample-selection networks in industrial control systems. The device can reduce the number of external connections when several controlled signals share a downstream amplifier, converter, or controller input. A key design consideration is ensuring that the selected signal remains within the device’s published analog and control limits throughout operation. Avoid using the multiplexer as a power switch unless the relevant current, voltage, and transient requirements have been verified. Also account for off-channel injection and switch resistance when designing precision measurement paths. This page combines the verified Texas Instruments product data, distributor identification, practical application guidance, and a structured comparison framework. It also distinguishes confirmed CD4053BE attributes from parameters that require the complete manufacturer datasheet for engineering sign-off.
CD4053BM - 3-Channel 2:1 SPDT Analog Switch | TI
The Texas Instruments CD4053BM is a 20 V, 3-channel, 2:1 SPDT CMOS analog multiplexer and demultiplexer with logic-level conversion, housed in a 16-SOIC package. Each channel independently selects one of two analog terminals through controls A, B, and C, while a common inhibit input can disable the selected paths. Its 240 ohm on-resistance makes it suitable for routing moderate-frequency and low-voltage signals when a compact, low-cost multiplexer is required. What is a CMOS analog multiplexer? A CMOS analog multiplexer is a semiconductor switch that connects one common signal terminal to one of multiple channel terminals according to digital control logic. The CD4053BM is a triple SPDT device: each of its three switches has a common terminal and two selectable terminals, and the inhibit function provides shared control. In the signal-chain hierarchy, it is an analog switch, then a multiplexer or demultiplexer, and ultimately a logic IC with analog signal-routing capability. The verified manufacturer description identifies a 20 V supply, three independent 2:1 channels, and logic-level conversion. The CD4053BM can therefore support both analog multiplexing and demultiplexing functions, including source selection, signal routing, and shared test or measurement paths. The 240 ohm on-resistance listed by DigiKey is useful for impedance-sensitive designs because it can introduce signal attenuation and bandwidth limits when driving high-impedance or capacitive loads. In a typical circuit, the A, B, and C inputs determine which terminal of each SPDT switch connects to its common terminal. The inhibit input provides a common disable mechanism, allowing the circuit to isolate selected paths during test or control sequences. Logic-level conversion is useful when the control signals originate from a supply domain different from the analog signal supply. The device should be selected only when its voltage, current, temperature, and logic thresholds satisfy the actual signal path. Typical uses include sensor selection, instrumentation, analog signal routing, control systems, test equipment, and embedded measurement modules. Because the on-resistance is nonzero, avoid using the CD4053BM as a low-loss precision switch or for high-speed signals without checking bandwidth, charge injection, and capacitive-load behavior. The manufacturer product page is the authoritative source for ordering information, parameters, and support documents. A key design consideration is to account for the analog signal amplitude, supply voltage, control logic levels, and load impedance at the common terminals. Keep routing traces short, provide a stable supply reference, and ensure the control signals remain within the device's specified logic thresholds. The 16-SOIC footprint simplifies assembly in conventional through-hole-compatible surface-mount layouts, but the complete pinout and electrical limits must be checked against the official datasheet. This page combines the verified TI product description, distributor identification of the 16-SOIC package and 240 ohm on-resistance, and practical selection guidance. It does not invent unverified temperature, leakage, bandwidth, pricing, or absolute-maximum values; missing engineering parameters are marked for review in the specifications.
CD4054BF 4-Segment CMOS LCD Driver | Harris 16-CDIP
The Harris Corporation CD4054BF is a 4-segment CMOS liquid-crystal display driver packaged in a 16-CDIP ceramic DIP. The verified distributor data identifies it as a Liquid Crystal Driver, 4-Segment, CMOS, CDIP16 device. It belongs to the CD4000 CMOS logic family and decodes multiplexed or non-binary display data for four-segment LCD applications. A four-segment CMOS LCD driver is a specialized logic IC that accepts encoded display information and generates the segment-drive outputs required by multiplexed liquid-crystal displays. Within the display-driver hierarchy, it sits between general-purpose CMOS logic and application-specific LCD timing and segment-control circuitry. Its four-segment organization makes it useful for compact numeric, alphanumeric, or segmented indicators where a controller does not directly drive every display electrode. The verified product data specifically identifies the CD4054BF as a Harris Corporation part and describes a 4-segment LCD-driver configuration in a 16-CDIP package. The B suffix and ceramic package terminology indicate a packaged CD4000-series implementation, while the provided distributor listing classifies it under integrated circuits and display drivers. Detailed electrical timing, supply-voltage, output-drive, and temperature limits require the manufacturer datasheet before design release. CD4054BF applications include four-segment multiplexed LCD displays, compact numeric indicators, control-panel displays, embedded instrument panels, and low-power handheld equipment. The LCD-driver role is important because it reduces the amount of display-segment routing and control logic required around a system controller. Its CMOS implementation places it in the broader low-power semiconductor and integrated-circuit ecosystem. The principal design consideration is package and pinout validation. The CD4054BF uses a 16-CDIP package, so a replacement must use the same 16-pin footprint, confirm pin-to-pin signal compatibility, and verify the required supply voltage and display timing. Cross-reference search results identify CD4054BF variants and comparison pages, but they do not establish five verified drop-in replacements with complete package-level engineering data. This page consolidates verified distributor classification, source links, package information, and practical design guidance. Unavailable electrical values are explicitly marked for follow-up rather than inferred, allowing engineers to move from discovery to datasheet confirmation without treating guesses as specifications.
CD4056BF - CMOS BCD to 7-Segment LCD Decoder | Texas Instruments
The Texas Instruments CD4056BF is a CMOS BCD-to-7-segment LCD decoder/driver with a strobed latch, supplied in a 16-CDIP package according to the verified distributor listing. The available data identifies the device as an LCD display driver in the CD4056B family and associates it with the Harris Semiconductor datasheet SCHS048C, revised October 2003. The verified results do not provide the complete electrical limits, display drive voltage, output configuration, or timing values needed to reproduce a full datasheet specification table. A BCD-to-7-segment LCD decoder/driver converts a four-bit binary-coded decimal input into the seven segment drive lines required by a numeric display. The CD4056B family is associated with liquid-crystal display drivers, allowing a digital controller to present decimal digits without driving each display segment directly. The verified material specifically describes the CD4056B as a CMOS BCD to 7-segment LCD decoder/driver with strobed-latch functionality. The CD4056BF designation includes a CDIP package option, and the Rochester Electronics listing identifies a 16-CDIP package with a 0.300-inch, 7.62 mm lead pitch. The verified results also show distributor availability references, including an Octopart page for Texas Instruments and an FPGACenter listing for Rochester Electronics. Exact operating voltage, display output drive capability, propagation delay, quiescent current, and temperature ratings remain unavailable in the supplied excerpts and are intentionally not inferred here. Typical design use includes digital meters, counters, timers, calculators, and embedded instruments where a controller presents one decimal digit through an LCD. The strobed latch can support decoded display data being held while the system updates the input, although the exact latch and display timing should be confirmed from the manufacturer datasheet. Because the LCD bias, segment polarity, and output drive requirements depend on the display selected, the LCD specification must be reviewed before final PCB and component selection. Designers should confirm the package outline, pin numbering, supply voltage, input logic levels, segment outputs, common and backplane connections, and display bias arrangement against the original manufacturer documentation. The CD4056BF is a through-hole display-driver device in the listed CDIP option; it is not interchangeable with a surface-mount LCD driver without a footprint and pinout review. This page consolidates the verified CD4056BF datasheet links, distributor package information, procurement references, and design cautions. It deliberately distinguishes documented facts from unavailable parameters and does not substitute generic CD4000-series values for CD4056BF-specific ratings.
CD4060BK - 14-Stage CMOS Counter/Divider | Texas Instruments
The Texas Instruments CD4060BK is a CMOS 14-stage ripple-carry binary counter and divider with an integrated oscillator, operating from 3 V to 18 V and supporting operation up to 24 MHz in a 16-pin CFP surface-mount package. Its temperature rating extends from -55°C to +125°C. The device advances one count on each negative clock transition and provides 14 binary counter outputs, making it suitable for frequency division, timing, and clock-generation systems. A binary counter is a digital sequential circuit that stores and advances a count using binary-weighted stages. A divider extends this function by dividing an input frequency into a lower output frequency. The CD4000 CMOS logic family belongs to the broader logic IC and counter/divider hierarchy, combining low-power operation with wide supply-voltage flexibility. The oscillator and counter functions are commonly used together in timers, clock dividers, and programmable pulse-generation circuits. The verified CD4060B family data identifies 14 ripple-carry stages, operation from 3 V to 18 V, and a maximum clock frequency of 24 MHz. These ratings support both low-voltage logic systems and higher-voltage industrial or instrumentation environments. Its 16-CFP package offers a surface-mount option for compact assemblies, while the broad -55°C to +125°C temperature range supports demanding operating conditions. The ripple-carry architecture means each counting stage advances after the preceding stage, with the counter incrementing on the negative transition of the clock. Designers should account for accumulated propagation delay when dividing high frequencies or interpreting the relationship between clock edges and output transitions. The operating-frequency limit and external oscillator-component requirements must be checked against the manufacturer datasheet before establishing timing margins in a new circuit. Typical uses include divide-by-16 through divide-by-16384 clock generation, retriggerable pulse timing, periodic-event generation, and low-frequency clock derivation from a higher-frequency source. The oscillator pins can support an external resistor-capacitor network when stable autonomous operation is required, while an external clock can be applied when the system already provides a timing reference. PCB implementation should preserve short oscillator and clock paths, provide an unobstructed ground reference, and decouple the supply close to the device. Because the CFP-16 footprint is temperature- and package-sensitive, assembly should follow the manufacturer’s soldering and land-pattern recommendations. The verified source does not provide a complete pin-level table, so the final design should use the official CD4060B datasheet rather than an inferred pinout. This page consolidates verified manufacturer and distributor information, exact CD4060BK pricing evidence, package and environmental ratings, application guidance, and data-gap disclosures. It distinguishes documented facts from unavailable parameters and avoids presenting unverified substitute parts as drop-in replacements.
