ATF16V8C-7JI - 7.5ns 8-Macrocell EE PLD | Microchip
The Microchip ATF16V8C-7JI is a 5 V electrically erasable programmable logic device (EE PLD) with eight configurable macrocells, a 7.5 ns operating speed, and a 20-pin PLCC J-lead surface-mount package. It uses EECMOS architecture and electrically erasable flash memory to implement registered, complex, or combinational logic while retaining nonvolatile configuration memory. A programmable logic device is a semiconductor that stores user-defined Boolean logic in a nonvolatile configuration structure. The ATF16V8C belongs to the 16V8 SPLD family, combining a 20-pin PAL-compatible architecture with eight macrocells. Each output can allocate eight product terms, and software automatically configures the supported operating modes, allowing the device to implement more complex logic than basic combinational PAL devices. Key characteristics include an industry-standard 16V8 architecture, emulation of many 20-pin PAL devices, low-cost programming tools, CMOS and TTL-compatible interfaces, and a maximum pin-to-pin delay of 5 ns across the supported ATF16V8C speed options. The -7JI grade is identified in distributor data as an industrial-temperature 7.5 ns device. The family also includes a 100 µA pin-controlled power-down option, although the verified excerpt does not confirm that option for every suffix. Technically, the ATF16V8C combines EECMOS processing with nonvolatile flash-based configuration. This supports in-circuit reconfiguration without volatile configuration loss and allows the eight outputs to implement registered or combinational functions. Because the device targets 5 V systems, its input thresholds and output behavior should be checked against the connected CMOS or TTL logic rather than assumed from modern low-voltage devices. Typical applications include industrial control logic, interface decoding, state-machine implementation, glue logic, legacy control-panel logic, and compact combinational or sequential functions where a small PLD is more flexible than a fixed gate array. The 9 mm by 9 mm PLCC package also supports repair and upgrade programs that previously relied on 20-pin PAL devices. Designers should preserve the J-lead land pattern, validate the programmed fuse file against the selected architecture, and confirm input levels, timing, and unused-pin requirements in the manufacturer datasheet. This page combines verified manufacturer and distributor data, drop-in family options, and practical replacement guidance to support legacy PLD design maintenance.
ATF16V8C-7PI - 7ns 16V8 EECMOS PLD | Microchip
The Microchip Technology ATF16V8C-7PI is a 7 ns, 16V8-family EECMOS programmable logic device with eight macrocells, eight outputs, and a 20-pin PDIP package. It operates from a nominal 5 V supply, supports CMOS and TTL-compatible interfacing, and uses electrically erasable Flash memory for nonvolatile configuration. The industrial-temperature suffix identifies it for industrial applications, while the -7 speed designation corresponds to a 7 ns maximum pin-to-pin delay. An EECMOS PLD is a user-programmable digital logic device within the broader semiconductor and logic-IC hierarchy. Its Flash configuration memory allows a design to retain programmed Boolean equations after power removal, avoiding separate EPROM programming equipment. The ATF16V8C architecture implements a superset of generic 16R8 and many 20-pin combinatorial PAL architectures, providing eight product terms per output and flexible registered, combinatorial, and complex-mode configurations. Key features include a 7 ns maximum propagation delay for the -7 grade, eight macrocells, eight I/O outputs, a nominal 5 V operating supply, and low-power pin-controlled shutdown. The family supports operating speeds down to 5 ns, while the -7PI order code represents a 7 ns industrial-temperature option. Flash programmability simplifies in-circuit updates, and the device provides a practical migration path for compact glue-logic implementations formerly handled by multiple 20-pin PAL devices. The ATF16V8C uses EECMOS technology to combine nonvolatile configuration with CMOS-compatible logic. Product terms are automatically distributed among the eight macrocells according to the selected architecture and equations, allowing moderately complex control, decode, interface, and glue-logic functions in one package. CMOS and TTL compatibility simplifies connections to older host buses and peripheral logic, although designers should still verify voltage and timing requirements for every connected device. Typical applications include industrial interface decoding, legacy bus-control logic, address decoding, command multiplexing, alarm and sequencing logic, and compact peripheral adapters. The 20-pin PDIP format is especially useful for prototypes, legacy industrial equipment, and through-hole assemblies where a low-density programmable logic device is preferred over a larger FPGA or microcontroller. Design consideration: programmers should validate the JEDEC fuse state, operating-mode assignments, and AC timing against the actual board loads. Because the ATF16V8C is a fixed-architecture PLD rather than a general-purpose processor, it is most appropriate when the required Boolean equations fit within eight macrocells and eight product terms per output. This page consolidates verified manufacturer and distributor information, package-specific alternatives, pricing availability, pin assignments, and practical selection guidance. It also distinguishes true pin-compatible options from related speed grades that may alter timing margins even when they use the same PDIP footprint.
ATF16V8C-7SC - 7.5ns EECMOS PLD | Microchip | Logic Control
The Microchip Technology ATF16V8C-7SC is a high-performance EECMOS programmable logic device with a 7.5 ns pin-to-pin delay, eight macrocells, and a 20-SOIC package. It combines electrically erasable flash memory with CMOS and TTL-compatible inputs and outputs, making it suitable for implementing combinational and registered control logic in industrial electronic systems. A programmable logic device is a semiconductor whose internal digital functions are configured by stored programming data. In the product hierarchy, the ATF16V8C-7SC is a PLD, a specialized logic IC, and an integrated circuit. Its architecture can emulate many 20-pin PAL devices and most 20-pin combinatorial PLDs, providing a practical way to consolidate several fixed gate functions into one configurable device. Key features include eight macrocells, eight product terms allocated to each output, a 7.5 ns speed grade, and a pin-controlled power-down option that reduces supply current to 100 µA. Inputs and outputs support CMOS and TTL interfacing, while I/O pin-keeper circuitry helps retain input states. The device is specified for a commercial 5 V ±5% supply range, while faster and industrial-grade options are available elsewhere in the ATF16V8C family. The ATF16V8C incorporates a superset of the generic architectures used by the 16R8 family and many 20-pin combinatorial PLDs. Software automatically configures three operating modes, allowing the same physical device to support different registered, combinatorial, and mixed logic organizations. This flexibility makes it useful for legacy PAL replacement and compact control logic consolidation. Typical applications include industrial control interfaces, legacy 20-pin PAL replacement, address decoding, command and status logic, interface control, and fixed-function logic consolidation. The 20-SOIC package supports conventional surface-mount assembly, while electrically erasable flash technology allows a device to be reprogrammed without removing it from the circuit. Designers should verify the exact pinout, programming architecture, supply tolerance, and timing constraints against the manufacturer datasheet before substitution. A speed-grade change can affect system timing even when the package is unchanged, and an industrial-grade replacement may have different operating and qualification requirements. This page consolidates manufacturer specifications, sourcing information, package details, practical engineering guidance, and validated drop-in candidates. It also distinguishes genuine pin-compatible alternatives from slower family members that may require timing review.
ATF22V10C-10PU - 10-Macrocell 5V E2 PLD | Microchip
The Microchip Technology ATF22V10C-10PU is a 10-macrocell, electrically erasable programmable logic device operating from a nominal 5 V supply, with a 10 ns speed grade and a 24-pin through-hole PDIP package. It provides 500 programmable gates according to the Mouser product listing and combines CMOS logic with electrically erasable Flash-memory configuration technology. The device is intended for compact control, decoding, address mapping, glue logic, and legacy GAL22V10-compatible designs. A simple programmable logic device is a semiconductor that stores a Boolean function as a configuration rather than implementing that function through fixed gates. The ATF22V10C belongs to the SPLD and PLD hierarchy, where product terms fuse map, macrocell, and erasable Flash configuration describe how each of its 10 logic macrocells implements registered or combinational logic. This makes the device useful as bridge logic between larger processors, FPGAs, memory devices, and industrial or communications systems. Verified product information identifies 10 macrocells, 500 gates, a 5 V supply, a 10 ns speed designation, and a 24-pin PDIP package. The manufacturer datasheet states that the ATF22V10C family reaches speeds down to 5 ns and low typical power dissipation, while the exact ATF22V10C-10PU operating-temperature limits, current consumption, I/O counts, and AC timing values are not supplied in the verified excerpts. Those values must therefore be confirmed in the manufacturer datasheet before a new design is released. The device architecture is appropriate for deterministic control paths, fuse-map decoding, bus-interface qualification, and small state machines. Microchip support identifies the ATF22V10C family as pin-to-pin and JEDEC-fusemap-compatible replacements for GAL22V10 devices when AC and DC behavior is compatible. Because this -10PU variant is a 10 ns speed grade, systems must preserve setup and timing margins rather than treating the number as a universal operating frequency. Typical uses include industrial control, legacy peripheral emulation, address decoding, signal conditioning, test adapters, and compact control logic where 500 gates of programmable integration are sufficient. Mechanically, the PDIP format supports conventional through-hole assembly, prototyping, repair, and legacy boards. Surface-mounted systems should not assume that another ATF22V10C package is interchangeable because package drawings, pin availability, and assembly requirements differ. The main design consideration is configuration compatibility. Confirm the JEDEC fuse map, pin assignments, supply voltage, timing grade, output-drive assumptions, and unused-pin treatment against the exact manufacturer datasheet. A nominal 5 V part should not be assumed suitable for 3.3 V systems without an explicit rail-level specification. For production, validate programming algorithms, erase-and-program behavior, and system timing under worst-case supply and temperature conditions. This page combines verified manufacturer and distributor facts with explicit data gaps, package-aware replacement guidance, comparison parameters, and practical legacy-logic design notes. It is intended to accelerate component identification while preventing unverified electrical or lifecycle assumptions from entering a production BOM.
ATF22V10C-5JC - 500-Gate EE PLD, 10 Macrocells, 5ns | Microchip
The Microchip ATF22V10C-5JC is a high-performance CMOS electrically erasable programmable logic device (EE PLD) providing 500 logic gates in 10 macrocells, with 5 ns propagation delay, packaged in a 28-pin J-lead PLCC (QCCJ, 11.51 mm x 11.51 mm) surface-mount package. It operates from a single 5 V supply with commercial-grade 5 V +/- 5% tolerance and consumes as little as 10 uA in power-down state. The device replaces the legacy fuse-programmed GAL22V10 architecture with in-circuit electrically erasable flash memory, so a design can be re-programmed without a programmer socketed into a dedicated fixture. An EE PLD is a programmable logic device whose configuration memory is non-volatile and re-writable. Within the wider semiconductor hierarchy, ATF22V10C sits in the programmable logic family, which sits inside the broader logic IC and programmable logic device categories. A GAL22V10-style device maps a fixed sum-of-products architecture onto 10 macrocells, each with 8 product terms feeding an OR plane plus a configurable flip-flop. That structure makes the ATF22V10C a natural fit for glue logic, control decoding, address decoding and bus arbitration logic that must be re-worked late in a design cycle. Key electrical features include a 5 ns minimum tPD, 10 macrocells of 500 total gates, a 28-pin PLCC footprint, an input latch feature that holds inputs at their previous logic states, and flash-based in-circuit re-programming. Unlike mask-programmed or OTP alternatives, the ATF22V10C can be updated on the assembly line, which shortens NPI schedules and eliminates disposal of obsolete programmed parts. Technically, the ATF22V10C is architecturally compatible with the classic GAL22V10 JEDEC fuse map, so existing GAL22V10 pinouts, fusing tables and JEDEC third-party programmer support carry over directly. Microchip publishes the ATF22V10C as the recommended replacement for the GAL22V10, noting that AC and DC characteristics are very similar with only minor differences. Typical applications include address decoding for memory and peripheral buses, control-plane state machines for industrial and instrumentation equipment, retrofit glue logic around legacy microcontrollers, ASIC prototyping, and interface logic in test and measurement equipment. The 28-pin PLCC package gives short, low-inductance leads that support both hand soldering and reflow at 5 V clock speeds. When designing around the ATF22V10C, remember that its 10-macrocell architecture maps to classic GAL22V10 JEDEC equations; use a JEDEC-compatible programmer and verify the fuse map against the vendor library before taping out. Place a 0.1 uF decoupling capacitor at each supply pin and keep PLCC leads short to limit ground bounce on fast output transitions. This page consolidates verified distributor specifications for the ATF22V10C-5JC, pin-compatible drop-in alternatives, JEDEC fusemap compatibility notes, and practical design guidance that is not consolidated in a single manufacturer document.
ATF22V10C-5JX - 5ns 500-Gate EE PLD | Microchip Technology
The Microchip Technology ATF22V10C-5JX is a 5 ns, 500-gate electrically erasable programmable logic device with 10 macrocells, supplied in a 28-pin PLCC package measuring 11.51 mm by 11.51 mm. It operates from a 5 V supply and combines a 166 MHz maximum device frequency with electrically erasable Flash-memory configuration. The ATF22V10C series provides a practical way to implement compact glue logic, address decoding, control sequencing, and interface adaptation where a small microcontroller or FPGA would be unnecessary. A programmable logic device, or PLD, is a semiconductor whose digital function is defined by stored programming data rather than fixed logic. The ATF22V10C belongs to the simple PLD hierarchy: PLD > simple PLD > SPLD > electrically erasable PLD. Compared with a mask-programmed PAL device, its Flash-memory configuration can be changed during development, simplifying logic revisions, prototype corrections, and production programming workflows. Key features include 10 macrocells, approximately 500 gates, a 5 ns speed grade, a 166 MHz stated maximum frequency, and 5 V operation. The electrically erasable Flash architecture retains the programmed function without continuous electrical rewriting. According to the manufacturer datasheet, power dissipation can be as low as 10 uA typical, making the device useful where low standby consumption is valuable. A pin-controlled power-down feature is also available, with the PD function located on pin 5 for PLCC packages. The ATF22V10C-5JX is an older, compact CMOS PLD rather than a field-programmable gate array. Its 10 macrocells provide substantially less logic capacity than modern CPLDs and FPGAs, but the 5 ns speed class supports faster decision and decoding paths than slower SPLD grades. The main design trade-off is fixed logic capacity: complex state machines, wide arithmetic functions, and large parallel interfaces may exceed the available macrocells even when the propagation delay is suitable. Typical applications include industrial control address decoding, peripheral-chip-select generation, asynchronous interface adaptation, embedded reset and power sequencing, test-fixture control, and compact legacy-controller support. Because the device is electrically erasable, it is especially useful for bridge or glue logic that must evolve independently of a larger system-on-chip. Its J-lead PLCC package also provides a practical surface-mount option for boards that cannot accommodate a through-hole DIP package. Designers should confirm that the required Boolean equation set fits the 10 macrocells and should verify the JEDEC-compatible fuse map before replacing a GAL22V10 or designing a new board. Programming tooling and the correct ATF22V10C device family must be selected. The 5 V supply, 5 ns timing grade, and PLCC footprint should all be checked against the existing schematic and PCB library before procurement. This product page consolidates manufacturer specifications, distributor pricing, package information, and verified replacement information. It also provides practical selection guidance for ATF22V10C speed grades and clearly distinguishes verified drop-in candidates from options that change speed grade, temperature grade, package, or device architecture.
ATF22V10C-7JC - 500-Gate 7 ns EE PLD | Microchip Technology
The Microchip Technology ATF22V10C-7JC is a 500-gate electrically erasable programmable logic device with 10 macrocells, a 5 V supply, and a 7 ns speed grade, housed in a 28-pin PLCC package. It belongs to the ATF22V10C family of CMOS PLDs and provides a practical combination of combinational logic capacity, flash-based reprogrammability, and surface-mount integration for established control and interface designs. An electrically erasable PLD is a user-programmable logic device whose configuration is stored in nonvolatile memory. In the broader semiconductor hierarchy, the ATF22V10C-7JC is a PLD, then a programmable logic device, then an integrated circuit, and finally a semiconductor. Its ten macrocells make it suitable for compact glue-logic implementations, pin mapping, control decoding, and other functions that can be consolidated into one device rather than implemented with multiple conventional logic ICs. The verified product information identifies the device as a 22V10-series EE PLD with 500 gates, 10 macrocells, a 5 V operating supply, and a 7 ns speed designation. A separate distributor listing describes the propagation delay as 7.5 ns, so the two published figures should be checked against the applicable datasheet revision and test conditions before using the timing figure for a safety-critical design. The family documentation also describes electrically erasable flash memory, low-power operation, and speeds down to 5 ns across the broader ATF22V10C range. The ATF22V10C architecture provides multiple product-term configurations for the ten output macrocells. Microchip documentation states that the family supports programmed operating modes and that related ATF22V10CZ and ATF22V10CQZ devices form a superset of generic 22V10 architectures. The ATF22V10C series also offers an optional pin-controlled power-down function; in the PLCC package, the power-down signal is identified at pin 5 in the manufacturer documentation. Typical uses include industrial control logic, interface decoding, legacy peripheral emulation, counter or state-machine implementation, and compact control logic in otherwise discrete-logic systems. The 28-pin PLCC footprint is especially relevant to maintenance and redesign work involving boards designed around the classic 22V10 architecture. Its nonvolatile, electrically erasable configuration also supports repeatable engineering changes without a dedicated ultraviolet-erase step. When designing around the ATF22V10C-7JC, preserve the manufacturer's pin assignment and programming-device requirements, and do not substitute a PLD solely because its gate count is similar. Verify the JEDEC fuse-map compatibility, supply voltage, macrocell product-term allocation, active levels, timing grade, and temperature designation against both the target and proposed replacement datasheets. The verified data does not supply exact package dimensions beyond the 28-pin PLCC identification, so mechanical drawings should be taken from the official package documentation. This page combines the verified manufacturer and distributor information, genuine cross-reference candidates, application guidance, and pin-compatibility cautions rather than repeating raw catalog data alone. It also separates confirmed device facts from fields that remain unavailable, helping engineers evaluate this legacy PLD and any replacement before committing a board layout or production order.
ATF22V10C-7JI - 10-Macocell 5V EE PLD | Microchip
The Microchip Technology ATF22V10C-7JI is a 10-macocell electrically erasable programmable logic device (EE PLD) with a 7.5 ns propagation delay, 5 V input voltage, and a 28-pin PLCC J-lead package. It belongs to the ATF22V10C family and uses electrically erasable Flash memory, allowing the implemented logic design to be reprogrammed during development or field updates. An EE PLD is a semiconductor whose digital logic function is user-programmed through a configurable internal array. The ATF22V10C-7JI provides 10 macrocells, equivalent to approximately 500 gates according to distributor data. This makes it useful for implementing fixed combinational and registered logic, interfacing legacy systems, consolidating small amounts of glue logic, and providing compact control functions in industrial automation, consumer electronics, and telecommunications equipment. Key characteristics include a 7.5 ns speed grade, operation from a 5 V input supply, surface-mount construction, and an industrial temperature grade. The family also provides an optional pin-controlled power-down function in which the PD control appears on pin 5 of the PLCC package. Electrically erasable Flash technology gives the device a different programming and update model from one-time-programmable fuse-based PAL and GAL devices. The ATF22V10C architecture combines programmable input and output structures with dedicated clock and output-enable functions. The device can implement registered logic through its macrocell flip-flops while retaining the familiar JEDEC-compatible 22V10 logic arrangement. This architecture is intended for designs requiring more flexibility than a fixed gate array but less complexity than a modern FPGA. Typical uses include industrial control logic, communication-interface decoding, address and command multiplexing, legacy peripheral adaptation, and compact system-control functions. Because the device is packaged in a 28-pin PLCC, it is particularly relevant to equipment upgrades that already use that footprint and JEDEC-compatible logic mapping. When replacing an older GAL22V10 implementation, verify the programmed fuse map, pin-controlled power-down behavior, timing grade, temperature range, and supply requirements against the manufacturer datasheet. The PLCC footprint is suitable for surface-mount assembly, but exposed-pad thermal analysis is not applicable because this package does not contain an exposed thermal pad. This product page consolidates verified source data, sourcing information, specification comparisons, and application-oriented design guidance. It also distinguishes documented drop-in alternatives from broader functional replacements and identifies the specific details that must be checked before substituting a legacy programmable-logic device.
ATF22V10C-7PC - 7ns 500-Gate Flash PLD | Microchip Technology
Microchip Technology ATF22V10C-7PC is a 7 ns, 500-gate electrically erasable CMOS programmable logic device with 10 macrocells, supplied in a 24-pin PDIP package. It uses electrically erasable Flash memory and operates from a 5 V supply, combining reconfigurable digital logic with a through-hole package suited to legacy control, interface, and industrial automation systems. An EEPLD is a programmable logic device that stores a logic configuration in nonvolatile memory. The device sits within the hierarchy of programmable logic devices, including simple PLDs, complex PLDs, FPGAs, and CPLDs. Unlike a mask-programmed logic array, the ATF22V10C-7PC can be erased and reprogrammed, allowing the same board design to support multiple logic configurations, design revisions, or field updates. The principal performance characteristics are a 7 ns device speed, 500 equivalent gates, 10 macrocells, 5 V operation, and nonvolatile Flash-backed configuration storage. The ATF22V10C family also includes speed options down to 5 ns, and Microchip documents power dissipation as low as 10 μA typical for the family. The commercially graded -7PC ordering code identifies the 7 ns variant in the 24-pin PDIP package. Architecturally, the device implements sum-of-products logic through a fuse-map-compatible PLD arrangement. Microchip identifies the ATF22V10C, ATF22V10CQ, and ATF22V10CQZ as suitable replacements for the GAL22V10 because they are pin-to-pin and JEDEC fuse-map compatible. Electrical and timing characteristics should still be compared against the original GAL22V10 datasheet before substituting them into an existing design. Typical uses include industrial control signal decoding, legacy peripheral interfacing, custom logic functions, product routing, test-fixture control, and small control systems where a compact 10-macrocell PLD is more practical than a larger FPGA. Its nonvolatile Flash configuration also avoids loading the programming pattern into volatile memory after each power-up. Designers should preserve the published 24-pin footprint, supply requirements, timing limits, and output-drive constraints when replacing a GAL22V10 or another compatible PLD. Because the verified source set does not provide a complete pin list, electrical limits, or detailed AC timing tables, those values must be confirmed in the manufacturer datasheet before layout release or production use. This page consolidates verified Microchip and distributor information, identifies same-package replacement candidates, and separates confirmed parameters from data that still requires datasheet review. This added context helps engineers compare ATF22V10C-7PC with legacy PAL/GAL logic without mistaking package similarity for guaranteed system compatibility.
ATMXT224S-CCUR - 224-Node Touchscreen Controller | Microchip
The Microchip Technology ATMXT224S-CCUR is a capacitive touch screen controller IC from the maXTouch S-series family, featuring 224 mutual-capacitance sensing nodes and support for 1.5 mm passive stylus operation. It is supplied in a surface-mount package (per manufacturer product page; package variant code CCUR) and is designed for high-performance smartphone and tablet touchscreen applications. A capacitive touch screen controller is an integrated circuit that scans a grid of electrodes embedded in a touch panel, measures mutual capacitance changes caused by finger or stylus contact, and applies proprietary algorithms to convert raw signals into accurate touch coordinates. Within the signal-chain hierarchy, the touch controller sits between the touch sensor (passive ITO electrode matrix) and the host application processor, communicating touch data over an I2C or SPI interface. Key features of the ATMXT224S include 224 sensing nodes supporting touch panels up to roughly 8-9 inches, Microchip's patented capacitive touch technology, and passive stylus support at 1.5 mm tip width. These capabilities enable slim bezels, accurate handwriting input, and multi-touch performance required by premium mobile devices. Technically, the maXTouch S-series integrates a dedicated touch-processing engine with Microchip's noise-suppression algorithms, providing immunity against charger and display noise - a critical requirement as displays and charging circuits inject common-mode interference into touch panels. Typical applications include smartphones, tablet touch panels, portable media players, and industrial human-machine interfaces (HMI) that require multi-touch and stylus input. Important design consideration: Microchip's official product page for ATmXT224S states that the recommended alternative touch controller is the ATMXT336U, and the mXT224S is being superseded; new designs should evaluate the successor family. Firmware/configuration data is programmed into the maXTouch controller at production, so design-in requires Microchip's maXTouch development tools. This page synthesizes verified distributor pricing, lifecycle status, and alternative controller guidance not consolidated in the manufacturer datasheet.
ATMXT336S-MAUR - 336-Node Touchscreen Controller IC | Microchip
The Microchip Technology ATMXT336S-MAUR is a maXTouch 336-node mutual-capacitance touchscreen controller IC designed for high-performance smartphones and mobile devices, delivered in a reel-packaged surface-mount package (MAU suffix). A capacitive touchscreen controller is a mixed-signal IC that drives and senses a grid of mutual-capacitance nodes on a touch panel, converts raw capacitance changes into digitized touch coordinates, and reports gesture data to a host processor. Within the power management and human-interface hierarchy, it sits between the passive touch panel and the application processor, forming part of the sensor and interface IC layer of a mobile system. Key features include 336 mutual-capacitance sensing nodes, support for 2.0 mm passive stylus input, moisture robustness for wet-finger tracking, and superior electrical noise immunity for operation in hostile AC-charger and display-noise environments, according to the Microchip product page. The maXTouch architecture uses patented capacitive touch acquisition technology with on-chip signal processing, enabling high signal-to-noise ratio touch reporting at high report rates. This makes the mXT336S well suited to dense sensor patterns on thin phone form factors where water rejection and stylus resolution are critical differentiators. Typical applications include premium smartphone touchscreens, small-to-medium tablet and phablet panels, and portable consumer devices requiring passive stylus support and wet-hand operation. When designing with the mXT336S, confirm panel node count and pin mapping against the maXTouch family configuration, and note that Microchip officially recommends the ATMXT336U as the alternative touch controller for this part. This page synthesizes verified distributor pricing, the Microchip-recommended alternative, drop-in family options, and practical sourcing guidance not consolidated in the manufacturer datasheet alone.
BCM47083SJ03 - 2+3GE WLAN 11N/11AC SoC | Broadcom
The Broadcom BCM47083SJ03 is a 2+3 Gigabit Ethernet WLAN chipset system on chip supporting 802.11n and 802.11ac in a tray package. The verified product description identifies a two-plus-three Gigabit Ethernet configuration, meaning two integrated Gigabit Ethernet MAC/PHY positions and three additional Gigabit Ethernet interfaces supported by the chipset family. The device is positioned for embedded networking equipment that combines wired Ethernet connectivity with dual-band wireless LAN capability. An embedded wireless system on chip is an integrated semiconductor platform that combines a network processor, Ethernet controllers, wireless radio functions, memory interfaces, and associated control logic. In the product hierarchy, BCM47083SJ03 is a WLAN chipset, an RF system-on-chip, an embedded networking processor, and ultimately a semiconductor designed to reduce the component count required in a router, access point, or connected home gateway. This integration simplifies PCB layout while requiring careful power, thermal, antenna, and Ethernet signal-integrity design. The principal documented feature is support for 802.11n and 802.11ac WLAN operation together with a 2+3 Gigabit Ethernet arrangement. The verified listings classify the part as a “2+3 GE WLAN chipset (11N+11AC).” This combination is relevant to multi-port routers, cable gateways, enterprise wireless access points, and consumer gateways that need several Ethernet connections while retaining Wi-Fi capability. The exact processor clock, memory interface, radio band coverage, and port-level electrical ratings are not stated in the supplied source data and must be confirmed from the manufacturer documentation before design release. Broadcom markets the BCM47083 family as an RF system-on-chip for embedded networking applications. Integrating the WLAN and Ethernet functions into one device can reduce external component count and simplify software bring-up compared with a processor-based design using discrete Ethernet PHYs. However, integrated functionality does not remove the need for careful board partitioning: high-speed digital interfaces require controlled return paths, while radio, Ethernet magnetics, clocks, and power conversion must be isolated to prevent interference. Typical uses include gigabit routers, dual-band wireless access points, home gateways, set-top gateways, and embedded network appliances. In a router application, the BCM47083SJ03 can provide the central combination of multi-gigabit wired connectivity and 802.11n/802.11ac wireless networking. The same general architecture can support access-point designs where Ethernet ports backhaul wireless clients, although radio calibration, antenna matching, regulatory configuration, and country-specific channel requirements remain system-level tasks. Designers should not release a PCB based only on distributor summaries. The official package drawing, exposed-pad or ground-ball details, pin assignments, recommended power rails, decoupling network, crystal or oscillator requirements, Ethernet magnetics interface, and reference schematic must be obtained before layout begins. The supplied data identifies tray packaging but does not provide the exact package dimensions, ball count, pin map, or exposed thermal construction. These omissions are recorded in the specification fields rather than inferred from similar Broadcom devices. This product record consolidates verified distributor descriptions, stock references, package-format information, application context, and qualified replacement guidance that are not presented together on a manufacturer product page. It also separates confirmed BCM47083SJ03 attributes from specifications that require the official datasheet, preventing assumptions about unverified processor, RF, memory, thermal, and compliance details.
BCM5396IFB - 16-Port Gigabit Switch | Broadcom
Broadcom BCM5396IFB is a 16-port Gigabit Ethernet switch with integrated SerDes, delivering a 17-Gigabit non-blocking switching fabric in a BGA package. It includes seventeen IEEE 802.3-compliant MACs, sixteen SGMII/SerDes interfaces, a 256-KB packet buffer, and one GMII/RGMII/RvMII uplink. An Ethernet switch is a semiconductor that receives Ethernet frames on multiple ports, stores them briefly, examines addressing information, and forwards each frame only toward its destination port. The BCM5396 combines physical-layer SerDes interfaces, Media Access Controllers, address management, packet buffering, and switching control within one monolithic 0.13 µm CMOS device. This integration reduces the component count required for multiport Gigabit networking equipment. The verified BCM5396 data identifies sixteen SGMII/SerDes ports, seventeen compliant MACs, one GMII/RGMII/RvMII interface, and a non-blocking 17-Gigabit Ethernet switch fabric. It supports jumbo frames up to 9 KB and includes a 256-KB packet buffer. The Broadcom datasheet also states compliance with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x, including MAC-control PAUSE handling. Technical implementation centers on the integrated SerDes interfaces and the internal switching architecture. Sixteen Gigabit Ethernet links terminate through SGMII/SerDes, while a separate parallel interface supports an uplink or management-facing port. The switch fabric is designed to forward traffic without a blocking bottleneck across the aggregate 17-Gigabit capacity, and packet buffering absorbs short traffic bursts before forwarding decisions are completed. Typical applications include 16-port Gigabit Ethernet switches, industrial network equipment, network-interface appliances, aggregation equipment, and embedded systems requiring multiple copper or fiber-linked Ethernet ports. The parallel uplink can connect the switched ports to a host processor, another switch, or a router, depending on the surrounding system architecture. PCB design must follow the manufacturer’s BGA land pattern, ball assignment, power, clock, SerDes, and decoupling requirements. Differential high-speed pairs need controlled impedance, uninterrupted reference planes, minimized stubs, and manufacturer-recommended spacing. Because the supplied excerpts do not include operating voltage, temperature range, pin list, or exact package dimensions, those values should be confirmed from the full manufacturer datasheet before release. This product record combines verified source links, procurement fields, interface facts, and design-focused context. The alternatives list remains intentionally limited because the supplied cross-reference search did not identify any verified pin-compatible replacement MPNs.
BCM5396KFB - 16-Port Gigabit Switch IC | Broadcom
The Broadcom BCM5396KFB is a 16-port Gigabit Ethernet switch integrated circuit with integrated SerDes, specified in a 256-pin FBGA package and a 16,000 Mbps switching capacity. It combines the packet buffer, Media Access Controllers, address management, and a non-blocking switch controller in one monolithic 0.13 µm CMOS device, providing a compact foundation for multiport Ethernet systems. A Gigabit Ethernet switch is a network-semiconductor device that receives Ethernet frames through multiple ports, maintains the required MAC and address information, and forwards traffic through an internal switching fabric. Ethernet switching belongs to networking and communications electronics, where throughput, port density, media interfaces, buffering, and frame handling determine whether a system can support simultaneous data flows without unnecessary contention. The BCM5396KFB's principal verified features include 16 Gigabit Ethernet ports, integrated SerDes, and a non-blocking switch controller. Its listed aggregate throughput is 16,000 Mbps. The Broadcom datasheet also states compliance with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3x, including MAC-control PAUSE-frame support. These functions place the device in the family of Ethernet interface and switching semiconductors rather than a general-purpose microcontroller or standalone physical-layer transceiver. The monolithic 0.13 µm CMOS implementation consolidates packet buffering, MACs, address management, and switching control. That integration can reduce the number of external network components in a designed platform, although board-level operation still depends on power delivery, clocking, SerDes implementation, thermal conditions, magnetics or PHY integration, and validated firmware or driver support. The supplied distributor references classify the part as a 16-port layer-2 Gigabit switch with integrated SerDes. Typical equipment uses include 16-port managed Gigabit Ethernet switches, industrial Ethernet aggregation, network-interface appliances, telecom access equipment, and embedded systems that need multiple copper or fiber-facing ports. These uses are consistent with the verified 16-port architecture; exact supported media type, connector arrangement, electrical limits, and board implementation must be confirmed from the complete manufacturer datasheet before release. Engineers should preserve the manufacturer's ball map, power and decoupling layout, thermal design, and high-speed routing constraints. A 256-pin FBGA is demanding to route and inspect, so assembly yield, via-in-pad policy, solder-mask definition, and X-ray or AOI coverage should be reviewed early. This page separates verified facts from unavailable electrical details and avoids treating distributor classifications as substitutes for a complete pinout. This page consolidates distributor sourcing, datasheet references, design cautions, and strict drop-in-compatibility checks that are not available from a bare distributor listing. Because no verified substitute shares the exact BCM5396 footprint and electrical configuration, engineering review is required before any proposed replacement is approved.
BCM5665KPB - 48FE+4FE HiGig Switch | Broadcom
The Broadcom BCM5665KPB is a StrataXGS BCM5665 integrated multilayer switch with 48 Fast Ethernet ports plus 4 additional Fast Ethernet interfaces, supplied in a [DATA_NEEDED: package]. It is designed for telecom-oriented Ethernet switching systems in the Interface ICs category, where integrated Layer 2 and Layer 3 switching functions consolidate multiple physical ports into a dedicated switching device. The verified distributor results identify the BCM5665 family and describe the KPB part as a 48FE+4FE HiGig switch, but they do not provide the complete electrical, timing, thermal, package, or pinout data needed for a definitive hardware design. A switch ASIC is an integrated circuit that moves Ethernet frames between ports using dedicated switching resources and integrated packet-processing functions. In the semiconductor hierarchy, this device is a network switch, interface IC, Ethernet switching ASIC, and specialized semiconductor. Unlike a general-purpose processor, its primary role is high-throughput frame transfer and network-traffic handling rather than software execution. The BCM5665 series is relevant to telecom access, aggregation, and carrier Ethernet equipment, subject to the exact Broadcom product documentation. The verified listing provides one concrete functional description: 48FE+4FE HiGig switching. This notation indicates 48 Fast Ethernet ports and four additional Fast Ethernet ports. However, the source does not define whether those four ports are copper, fiber, integrated PHY, or otherwise exposed through a specific interface. No supported switching fabric rate, packet rate, MAC address size, memory interface, process voltage, operating temperature, or power consumption is present in the supplied material. A typical telecom implementation would place this switch ASIC on a line card or aggregation platform, connect front-panel Fast Ethernet interfaces to access traffic, and route frames internally between line cards or uplink ports. Such a design requires the manufacturer pinout, recommended reference design, power rails, clocking, reset requirements, SerDes or PHY documentation, thermal data, and PCB constraints. Those details must be obtained before schematic capture or layout begins. The principal design consideration is procurement risk. This appears to be a legacy Broadcom networking device introduced around 2001 according to the supplied GlobalSpec result, and search results describe supply as limited. Buyers should authenticate source, inspect date codes, request traceability, and obtain manufacturer lifecycle notices rather than assuming new-production availability. Counterfeit screening is especially important for obsolete or legacy telecom semiconductors. This page consolidates verified distributor identity, port-family information, sourcing links, and explicit engineering-data gaps. It intentionally avoids inventing clock rates, package dimensions, electrical limits, pin names, or replacement parts because the supplied evidence does not establish those values. Before purchase or design-in, request the exact Broadcom datasheet, package drawing, revision history, and written lifecycle status directly from Broadcom or an authorized source.
CD4010BE - CMOS Hex Buffer/Converter | Texas Instruments
The Texas Instruments CD4010BE is a CMOS hex non-inverting buffer/ converter with six one-bit elements, push-pull outputs, and a 16-pin PDIP package. It is designed for CMOS-to-TTL or DTL logic-level conversion and can also serve as a CMOS high-sink-current driver. The verified manufacturer product information identifies the device as a 16-pin non-inverting hex buffer/converter operating across a temperature range of -55 °C to 125 °C. A logic buffer is a digital IC that reproduces a binary input at its output while providing buffering, isolation, or voltage-level translation. A level converter sits within the broader hierarchy of logic ICs and interface ICs, connecting circuits that use different voltage domains. The CD4010BE belongs to the CMOS 4000-series logic family and combines six non-inverting conversion channels in one through-hole package. The six-element architecture allows multiple logic signals to be buffered within a single integrated circuit. Each channel operates as a one-bit, non-inverting element, while the push-pull output configuration provides a defined output arrangement. This makes the part relevant to legacy digital systems that need a compact solution for translating logic levels or driving multiple CMOS loads without changing an existing DIP-based board. The CD4010BE can be used as a CMOS-to-TTL or DTL interface element because the manufacturer documentation specifically identifies those conversion roles. It can also operate as a CMOS high-sink-current driver, providing a useful distinction from a plain passive buffer. The 16-lead PDIP format supports conventional through-hole PCB assembly and is compatible with standard 7.62 mm pitch layouts. Typical uses include legacy processor and peripheral interface circuits, control-logic boards, instrumentation, industrial control systems, and repair or modernization of equipment built around TTL and CMOS logic. In a level-shifting circuit, one CD4010BE can handle six related signals, reducing component count compared with discrete converters. Its non-inverting behavior preserves the logical relationship between each input and corresponding output. The primary design consideration is that this is a DIP-16 through-hole device rather than a surface-mount part. Board layout, connector spacing, assembly method, and mechanical clearance must therefore account for the package dimensions and 7.62 mm lead pitch. Engineers should also verify operating voltage, input levels, output drive, and timing against the complete manufacturer datasheet before using the converter in a new voltage domain. This product page consolidates verified manufacturer and distributor information, sourcing details, technical comparisons, and practical replacement guidance. It is designed to help engineers evaluate the CD4010BE, locate its documentation, understand its intended logic-converter role, and determine whether a verified drop-in substitute is available for an existing 16-pin design.
CD4010BM - Hex Non-Inverting Buffer | Texas Instruments
The Texas Instruments CD4010BM is a CMOS hex non-inverting buffer and converter containing six independent 1-bit buffer elements with push-pull outputs, supplied in a 16-pin SOIC package. Its rated operating temperature range is -55°C to 125°C, and the device is qualified at 5 V, 10 V, and 15 V parametric supply levels. Maximum input current is specified as 1 µA at 18 V across the full package-temperature range, with a typical value of 100 nA at 18 V and 25°C. The manufacturer also specifies 100% testing for quiescent current at 20 V. A CMOS logic buffer is an interface device that reproduces a binary input signal at its output without changing its logic polarity. In the signal-processing hierarchy, this six-channel device belongs to the CMOS logic family and the broader category of buffers and logic-level converters. The non-inverting configuration preserves high and low logic states, making the CD4010BM useful for signal buffering, distribution, and CMOS-to-TTL or DTL interface applications. The six independent channels provide flexible implementation of parallel data paths, control-signal isolation, fanout distribution, and logic conversion. Push-pull outputs are suitable for driving CMOS loads and support reliable operation at both logic levels. Operation is supported at 5 V, 10 V, and 15 V parametric ratings, while the verified 18 V input-current data indicates a maximum supply operating point of 18 V. The specified low input current helps minimize loading on the driving circuit. The CD4010B family was designed around CMOS operating principles and provides independent non-inverting channels rather than a shared multiplexed data bus. This architecture avoids the bus-sharing restrictions of multiplexers and allows every input and output to be used simultaneously. The manufacturer documentation specifically identifies the CD4010B family for use as CMOS-to-TTL or DTL logic-level converters and as CMOS high-sink-current drivers. Typical applications include buffering multiple digital control lines, translating slow or lightly loaded CMOS signals into more capable logic-driver outputs, distributing clock or gate signals, and supporting industrial or embedded systems that mix CMOS and legacy TTL or DTL interfaces. Six channels in one 16-pin package also reduce board area compared with six discrete single-channel buffers. Because the outputs are non-inverting, the part is preferable where polarity must remain unchanged. Designers should verify input and output voltage levels against the load technology rather than assuming every TTL interface is guaranteed at every supply condition. Unused input pins must not float, and unused outputs should be left unconnected unless required by a specific test configuration. The 16-pin SOIC package also requires adequate lead spacing and soldering time appropriate for a 1.27 mm-pitch surface-mount footprint. This page consolidates the verified manufacturer and distributor information, identifies the supported voltage and temperature qualifications, clarifies the limitations of drop-in replacement data, and provides practical interface-selection guidance beyond the basic catalog description.
CD4010CN - Hex Non-Inverting CMOS Buffer | onsemi
The onsemi CD4010CN is a monolithic six-element, non-inverting CMOS buffer with one bit per element, supplied in a 16-pin PDIP package. It operates from a single positive supply, uses complementary NMOS and PMOS enhancement-mode transistors, and provides output swings essentially equal to the supply voltage. The device is intended for logic-level buffering where multiple non-inverting outputs can isolate a source from downstream loads without changing logic polarity. A CMOS logic buffer belongs to the digital buffer and line-driver hierarchy, which sits between combinational logic ICs and interface circuits. The CD4010 family contains six independent buffer channels rather than gates with tied inputs and outputs. This arrangement allows each input to be connected directly to its corresponding output without inversion, making the device useful for fan-out, signal isolation, level-preserving distribution, and general-purpose logic interfacing. The key verified feature set includes six non-inverting elements, one bit per element, monolithic complementary MOS construction, and output operation close to the supply rails. Because each buffer provides an independent signal path, a circuit can use all six channels or leave unused inputs terminated according to the manufacturer's guidance. Its through-hole PDIP format is also appropriate for legacy industrial, control, instrumentation, and educational equipment where DIP sockets and hand or wave soldering remain common. Internally, the N-channel and P-channel enhancement-mode transistors form symmetrical CMOS stages. Complementary transistor action supports low static power in the switching state and rail-to-rail-style output behavior, although guaranteed output levels depend on the specified supply voltage and load current. The CD4010CN does not provide level translation between unrelated voltage domains by itself; its supply voltage and input thresholds must remain compatible with the source and load. Typical uses include buffering control signals between timing sections, driving multiple logic inputs from one source, isolating counter or flip-flop outputs, and preserving logic polarity in industrial control boards. The six independent stages can also support level-separated sections when the system uses one common supply. Designers should still account for input leakage, output drive current, propagation delay, fan-out, and unused-input behavior from the manufacturer datasheet. For a robust PCB layout, route each input and output directly to its corresponding pin, provide a stable supply-decoupling path near the device, and avoid long parallel traces where switching edges could couple noise between channels. Because the CDP package has long through-hole leads, observe the correct orientation and socket-pin numbering before energizing the circuit. This page combines verified product characteristics, drop-in replacement information, application guidance, and design cautions that are not presented together in the manufacturer datasheet.
CD40161B-MIL - CMOS Sync 4-Bit Binary Counter | Texas Instruments
The Texas Instruments CD40161B-MIL is a CMOS synchronous programmable 4-bit binary counter with asynchronous clear, supplied in a 16-lead hermetic dual-in-line ceramic package (F3A suffix) with a 3V to 18V supply range, a 5.5MHz typical maximum clock frequency at 5V, and a full military operating temperature range of -55C to +125C for high-reliability applications. A synchronous programmable counter is a digital sequential logic device that advances through a binary counting sequence on each rising clock edge while allowing any 4-bit value to be parallel-loaded via preset inputs. Within the logic IC hierarchy, counters are fundamental building blocks of the broader family of sequential logic and digital timing devices, sitting alongside shift registers and flip-flops as core building blocks for sequencing and frequency division in digital systems. Key features include fully static operation down to DC, standardized symmetrical output characteristics meeting JEDEC Tentative Standard No. 13B for B-series CMOS devices, and a fanout of 1 LSTTL load for direct interfacing with other logic families. The asynchronous clear resets all outputs to zero immediately regardless of clock state, and the ripple carry output enables straightforward cascading of multiple stages into wider counters. Technically, the CD40161B uses CMOS technology with buffered outputs and input protection diodes to VDD and VSS, providing low static power consumption and high noise immunity typical of the CD4000B series. Typical propagation delay is 160ns at 5V, and the device is functionally equivalent to and pin-compatible with the TTL 74LS161 counter. Typical applications include frequency dividers, programmable binary counting, counter control/timers, event counters, and state machines in industrial control, test equipment, and aerospace electronics where hermetic packaging and the military temperature range are mandatory. A key design consideration: tie the asynchronous clear input to VDD when unused to prevent spurious resets, and provide clean clock edges to avoid double counting. This page synthesizes verified datasheet parameters, drop-in family alternatives, pricing tiers, and practical design notes not consolidated in the manufacturer datasheet.
CD4017BE - CMOS Decade Counter/Divider, 16-PDIP | Texas Instruments
The Texas Instruments CD4017BE is a CMOS decade counter/divider with 10 decoded outputs, packaged in a 16-pin PDIP (through-hole). It operates as a 5-stage Johnson counter with built-in output decoding, advancing one position on the positive edge of the clock input, with active-high decoded outputs Q0-Q9 and a carry-out (CO) signal for cascading. The part is specified over a wide supply range of 3 V to 18 V and supports fully static operation with no minimum clock frequency. A decade counter/divider is a sequential logic circuit that counts clock pulses from 0 to 9 and then repeats, producing one decoded output pulse per count. Each of the 10 decoded outputs goes high in sequence, which makes the CD4017 useful as a one-of-N selector, a sequencer, or a frequency divider. In the broader hierarchy it belongs to the CMOS 4000 family of logic ICs, the standard for low-power, wide-supply-range digital functions. The "BE" suffix on TI parts denotes the plastic DIP package and the standard CMOS process. Key features of the CD4017BE include fully static operation (no minimum clock), typical operation up to 10 MHz at VDD = 10 V, medium-speed performance at 5 V and 10 V parametric ratings, low quiescent current tested at 20 V, and standardized symmetrical output characteristics. The output stage can source or sink several milliamps per pin, sufficient to drive LEDs directly in hobby circuits when current-limited by a series resistor. An active-high clock enable pin and a master reset (active-high) pin provide flexible control over counting and clearing. Architecturally, the CD4017 uses a 5-bit Johnson counter feeding a one-of-10 decoder. The Johnson-counter topology eliminates the race and glitch hazards associated with asynchronous ripple counters, because each stage is clocked synchronously. The carry-out signal goes high during counts 0-4 and low during 5-9, allowing two CD4017s to be cascaded to form a 100-state counter without external gating. Typical applications include LED chasers and running-light displays, frequency division, sequential timing, keypad scanning, and event counters. The wide 3 V to 18 V supply range lets designers power it directly from a 9 V battery, a 12 V rail, or a regulated 5 V logic supply without level shifting. The decoded outputs eliminate the need for an external binary-to-decimal decoder such as the CD4028, saving board space and cost. Design considerations for the CD4017 include input signal rise/fall time (slow edges near the clock threshold can cause double-counting), proper bypassing of VDD with a 100 nF ceramic capacitor close to the supply pin, and limiting LED current to the Absolute Maximum ratings when driving displays. Inputs must be brought below 0.5*VDD for a logic low and above 0.5*VDD for a logic high for reliable operation across the supply range. This page synthesizes distributor pricing from DigiKey, Mouser, and LCSC, plus cross-reference equivalents such as MC14017BCP and HCF4017BE drawn from JEDEC-registered CMOS 4000-series second sources - information not consolidated on the manufacturer datasheet alone.
CD4017BEE4 - CMOS Decade Counter/Divider, 10MHz, 16-PDIP | TI
The Texas Instruments CD4017BEE4 is a CMOS decade counter/divider that sequentially activates one of ten decoded outputs on each rising clock edge, housed in a 16-pin PDIP through-hole package. It operates from a 3 V to 18 V supply, supports fully static operation with a typical clock frequency of 10 MHz at VDD = 10 V, and is 100% tested for quiescent current at 20 V. It carries 5 V, 10 V, and 15 V parametric ratings and meets all requirements of JEDEC Tentative Standard No. 13-A for CMOS logic. A decade counter is a sequential logic device that advances through ten unique states per clock cycle, then automatically resets. The CD4017 belongs to the CD4000 series of CMOS logic ICs, sitting in the broader family of logic ICs, digital ICs, and ultimately semiconductors. This counter is widely used to convert a clock pulse train into a one-of-N sequential output, eliminating the need for a decoder circuit in many designs. Key features include five Johnson-counter stages with decoded 1-of-10 active-high outputs, an active-low carry-out for cascading multiple counters, a low clock-pulse count of ten per cycle, and fully static synchronous operation. Symmetrical output characteristics ensure consistent rise and fall times, and the device includes a clock-inhibit control and a master reset for flexible timing applications. Its wide supply range (3 V to 18 V) and CMOS low power make it a versatile general-purpose sequencing element. Architecturally, the CD4017BEE4 implements five D-type flip-flops arranged as a Johnson counter with built-in decode gating that produces ten mutually-exclusive active-high outputs. Each rising edge of the clock pin increments the internal state and shifts the active-high decode to the next output in sequence. A clock inhibit input disables counting without resetting state, while the master reset asynchronously clears all outputs and returns Q0 high. Typical applications include LED sequencer chasers, frequency division (divide-by-N), keyboard encoders, and decade counting displays. Its 10 MHz typical clock and 18 V rating also suit industrial control timing, hobby electronics, and educational digital logic training. When designing with the CD4017BEE4, place a 0.1 µF decoupling capacitor close to the VDD pin and a 1 µF to 10 µF bulk capacitor on the supply rail. Tie unused active-high outputs either to known states or through resistors, and observe the clock-inhibit setup time before re-enabling counting to avoid spurious counts. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
CD4018BF - CMOS Presettable Divide-By-N Counter | Texas Instruments
The Texas Instruments CD4018BF is a CMOS presettable divide-by-N counter built from five Johnson-counter stages, with buffered Q outputs and counter preset control gating. It operates from a 3 V to 18 V supply, provides medium-speed operation with a typical operating frequency of 10 MHz at a 10 V supply, and is supplied in a 16-lead ceramic dual-in-line package identified by the F package suffix. The CD4018BF is designed for applications requiring programmable frequency division, count sequencing, and asynchronous control of a counter stage. A CMOS presettable divide-by-N counter is a logic IC that divides an input clock by a selected count value. The CD4018B family contains five Johnson-counter stages, allowing each stage to be cascaded or selected for divide-by-N operation. Its buffered outputs and preset-control logic make it useful in digital timing, pulse-counting, sequencing, and clock-generation systems. The device sits within the hierarchy of CMOS counter logic, digital logic IC, and semiconductor electronics. The main performance features include medium-speed operation, fully static operation, standardized symmetrical output characteristics, and parametric ratings at 5 V, 10 V, and 15 V. The manufacturer datasheet states that quiescent current is tested at 20 V, and the maximum input current is 1 uA at 18 V. These characteristics support operation across low-voltage and higher-voltage CMOS logic systems while providing predictable static behavior. The counter includes clock, reset, set, and five buffered Q outputs, allowing the circuit to be used as a programmable divider or as part of a cascaded counter arrangement. The counter can be preset for a specific initial state and controlled by external logic, making it appropriate for repeatable timing sequences in industrial control, laboratory equipment, instrumentation, and embedded digital systems. Typical applications include pulse-generation circuits, programmable timing modules, digital waveform dividers, stepper-control sequencing, test and measurement systems, and general-purpose industrial counter boards. When designing with the CD4018BF, pay particular attention to clock transition requirements, reset and set pulse timing, unused input states, and the maximum supply voltage of 18 V. Decoupling close to the supply pins and clean clock routing are important for reliable operation in practical CMOS logic systems. This product page synthesizes the verified manufacturer and distributor information with practical application guidance, package details, and an explicit drop-in comparison. The CD4018BF is a legacy-style 16-pin CDIP counter, so engineers should confirm availability, lifecycle status, and equivalent sourcing before committing a new design to it.
CD4020BE - 14-Bit Ripple-Carry Counter | Texas Instruments
The Texas Instruments CD4020BE is a 14-bit CMOS ripple-carry binary counter and divider with a negative-edge-triggered clock input, operating from a single supply in a 16-pin plastic dual-inline package (16-PDIP). The counter advances one count on each high-to-low transition of the clock and provides 14 binary output stages for frequency division, timing, and event counting. An active-high reset allows the counting sequence to be cleared before a new operation. A ripple-carry binary counter is a type of sequential logic circuit that advances a binary count after each active clock edge. Its stages are connected in cascade, so propagation delay accumulates across the counter. This makes the CD4020BE suitable for simple divide-by-2^n and divide-by-2^(n+1) arrangements when the required output is the logical counter state rather than a high-speed synchronous binary word. The CMOS implementation places the device within the broader hierarchy of counter IC, digital logic IC, and semiconductor categories. The verified CD4020BE features include a single 14-bit counter element, negative-edge operation, 12 buffered outputs identified in the supplied comparison data, and a 16-PDIP package. The counter uses master-slave stages, helping prevent output changes while the clock is at its active level. Its divide-by-two output arrangement enables cascaded frequency division without requiring a separate binary-to-binary divider. The ripple architecture makes each successive output change after the clock transition because the carry propagates through the internal flip-flops. Designers should therefore use the appropriate decoded or single-stage output rather than treating Q13 and Q0 as a simultaneously updated binary bus. The package's through-hole format also supports prototyping, educational instruments, industrial control systems, and repair applications where PCB access and hand soldering are important. Typical uses include divide-by-16 or divide-by-4096 clock generation, periodic timer references, digital frequency division, industrial sequence counters, and embedded control logic. Because the counter responds to the negative clock edge, the source waveform, reset timing, and any downstream decoder must be checked to avoid counting an unintended transition. When laying out a new design, route the clock away from sensitive analog nodes and provide a clean return path. For reliable reset release, ensure the reset signal is inactive before the first intended clock edge. If the application requires simultaneous binary updates, a synchronous counter should be considered because ripple propagation delay can create intermediate output states. This page consolidates verified distributor information, pin-compatible counter alternatives, parameter comparisons, and practical design guidance. It helps engineers distinguish the CD4020BE from positive-edge counters and non-pin-compatible divider functions before committing to a PCB or production order.
CD4020BK - 14-Stage Binary Ripple Counter | Harris
Harris Corporation CD4020BK is a 14-stage, negative-edge-triggered ripple-carry binary counter and divider in a 16-pin flat-rail CFP package. The verified product data identifies one counter element, 14 counter bits, and a binary counter/divider function. Its RESET input returns the counter to the all-zero state, while each negative transition of the clock input advances the count. The input stage uses Schmitt-trigger action, allowing operation with slow or noisy clock transitions. A binary counter is a sequential logic device that stores and advances a binary number on each active clock transition. In the broader semiconductor hierarchy, the CD4020BK belongs to the counter and divider category, within CMOS logic ICs and digital logic. Its 14 internal stages can divide a periodic input by binary factors up to 2^14, subject to the operating conditions and propagation characteristics specified by the manufacturer. The verified distributor listing classifies CD4020BK as a 1-element, 14-bit, negative-edge-triggered counter in a 16-CFP package. The related manufacturer product information identifies the CD4020B family as a CMOS ripple-carry binary counter/divider. Each stage is described as a master-slave flip-flop, allowing the counter state to advance cleanly when the input clock undergoes a negative transition rather than reacting to both edges. Typical uses for this counter family include digital time-base generation, frequency division, programmable timing, clock-frequency reduction, and low-frequency waveform generation. The RESET function makes the device useful in sequential systems that require a defined starting state. The Schmitt-trigger clock input is particularly relevant when the source has a slow edge or transition disturbance, although external conditioning may still be needed in demanding EMI or high-noise environments. CD4020BK is identified with a military temperature grade and a flat, 16-terminal package. Because the supplied data does not state the exact supply-voltage range, operating-temperature limits, maximum clock frequency, output drive capability, or absolute maximum ratings, those values must be confirmed against the manufacturer datasheet before design release. Do not infer missing ratings from the CD4020B family without checking the applicable CD4020BK grade and package. This product-data page consolidates verified distributor pricing, package and counter details, functional comparisons, design guidance, and same-package replacement constraints. The comparison also distinguishes documented facts from unavailable electrical parameters, helping engineers make a qualification decision without converting family-level information into unsupported CD4020BK specifications.
