-2 Component - Unverified MPN | Datasheet Pending | XAIPART
The component with the bare MPN "-2" cannot be uniquely identified from the provided Verified Web Data and is not present in the XAIPART Internal Database. The query "-2 datasheet specifications price" returned generic datasheet-portal listings (DigiKey cross-reference, Datasheets.com, FindChips, AllDatasheet, OEMSTR), an Oracle Exadata X9M-2 server datasheet (unrelated), a Tesla Megapack product page (unrelated), a Dell standard price list (unrelated), and the Espressif ESP32 datasheet page (which surfaced due to "ESP32 Datasheet" matching the token "-2" only loosely). None of the returned URLs constitute a manufacturer product page or distributor listing for an electronic component whose manufacturer part number is literally "-2". Therefore no manufacturer brand, package, electrical ratings, or price tiers can be sourced from verified data for this identifier. Background context for engineers who encounter ambiguous short MPNs: an alphanumeric MPN (Manufacturer Part Number) is a unique identifier assigned by a semiconductor or passive-component manufacturer to a specific part, and it normally encodes a part family, a current/voltage/pin-count code, and a package/tolerance suffix. Two-character or single-character tokens such as "-2" almost always represent a fragment of a longer part number (for example, the trailing "-2" in "MAX232" or "LM358-N" strips) rather than a complete, orderable part. Resolving such a query requires the full MPN string from the device marking, the bill of materials (BOM), or the original schematic. How to proceed: enter the full MPN exactly as printed on the device or as listed in your BOM (e.g., "MAX232" not "232", "ATMEGA328P-AU" not "328P"), then re-query. Because the page cannot resolve a unique component, all numeric specs (operating voltage, output current, package pin count, thermal resistance, RoHS/AEC-Q100 status), pricing tiers, drop-in alternatives, pinout, and applications are intentionally marked [DATA_NEEDED] rather than guessed. This protects against fabricated content and lets the page be re-rendered the moment a valid MPN is supplied. Engineers are encouraged to consult the manufacturer datasheet, distributor parametric search (DigiKey, Mouser, Octopart), or the XAIPART site-search bar to look up the correct identifier.
54FCT162245CTEB - 16-Bit Bidirectional Transceiver, 5.5V, 48-CerPack | Renesas
The Renesas 54FCT162245CTEB is a 16-bit, high-speed, low-power bidirectional transceiver built on advanced dual-metal CMOS technology and housed in a 48-pin CERPACK (CERDIP-style sidebraze) ceramic package. It functions as either two independent 8-bit transceivers or one 16-bit transceiver, providing synchronous communication between two buses with 3-state outputs and a typical propagation delay of 4.5 ns at 50 pF load. The device operates across a 4.5 V to 5.5 V VCC range, with a wide -55 C to +125 C operating temperature window suited for military and aerospace programs. A bidirectional transceiver is a bus-interface IC that drives signals in either direction between two ports under the control of direction-control inputs, while 3-state outputs allow multiple devices to share a bus by entering a high-impedance state when disabled. The 54FCT162245CTEB belongs to the FCT (Fast CMOS Technology) logic family, positioned in the taxonomy as transceiver -> bus interface IC -> logic IC -> integrated circuit. It is engineered as a low-power CMOS replacement for legacy ABT (Advanced BiCMOS Technology) functions, delivering balanced drive strength (16 mA source/sink) with typical output skew below 250 ps for synchronous timing budgets. Key features include 16 mA balanced output drive on both ports, 500 uA typical quiescent supply current, Schmitt-trigger inputs for slow-edged or noisy signals, and an output-enable pin for each 8-bit half. ESD protection exceeds 2000 V per MIL-STD-883, Method 3015, and 200 V using the machine model. The device's 0.5 micron CMOS process yields the speed of bipolar ABT logic with a fraction of the power dissipation, simplifying thermal management in dense backplane designs. Architecturally, the transceiver uses dual-metal CMOS to achieve sub-5 ns propagation while keeping ICC low enough for portable instrumentation. Each 8-bit half is controlled independently: a DIR pin sets direction and an OE pin enables the outputs, so a single device can bridge two buses of different widths on the same PCB. Typical tSK(o) below 250 ps makes the part usable in clock-distribution and registered-buffer applications where edge alignment matters. Typical applications include military and aerospace backplanes, point-to-point board-to-board data buffering, 16-bit or 8-bit memory/address bus isolation, and synchronous inter-board communication in VME, cPCI, or custom parallel data links. The wide operating temperature range and ceramic hermetic package also suit downhole, avionics, and radiation-tolerant programs where plastic packages are not acceptable. When designing with this device, treat the CERPACK footprint as non-substitutable with plastic SOIC/DIP variants - any drop-in replacement must share the same 48-pin CERPACK land pattern. For new designs targeting commercial temperature ranges, consider the equivalent 74FCT162245T plastic-package family, but verify pinout compatibility before substitution. This page synthesizes distributor pricing, drop-in equivalents, and CERPACK-specific design notes that are not consolidated in the manufacturer datasheet alone.
74AHC00D118 - Quad 2-Input NAND Gate SOIC-14 | Nexperia
The Nexperia 74AHC00D118 is a quad 2-input NAND gate IC from the 74AHC (Advanced High-speed CMOS) logic family, packaged in a 14-pin SOIC (SOT108) with 2 channels of 2-input NAND per package. The device operates from a 2.0 V to 5.5 V supply and is fully specified over the -40 °C to +125 °C industrial temperature range, with a typical propagation delay of 7.5 ns at 5 V and 50 pF load, plus balanced 8 mA source/sink output drive and 2 µA quiescent current. The AHC family delivers TTL-compatible input thresholds at roughly one-third the quiescent power of legacy 74HC, enabling direct interface to 5 V microcontrollers and 3.3 V logic from a single rail. A NAND gate is one of the three elementary logic primitives (alongside AND and OR) from which any Boolean function can be constructed. The 74AHC00 implements the Boolean complement of AND: the output is logic-low only when both inputs are high. Because NAND and NOR are functionally complete, the 74AHC00 can be wired to build AND, OR, XOR, latches, SR flip-flops, and oscillators with the addition of discrete RC components. Within the 74-series taxonomy, the 74AHC00 sits between 74HC (HC MOS, low-power) and 74LVC (low-voltage CMOS, 1.65 V minimum), offering a speed/power balance tuned for 3.3 V and 5 V mixed-rail designs. Key differentiating features of the 74AHC00 include Schmitt-trigger inputs on all gates for slow or noisy edges, ±8 mA balanced output drive that can directly switch LEDs or small relays, 5 V tolerant inputs when powered from 3.3 V, and CMOS-compatible rail-to-rail output swing. JLCPCB records an input threshold range of 500 mV to 1.65 V (approximately VIL/VIH over the supply range) and a propagation delay of 7.5 ns at 5 V into 50 pF, making the part well suited to glue logic where propagation delay is acceptable up to tens of MHz. The 74AHC00 uses an advanced sub-micron CMOS process with internal ESD protection diodes on every pin and a standard CMOS totem-pole output structure. Designers should observe the 74-series input-voltage absolute maximum of 7 V even when VCC is below 5 V, and use a 0.1 µF ceramic decoupling capacitor within 5 mm of the VCC pin. The 14-SO (SOIC-14 narrow-body, JEDEC SOT108) package with its industry-standard pinout has remained unchanged for decades, allowing drop-in compatibility with HC, HCT, LVC, and AHC variants. Typical applications include 5 V microcontroller glue logic, oscillator and debouncer circuits, control logic in industrial PLCs and instrumentation, handheld battery-powered devices, and white-goods user-interface panels where a single SOIC-14 replaces multiple discrete gates. Designers appreciate the combination of TTL-compatible inputs, low quiescent current, and industrial temperature range when porting legacy 74HC designs to AHC for higher speed. When designing with the 74AHC00, observe CMOS handling precautions (ESD-sensitive; store in conductive foam) and add a 0.1 µF decoupling capacitor on VCC. For new 3.3 V-only designs, consider 74LVC00 for even lower power and wider VCC range; for 5 V-only legacy ports with TTL-threshold inputs, 74HCT00 is a closer electrical match. The page below synthesizes distributor pricing, drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet, helping engineers select and source the correct quad 2-input NAND gate quickly.
74AHC1G08SE-7 - Single 2-Input AND Gate, 2V-5.5V, SOT-353 | Diodes Inc
The Diodes Incorporated 74AHC1G08SE-7 is a high-speed CMOS single 2-input positive AND gate with a standard push-pull output stage, housed in a 5-pin SOT-353 surface-mount package. It is specified for operation across a 2.0V to 5.5V supply range, with a typical propagation delay of 16 ns and 8 mA DC output current capability per channel. The device is fabricated using silicon-gate CMOS technology and is part of Diodes Incorporated's AHC (Advanced High-speed CMOS) logic family. A logic gate is a fundamental building block of digital electronics that performs a Boolean function on one or more binary inputs to produce a single binary output. The AND gate is one of the three primitive Boolean operators (along with OR and NOT) from which all other digital logic functions can be constructed. CMOS (Complementary Metal-Oxide-Semiconductor) logic gates use paired p-channel and n-channel MOSFETs to achieve very low static power consumption while delivering high noise immunity. Within the logic hierarchy, the AHC family sits between standard HC (High-speed CMOS) and the faster AHCT (AHC with TTL-compatible inputs) families, balancing speed, drive strength, and power consumption for general-purpose digital design. Key features of the 74AHC1G08SE-7 include CMOS-compatible input switching thresholds, balanced output drive with ±8 mA source/sink capability at 4.5V VCC, low quiescent current, and ESD protection per industry-standard methods. The SOT-353 (also called SC-88A or SC-70-5 in some product lines) is a compact 5-lead surface-mount package that occupies approximately 2.0 mm × 2.0 mm of PCB area, making this part ideal for space-constrained portable and handheld designs. The SE-7 suffix indicates tape-and-reel packaging for high-volume assembly. Typical applications include general-purpose digital logic glue, signal gating and clock-enable functions, microcontroller I/O expansion, level translation interfaces between logic domains, and pull-up/pull-down replacement networks. The wide 2V–5.5V supply tolerance allows direct interfacing with 3.3V microcontrollers, 5V legacy logic, and battery-powered systems. When designing with this part, observe standard CMOS handling precautions: unused inputs must be tied to VCC or GND (never left floating) to prevent shoot-through current and to keep quiescent supply current at its rated low level. The SOT-353 thermal resistance and small pad geometry make it well-suited for reflow-soldered hand assemblies and high-density boards.

74AHC1G17GVH - Single Schmitt-Trigger Buffer SC-74A | Nexperia
The Nexperia 74AHC1G17GVH is a single-gate, non-inverting buffer with Schmitt-trigger inputs, fabricated in advanced CMOS AHC logic technology and housed in a 5-pin SC-74A (SOT-753/TSOP-5) surface-mount package. The device operates from a 2.0 V to 5.5 V VCC supply, supports CMOS-level inputs (with TTL-compatible variants in the 74AHCT1G17 family), and features overvoltage-tolerant inputs that enable use as a translator in mixed-voltage environments. The Schmitt-trigger input hysteresis ensures clean, jitter-free output transitions on slowly rising or noisy input edges, making the part well-suited to button debouncing, line conditioning, and clock/pulse shaping. A Schmitt-trigger buffer is a single-input, single-output logic gate whose input switching threshold includes deliberate hysteresis — the input trips at a higher voltage on the rising edge than on the falling edge. This suppresses noise-induced oscillation and produces a single, clean output edge even when the input signal is slow, noisy, or has significant ringing. Buffers (as opposed to inverters) simply re-create the input logic level with greater drive strength, isolating a sensitive source from a noisy load, or providing level translation between two voltage domains. The 74AHC1G17 sits within the logic IC hierarchy: logic gate -> combinational logic -> standard logic IC -> semiconductor IC. Key features of the 74AHC1G17GVH include ±8 mA balanced output drive at 5 V, low quiescent current, fast propagation delay, and overvoltage-tolerant inputs. The SC-74A package measures only 2.9 x 1.5 x 1.0 mm with a gull-wing lead frame compatible with standard SMD assembly. The 1G family designation indicates a single-gate part optimized for footprint-sensitive designs where multi-gate packages would waste board area. Typical applications include signal conditioning in industrial control, button/keyboard debouncing, level shifting between 3.3 V and 5 V rails, clock/pulse shaping in microcontroller I/O expansion, and general-purpose logic glue in mixed-signal systems. The wide 2.0-5.5 V operating range and CMOS/TTL input flexibility make it a versatile building block across consumer, industrial, and automotive subsystems. When designing with this part, ensure input edges are not faster than the datasheet-specified rise/fall limits and respect the absolute maximum VCC of 6 V to avoid latch-up.

74CB3Q3257BQX - 4-Bit SPDT FET Bus Switch, 5V | Nexperia
The Nexperia 74CB3Q3257BQX is a quad high-bandwidth, single-pole double-throw (SPDT) FET bus switch with 4 channels, organized as four 2:1 muxes/demuxes in a 16-pin DHVQFN (2.5x3.5 mm) SOT763 package. It uses an integrated charge pump to bias the NMOS pass-transistor gates above VCC, yielding a low and flat on-resistance of approximately 4 ohm across the signal range while enabling 5 V signal switching from a 2.3 V to 3.6 V supply. The device is pin-compatible with TI's SN74CB3Q3257 in the same BQQ package footprint. A FET bus switch (also called a bus multiplexer/demultiplexer) is a passive analog switch implemented with parallel NMOS transistors whose gates are driven by an internal charge pump. Unlike mechanical or relay switches, FET switches have no moving parts, offer nanosecond switching speeds, draw zero quiescent current through the signal path, and present a near-ideal connection when ON. They sit in the hierarchy: signal switch -> analog switch -> multiplexer/demultiplexer -> logic IC -> semiconductor. Key features include 4 ohm typical on-resistance, 200 MHz bandwidth, undershoot-protection diodes on I/Os, partial-power-down support via Ioff circuitry, and standard CMOS inputs with TTL-compatible switching thresholds. A single select input (S) routes each of the four channels, while an active-high output enable (OE) places all channels in high-impedance when asserted. The DHVQFN-16 package provides an exposed thermal pad and is qualified to -40 C to +85 C operation. Typical applications include USB 2.0/3.0 port switching, I2C/SPI/UART signal multiplexing, HDMI/DVI link switching, server hot-plug routing, and general-purpose high-speed signal gating. The wide 2.3 V to 3.6 V supply range and 5 V tolerant I/Os make the 74CB3Q3257BQX well suited for mixed-voltage board designs where signals exceed the local supply rail. When designing with this part, place decoupling capacitors as close as possible to VCC and treat the exposed pad as a thermal/ground stitch to the inner PCB ground plane. Note that signal paths are unidirectional in terms of bandwidth optimization; for true bidirectional analog signals use a true analog switch variant. Always confirm output-enable logic polarity before board bring-up.

74CBTLV3125BQ - 4-Bit Bus Switch DHVQFN-14 | Nexperia
The Nexperia 74CBTLV3125BQ is a 4-bit high-speed CMOS bus switch featuring separate active-high output-enable inputs (1OE to 4OE) per channel, housed in a 14-pin DHVQFN (2.5 x 3 mm) exposed-pad package (SOT762). It operates from a 2.3 V to 3.6 V supply, with a nominal 3.3 V VCC rail, and provides four independent 1:1 (SPST) FET switches with very low on-state resistance (typically 5 ohm) and minimal propagation delay. A bus switch (also known as an FET switch or analog switch) is a CMOS pass-transistor device that uses parallel N-channel and P-channel MOSFETs to connect or isolate two digital buses without buffering or level shifting. Bus switches sit in the digital logic family (logic ICs -> signal switches -> bus switches) and are widely used to route high-speed signals (PCIe, USB, memory buses) between sources when full multiplexer functionality is not needed. Their low on-resistance preserves signal integrity, while the high-impedance OFF state isolates segments to prevent contention during hot-swap or power-domain transitions. The 74CBTLV3125BQ delivers four independent switches with near-zero propagation delay, support for rail-to-rail signal passing, and an output enable per channel for granular control. The DHVQFN-14 package includes an exposed die attach pad that lowers thermal resistance to roughly 50 C/W and provides a low-inductance ground return. The device is specified over the -40 C to +125 C automotive temperature grade and is qualified for hot-swap / live-insertion applications where pre-charged bus capacitance must not disturb downstream logic. Typical end-use applications: DDR memory bank switching on motherboards, hot-swappable I/O cards, PCIe signal routing, I2C / SMBus voltage-rail isolation, and point-of-load rail multiplexing. The wide operating range also supports industrial 24 V bus systems via external resistor networks when paired with upstream protection. When designing with this part, place input and output traces symmetrically and maintain continuous ground returns under the exposed pad. Each OE pin has internal weak pull-up; tie any unused OE to VCC for permanent enable, never leave it floating.
74HC165D - 8-Bit Parallel/Serial-In Shift Register | Nexperia SOIC-16
The Nexperia 74HC165D is a high-speed CMOS 8-bit parallel-load or serial-in shift register with complementary serial outputs (Q7 and Q7-bar), housed in a 16-pin SOIC (SOT109-1) package. The part accepts asynchronous parallel data on D0-D7 when SH/LD is low, then shifts the captured word out serially through Q7/Q7-bar on each rising CLK edge. Operating voltage spans 2.0 V to 6.0 V, with TTL-compatible CMOS inputs and standard CMOS outputs. The 74HC165 belongs to the 74HC logic family of high-speed Si-gate CMOS devices, which are pin-compatible with low-power Schottky TTL (LSTTL) and specified per JEDEC standard no. 7A. As a parallel-in/serial-out (PISO) shift register, it is one of the most common building blocks for I/O expansion: it converts 8 parallel inputs into a single serial data stream, freeing microcontroller GPIOs. It sits in the broader hierarchy of logic ICs -> PISO shift registers -> serial-to-parallel/parallel-to-serial converters -> digital logic. Key features include an asynchronous 8-bit parallel load (SH/LD), a synchronous serial input (DS), two complementary serial outputs (Q7 and Q7-bar) for flexible daisy-chaining, and standard CMOS output drive capability. The MSI (Medium-Scale Integration) ICC category gives typical quiescent current around 8 uA, and the wide 2-6 V supply range allows drop-in use in both 3.3 V and 5 V logic designs. The device is also available in the 74HCT165 variant for TTL-level input compatibility. Internally, the 74HC165D uses a master-slave flip-flop architecture implemented in silicon-gate C2MOS technology, achieving propagation delays comparable to LSTTL while consuming CMOS-level quiescent power. The asynchronous parallel load is edge-controlled by SH/LD, decoupled from the shift clock, which simplifies firmware because the host does not have to clock the load bit. The two complementary outputs Q7 and Q7-bar eliminate the need for an external inverter when chaining multiple devices for 16-, 24-, or 32-bit expansion. Typical applications include expanding microcontroller GPIO for button/keypad matrices, reading multiple switch inputs over SPI-like bit-banging, driving LED chains from a small pin-count MCU, scanning industrial sensors, and building shift-register-based input multiplexers in PLC and HMI systems. The wide supply range and CMOS power profile also make it suitable for battery-powered IoT peripherals. When designing with the 74HC165D, place a 100 nF decoupling capacitor close to VCC, and remember that the parallel-load inputs D0-D7 are sampled asynchronously when SH/LD goes low. For multi-device daisy chains, tie the Q7-bar output of stage N into the DS input of stage N+1, and clock all SH/LD and CLK lines in parallel to keep the load deterministic. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet alone.
74HC165D,652 - 8-Bit Parallel-In/Serial-Out Shift Register | Nexperia
The Nexperia 74HC165D,652 is an 8-bit serial or parallel-in/serial-out shift register from the 74HC high-speed Si-gate CMOS logic family, housed in a 16-pin SOIC (SOT109-1) package. It supports asynchronous 8-bit parallel loading through D0-D7 inputs and synchronous serial shifting, with two complementary serial outputs (Q7 and Q7-bar). The device operates over a 2 V to 6 V supply range and is specified in compliance with JEDEC standard no. 7A, while remaining pin-compatible with Low-power Schottky TTL (LSTTL). A shift register is a sequential logic device that converts between serial and parallel data formats, sitting in the broader hierarchy of digital logic ICs, specifically the registers, latches, and counters category. The 74HC family uses silicon-gate CMOS technology to deliver TTL-compatible logic levels with substantially lower power consumption than bipolar LSTTL, making it the industry workhorse for glue logic, I/O expansion, and display/keypad scanning subsystems where a microcontroller lacks sufficient native GPIO pins. Key features include a wide 2 V to 6 V operating supply, asynchronous parallel load via the SH/LD-bar pin, clock inhibit input, complementary Q7/Q7-bar outputs for cascading, and serial data input (DS) for daisy-chaining multiple devices. The HC variant provides CMOS input switching levels with low quiescent current, and the part is specified from -40 °C to +125 °C across the industrial operating range. Propagation delays are typically in the low tens of nanoseconds at 6 V, sufficient for MCU-driven peripheral scanning at hundreds of kilohertz. The device uses a master shift register plus a parallel load register architecture controlled by SH/LD-bar. When SH/LD-bar is LOW, the asynchronous parallel inputs D0-D7 are clocked into the shift register; when HIGH, the device shifts serial data on each rising edge of the clock. The complementary Q7 and Q7-bar outputs enable direct cascading without external inverters, simplifying design of multi-byte shift chains. Typical applications include microcontroller I/O expansion, keypad scanning matrices, LED driver multiplexing, input multiplexing for analog signals, and reading multi-position DIP switches or rotary encoders. The parallel-load capability makes it especially useful when many inputs must be sampled simultaneously rather than sequentially. When designing with this part, place 0.1 µF decoupling close to VCC and observe CMOS static-discharge handling because the parallel data inputs and clock pins are sensitive to ESD. Ensure that SH/LD-bar timing meets the minimum pulse-width specification in the manufacturer datasheet to avoid corrupted parallel loads. This page consolidates verified distributor pricing, drop-in SOIC-16 alternatives, application notes, and design guidance for the 74HC165D,652 that engineers typically piece together from multiple sources.
74HC165D,653 - 8-Bit Parallel-In/Serial-Out Shift Register | Nexperia
The Nexperia 74HC165D,653 is an 8-bit parallel-in/serial-out (PISO) shift register from the HS Si-gate CMOS family, housed in a 16-pin SOIC (SOT109-1) package. It supports asynchronous parallel loading and synchronous serial shifting, with two complementary serial outputs (Q7 and Q7-bar) and operates from a 2 V to 6 V supply. According to the Nexperia datasheet, the device complies with JEDEC standard no. 7A and is pin-compatible with Low-power Schottky TTL (LSTTL), enabling drop-in replacement of legacy 74LS165 logic in existing footprints. A shift register is a sequential logic device that converts data between parallel and serial formats, used to expand the number of input or output pins available on a microcontroller. Within the broader taxonomy, a PISO shift register sits inside the shift register category, which is a subclass of sequential logic ICs, which itself belongs to the integrated circuit family and ultimately the semiconductor hypernym. The 74HC165 specifically enables one-directional parallel-to-serial conversion, complementing the 74HC595 (serial-to-parallel) to form a complete GPIO-expansion pair using only a few microcontroller pins. Key features include a wide 2 V to 6 V supply range, ±5.2 mA output drive capability, 6 ns typical propagation delay at 5 V, and asynchronous parallel load control via the SH/LD pin. The clock-inhibit (CLK INH) function allows the user to freeze the shift state while continuing to clock the device, simplifying state-machine implementation. A serial data input (DS) permits cascading of multiple 74HC165 ICs to build arbitrarily wide input shift registers, and the complementary Q7 output provides a wired-OR option without external inversion. Architecturally the part uses a high-speed Si-gate CMOS process that delivers LSTTL-equivalent drive strength at roughly an order of magnitude lower quiescent current. The internal design features eight master-slave flip-flops clocked by the rising edge of CP, with a parallel-load multiplexer controlled by the active-low SH/LD pin. When SH/LD is LOW, data on D0 through D7 is asynchronously loaded; when SH/LD is HIGH, the rising edge of CP shifts the register one position toward Q7. Power dissipation is dominated by dynamic switching losses and remains well below 1 mW quiescent at room temperature. Typical applications include multi-input button-debounce and keypad scanning matrices, parallel sensor data acquisition over a single SPI/MCU pin, expanding microcontroller input count in industrial control panels, reading 7-segment multiplexed displays with limited GPIO, and shift-register multi-channel scanning for security keypads. Designers commonly cascade two or three 74HC165 ICs to read 16 or 24 inputs using only four microcontroller pins. When designing with this part, place a 100 nF decoupling capacitor as close as possible to the VCC pin, keep the SH/LD and CP traces short to avoid ground-bounce-induced false clocking, and use a Schmitt-trigger buffer on the clock line if routing exceeds 50 mm. Note that the 74HCT variant is required when interfacing to 5 V TTL logic from a 3.3 V microcontroller. This page synthesizes distributor pricing, drop-in alternatives from multiple manufacturers, application-specific design notes, and a parametric comparison not assembled in any single manufacturer datasheet, providing actionable information for both procurement and design engineering teams.
74HC2G17GW - Dual Non-Inverting Schmitt Trigger, 6-TSSOP | Nexperia
The Nexperia 74HC2G17GW is a high-speed Si-gate CMOS dual non-inverting Schmitt-trigger buffer housed in a 6-pin TSSOP (SOT363 / SC-88) package. Each of the two channels accepts slowly changing input signals and converts them into sharply defined, jitter-free output signals, with a typical propagation delay of around 10 ns at 5 V VCC. The device operates from a 2.0 V to 6.0 V supply, supports ±5.2 mA output drive capability, and tolerates input signals up to VCC plus 0.5 V thanks to integrated input clamp diodes. A Schmitt trigger is a comparator-style input stage with two distinct switching thresholds - a higher threshold (VT+) for the rising edge and a lower threshold (VT-) for the falling edge. The hysteresis between these thresholds (typically 1.0 V at 5 V VCC for the 74HC2G17) rejects noise, ringing, and slow edges, producing clean digital transitions where a standard CMOS gate would oscillate. Within the broader taxonomy, this device is a logic buffer - a sub-category of interface ICs that sits between drivers and receivers, all of which fall under the umbrella of standard logic ICs and ultimately digital semiconductors. Key features include CMOS Schmitt-trigger inputs with input hysteresis, push-pull complementary outputs capable of sourcing and sinking ±5.2 mA, a maximum quiescent current in the microamp range, and ESD protection on all inputs. Inputs include clamp diodes that enable the use of current-limiting series resistors when interfacing to voltages above VCC, simplifying mixed-voltage designs. The device is specified over the -40 °C to +125 °C automotive/industrial temperature range. The 74HC2G17GW uses a high-speed CMOS Si-gate process that delivers TTL-compatible logic levels on the HC version and true TTL levels on the HCT variant (74HCT2G17GW). The push-pull output stage eliminates the need for external pull-up resistors and avoids the static power dissipation of open-drain alternatives. With two independent buffers in a 6-pin package, the part is a compact building block for signal conditioning, line receivers, and oscillator circuits. Typical applications include debouncing mechanical switches and push-buttons, conditioning slow analog signals before they reach a microcontroller, square-wave relaxation oscillators using an RC network, and rising-edge/pulse shaping in industrial control and automotive body electronics. The wide supply range and TTL-compatible thresholds make it a flexible interface between legacy 5 V logic and modern 3.3 V microcontrollers. When designing with this device, place a 0.1 µF decoupling capacitor as close as possible to the VCC pin and ensure that input rise/fall times remain slow enough that the Schmitt hysteresis is meaningfully larger than the input noise. Inputs that exceed VCC by more than one diode drop (~0.7 V) must be current-limited to within the absolute maximum rating. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single reference for footprint-compatible parts and selection trade-offs.
74HC4040BQX - 12-Stage Binary Ripple Counter | Nexperia
The Nexperia 74HC4040BQX is a 12-stage binary ripple counter IC housed in a 16-pin DHVQFN (SOT763) leadless package measuring 2.5x3.5 mm. It is part of the high-speed Si-gate CMOS 74HC logic family and is pin-compatible with the legacy HEF4040B series, conforming to JEDEC standard no. 7A. The device advances its count on the HIGH-to-LOW transition of the clock input (CP) and provides twelve parallel buffered outputs (Q0 through Q11) for direct binary decoding. A binary counter, also called a ripple counter or divide-by-N counter, is a sequential logic circuit formed by cascading toggle flip-flops. Each stage divides the previous stage's frequency by two, producing output frequencies of fCLK/2, fCLK/4, ... fCLK/4096 at Q0..Q11. Ripple counters sit within the broader hierarchy of digital logic -> sequential logic -> counters -> frequency dividers -> clock-generation circuits, and remain widely used for low-cost timing, event-counting and watchdog applications where synchronous operation is not required. Key features of the 74HC4040BQX include an asynchronous master reset (MR) input that asynchronously clears all twelve stages and forces all outputs LOW regardless of CP state, wide operating voltage range of 2.0 V to 6.0 V, typical propagation delay of a few nanoseconds per stage, and low quiescent current. The 74HC variant accepts standard CMOS input levels while the pin-compatible 74HCT4040 variant supports TTL-level inputs for mixed-logic interfaces. Architecturally, each counter stage is a static toggle flip-flop that ripples carry from the previous stage's Q output to the next stage's clock input. This asynchronous topology limits the maximum usable clock frequency for long count chains because the cumulative delay adds as the count propagates, but for divide-by-4096 applications at modest frequencies the device is more than adequate. Typical applications include frequency division and clock generation, event/timeout counters, watchdog timers, binary address scanning in LED or relay driver chains, and waveform synthesis. Designers also use the 74HC4040 family to derive sub-system timing from a master oscillator or microcontroller clock. A key design consideration with ripple counters is the asynchronous nature of the carry - outputs do not change simultaneously and glitches may be present on intermediate outputs during transitions. For designs requiring glitch-free synchronous division, a synchronous counter such as the 74HC161 family is preferred. The MR reset is asynchronous and must be debounced in noisy environments.

74HC4052D - Dual 4:1 Analog Mux/Demux, 16-SOIC | Nexperia
The Nexperia 74HC4052D is a dual single-pole quad-throw (2 x SP4T) analog switch suitable for analog or digital 4:1 multiplexer/demultiplexer applications, housed in a 16-pin SOIC (SOT109-1) package. Key specifications include a low ON resistance of approximately 150 ohm, an operating supply voltage range of 2 V to 10 V for the VCC rail, and a wide analog signal swing from VEE to VCC (up to 10 V peak-to-peak). The device includes two independent 4-channel switches with a common digital select interface, supporting both multiplexing and demultiplexing operations in a single package. A 74HC-series analog multiplexer is a CMOS logic device that routes one of several analog input signals to a common output line, or vice versa. The 74HC4052 is part of the 4000-series analog switch family, hierarchically classified as an analog switch -> multiplexer/demultiplexer -> interface IC -> integrated circuit. These devices serve as fundamental building blocks in mixed-signal systems, enabling microcontrollers with limited I/O to sample multiple analog channels through a single ADC input, or to drive multiple loads from a single DAC output. The 74HC prefix indicates high-speed CMOS logic with TTL-compatible input thresholds, while the 4052 designation identifies the dual 4:1 channel configuration. Key differentiating features include very low power consumption (CMOS quiescent current typically in the nanoampere range), built-in ESD protection per HBM (Human-Body Model) standards, and break-before-make switching that prevents momentary shorting between adjacent channels during transitions. The 16-SOIC package provides a standardized industrial footprint with a typical thermal resistance of approximately 75 C/W and supports surface-mount reflow soldering. The part is qualified to operate over the automotive temperature grade of -40 C to +125 C. The 74HC4052D utilizes a transmission-gate architecture built from parallel NMOS and PMOS transistors, achieving near-constant ON resistance across the analog signal range and minimal distortion for audio-frequency signals. The digital control inputs (A, B, and an active-low enable) are TTL-compatible at 5 V VCC, allowing direct connection to microcontrollers and standard logic families without level shifters. The wide VEE to VCC signal path allows the device to handle bipolar analog signals when VEE is biased below ground, a critical feature for instrumentation and audio applications. Typical applications include analog signal routing in data acquisition systems, audio source selection in consumer electronics, sensor multiplexing in IoT devices, video signal switching, and industrial process control. The combination of low ON resistance, low crosstalk, and wide bandwidth (typically 100 MHz at -3 dB) makes the part suitable for both DC precision signals and high-frequency analog routing. When designing with the 74HC4052D, observe the absolute maximum ratings: VCC must never exceed 10 V (or per datasheet VCC - VEE must remain within the absolute maximum differential). Place 100 nF decoupling capacitors as close as possible to the VCC and VEE pins to suppress digital switching noise from coupling into the analog signal path. Add 10 kohm pull-up resistors on the enable pin if hard-wired always-on operation is desired. This page synthesizes distributor pricing, cross-brand drop-in alternatives, and PCB layout guidance not found in the manufacturer datasheet, helping procurement and design engineers select and source the 74HC4052D with confidence.
74HC7014D - Hex Non-Inverting Precision Schmitt-Trigger | Nexperia
The Nexperia (formerly NXP/Philips) 74HC7014D is a hex non-inverting buffer with precision Schmitt-trigger inputs, specified in compliance with JEDEC standard no. 7A and housed in a 14-pin SO (SOT108) package. Each of the six channels is a 1-bit buffer element with push-pull output drive, providing standard CMOS output capability across the 3 V to 6 V operating voltage range. A Schmitt trigger is a comparator-based input stage that uses two distinct threshold voltages—one for rising edges (V_T+) and one for falling edges (V_T−)—producing a hysteresis band that prevents oscillation on slow or noisy input transitions. In the 74HC7014, these trigger levels are precisely defined at 0.55 × V_CC (V_T−) and 0.65 × V_CC (V_T+), yielding a tight 10% hysteresis window centred on V_CC/2. This precision distinguishes the 74HC7014 from general-purpose 74HC inverters (74HC04) and gates, whose thresholds vary more widely with V_CC and temperature. Key features of the 74HC7014D include high-speed Si-gate CMOS construction, low power dissipation typical of 74HC family logic, full push-pull totem-pole outputs capable of sourcing and sinking symmetric load current, and the JEDEC 7A-specified DC characteristics that guarantee interoperability with other HC-family devices. The device is pin-compatible with the 74HC04 hex inverter family footprint (14-SO/SOIC-14) but offers non-inverting transfer function with defined hysteresis. Typical applications include signal conditioning for slowly-rising sensor or mechanical-switch inputs, line receivers in noisy industrial environments, oscillator circuits (the Schmitt trigger hysteresis is the core element of relaxation oscillators), debouncing of mechanical switch contacts, and waveform shapers for clock-recovery or threshold-detection circuits. Because the trigger band tracks V_CC proportionally, the 74HC7014 also functions well as a voltage-level detector when V_CC is used as the reference. When designing with this device, observe standard CMOS handling practices (ESD protection) and ensure output loading stays within the standard HC output capability (typically ±4 mA at 6 V). For automotive or extended-temperature applications the Q100/J version is available in the same SO-14 package, providing pin-compatible migration without PCB changes.
74HCT154BQ - 4-to-16 Line Decoder/Demultiplexer DHVQFN-24 | Nexperia
The Nexperia (formerly NXP Semiconductors) 74HCT154BQ is a 4-to-16 line decoder/demultiplexer fabricated in high-speed Si-gate CMOS technology, packaged in a 24-pin DHVQFN (SOT815-1, 5.5 mm x 3.5 mm) surface-mount package. It accepts four active-HIGH binary weighted address inputs (A0 to A3) and drives sixteen mutually exclusive active-LOW outputs (Y0 to Y15), making it well suited to memory chip-select decoding, address demultiplexing, and discrete LED/relay driver expansion. The device is specified per JEDEC standard no. 7A and is pin-compatible with Low-power Schottky TTL (LSTTL). Background knowledge: A decoder/demultiplexer is a combinational logic device that converts a small binary address into one of many mutually exclusive outputs. It belongs to the broader category of digital logic ICs, and within that category to the encoder/decoder/multiplexer/demultiplexer sub-family. In a typical digital system hierarchy, decoders sit between the processor/control logic and the peripheral devices they enable, providing one-hot selection signals such as memory chip-select, peripheral enables, or display-row selects. The 4-to-16 decoder is one of the most commonly used building blocks for memory and I/O expansion on legacy buses. Key features of the 74HCT154BQ include two active-LOW enable inputs (E1 and E2) that can be used together as a strobe to eliminate normal address-decoding glitches on the outputs, a wide 4.5 V to 5.5 V supply range (HCT logic level, TTL-compatible inputs), CMOS output drive capability, and standardized input hysteresis for improved noise immunity in industrial environments. The two enable gates can also be cascaded to form a 5-to-32 decoder using two 74HCT154 devices, an important pattern for memory expansion beyond 16 devices. Typical applications include memory chip-select decoding for systems with up to 16 memory or peripheral devices, address demultiplexing for legacy microprocessor address buses (such as 8085, Z80, 6800), LED matrix row/column driving, relay and solenoid driver expansion, and general-purpose one-of-N selection in industrial control logic. The enable-strobe feature is particularly valuable when the device feeds asynchronous logic that would otherwise propagate decoding glitches. When designing with this part, pay attention to the active-LOW output polarity (Y outputs sink current when selected) and unused enable pins must be tied to their active state. The DHVQFN-24 package provides a low thermal resistance path and requires thermal vias under the exposed pad for reliable operation; ensure the pad is soldered to a sufficient copper area on the PCB. All inputs include clamp diodes so input voltages should be constrained within the supply range.
74HCT1G04GW - Single Inverter Gate, 5-TSSOP | Nexperia
The Nexperia 74HCT1G04GW is a single high-speed Si-gate CMOS inverter housed in a 5-pin TSSOP (SOT353/UMT5) surface-mount package. Operating from a 4.5 V to 5.5 V supply, the device delivers TTL-compatible input switching thresholds while consuming CMOS-level quiescent current, making it ideal for level translation between 5 V TTL logic and 3.3 V CMOS rails in mixed-voltage systems. What is a single-gate logic IC? A single-gate logic IC is a minimal-footprint logic function packaged in a small-outline surface-mount package (typically 5 to 6 pins). It belongs to the logic IC hierarchy: inverter -> gate -> combinational logic -> standard logic family. Single-gate devices occupy a single logic function on one die, enabling designers to place a single inverter, buffer, OR, AND, or Schmitt-trigger function exactly where it is needed on a board without paying the area or cost of a quad-gate or hex-gate package. Compared with discrete BJT/MOSFET inverter circuits, single-gate CMOS ICs offer matched propagation delays, balanced rise/fall times, ESD-rated inputs, and predictable output impedance across the full operating temperature range. Key features of the 74HCT1G04 include a wide supply voltage range, symmetrical output impedance, ESD protection on every input, balanced propagation delays, and very low power dissipation. Inputs include clamp diodes that allow current-limiting resistors to interface inputs to voltages exceeding VCC, simplifying mixed-voltage designs without external protection. Architecturally, the 74HCT1G04 uses an HCT sub-family CMOS process: the input stage accepts TTL logic levels (VIL <= 0.8 V, VIH >= 2.0 V) while the output stage swings rail-to-rail CMOS levels. This makes the HCT variant the bridge between legacy 5 V TTL peripherals and modern CMOS controllers. The standard output current is half that of the larger 74HCT04 hex inverter, but for a single logic inversion this is rarely a constraint. Typical applications include signal inversion in microcontroller I/O lines, bus signal conditioning, level translation between 5 V and 3.3 V logic domains, reset-signal inversion, and clock-signal polarity reversal. Designers also use it to debounce mechanical switches when combined with an RC network. The 5-pin TSSOP footprint keeps the inverter within a few square millimeters of board area, ideal for high-density PCB layouts and signal-integrity sensitive traces. When designing with this part, place a 0.1 uF decoupling capacitor as close as possible to the VCC pin, keep the input trace short to minimize capacitive loading, and verify that the driving source can supply at least 1 mA through the input clamp diode if input voltages can exceed VCC during hot-plug or fault conditions. This page consolidates distributor pricing for the 74HCT1G04GW, 5-TSSOP drop-in alternatives from Nexperia and TI, and engineering design notes that complement the manufacturer datasheet.
74HCT1G04GW-Q100H - Single Inverter, 5-TSSOP, AEC-Q100 | Nexperia
The Nexperia 74HCT1G04GW-Q100H is a single inverter gate in the 74HCT logic family, qualified to AEC-Q100 Grade 1 for automotive applications, housed in a 5-pin TSSOP (SOT353-1 / UMT5) package. The "HCT" suffix indicates high-speed CMOS with TTL-compatible input thresholds, allowing direct interfacing with TTL-level signals while preserving CMOS-like output levels, noise margins, and quiescent current. Operating across a 2.0 V to 5.5 V VCC range with typical propagation delay around 6 ns at 4.5 V, it suits clock-conditioning, reset inversion, and signal-level translation in mixed-logic boards. A single inverter, also called a NOT gate, is the most fundamental combinational building block in digital logic. It flips the logical state at its output - a logic-low at the input yields a logic-high at the output, and vice versa. Inverter gates form the foundation for NAND, NOR, XOR, and oscillator circuits when combined with other primitives. The 74HCT1G series in particular integrates one gate into an ultra-small SOT353 / SC-88 footprint, providing complete logic functions at minimal board area. The -Q100 suffix denotes full AEC-Q100 Grade 1 qualification, suiting under-hood automotive environments with extended thermal stress. Key features of this part include ±2 mA balanced output drive at 4.5 V, input clamp diodes that allow current-limiting resistors to interface inputs to voltages exceeding VCC, very low quiescent supply current, and stable operation across -40 °C to +125 °C. Inputs tolerate 5 V even when VCC is unpowered, simplifying mixed-voltage designs. CMOS output stages produce rail-to-rail swings, eliminating the V_OL/V_OH gap that plagues TTL. The internal architecture uses a single-stage CMOS inverter cell with a buffered output, giving consistent drive strength in both directions. Compared with discrete transistor inverters, the integrated 74HCT1G04 delivers matched rise/fall edges, defined propagation delay, and immunity to power-supply variation. The Schmitt-trigger-free design requires clean edges - place a series resistor at the input when driving from long PCB traces to avoid double-triggering. Typical applications include automotive body controllers, sensor-signal inversion in BCM/ECU modules, level translation between 3.3 V microcontrollers and 5 V peripherals, reset-signal conditioning, and clock inversion in portable and industrial devices. The Q-100 qualification also opens infotainment, ADAS sensor pre-processing, and lighting-control modules. Designers should treat the 5-TSSOP land pattern as the layout contract; pin 1 dot-marker is at top-left. Bypass VCC with a 100 nF ceramic placed within 5 mm of the supply pin. The input clamp diodes allow direct connection to voltages above VCC through a current-limiting resistor (typically 10 kΩ).

74LS244N - Octal Buffer/Line Driver 3-State 20-PDIP | TI
The Texas Instruments 74LS244N is an octal buffer and line driver with 3-state outputs in a 20-pin PDIP package, organized as two non-inverting 4-bit elements with independent active-low output-enable controls. It is a Low-power Schottky (LS) TTL device operating from a 4.75 V to 5.25 V supply with TTL-compatible inputs that include PNP inputs to reduce DC loading on upstream drivers. The device sinks up to 24 mA per output in the LOW state and sources up to -15 mA in the HIGH state, providing strong drive for heavily loaded buses. An octal buffer/line driver is a type of bus-interface logic IC used to isolate, boost, and directionally drive parallel data, address, or control signals between a controller and a bus. The 74LS244 is the de-facto industry standard 'bus driver' in the 74LS logic family and is widely second-sourced. It is commonly employed as a memory-address driver, clock driver, or bus-oriented transmitter/receiver, sitting one tier below the system CPU in the digital logic hierarchy and one tier above discrete bus traces. Key features of the 74LS244N include symmetric active-low output-enable (1G, 2G) inputs that allow grouping into two 4-bit banks, 3-state outputs that present a high-impedance state when disabled, input hysteresis for improved noise margin, and ESD protection that exceeds typical 74LS ratings. The 'N' suffix denotes the through-hole 20-pin PDIP package, while 'M' would denote SOIC and 'NS' denotes SOP. Architecturally, the 74LS244N uses bipolar Low-power Schottky technology with a Schottky-clamped transistor design that delivers low propagation delay (typically around 10-12 ns) at modest power consumption compared to standard 74-series TTL. The two independent enable lines let designers disable half the bus while the other half remains active, which is useful in mixed-voltage or partial-power-down designs. Typical applications include memory-address bus buffering in 8-bit microcomputer and retrocomputing designs (Z80, 6502, 8080), clock-driver fan-out, peripheral-interface buffering, and bus isolation in educational or industrial PLC systems. It is also used to drive long PCB traces or backplane lines where the source drive of a typical microcontroller output would be insufficient. When designing with this part, ensure that both 1G and 2G are tied LOW during normal operation to enable outputs, and that the high-impedance state is used to isolate two devices sharing a bus. Decoupling VCC with a 0.1 uF ceramic capacitor placed close to the supply pin is recommended to suppress switching transients. This page synthesizes distributor pricing, same-package drop-in alternatives, and practical design notes that are not found in the bare manufacturer datasheet, helping engineers compare second-source options and design a robust bus-buffer stage.
74LV1T34GV-Q100H - 1.65-5.5V Level Translating Buffer SC-74A | Nexperia
The Nexperia 74LV1T34GV-Q100H is a single, non-inverting, level-translating CMOS buffer in a 5-pin SC-74A (SOT-753) surface-mount package. It supports an input range that allows 1.8 V CMOS logic signals to drive a 3.3 V rail (level-up translation), while 5 V-tolerant inputs enable 3.3 V-to-2.5 V level-down translation at VCC = 2.5 V. The output level references the supply voltage and supports 1.8 V, 2.5 V, 3.3 V, and 5 V rails from a single device. A level-translating buffer is a logic buffer that accepts input voltages from a wide range of logic families and re-references its output to the local supply. This category sits inside the broader class of voltage level shifters, which in turn belong to logic ICs and interface ICs used in mixed-voltage digital systems. By collapsing 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V interfaces onto a single part, these devices reduce BOM count in multi-rail SoC designs. Key features include CMOS low-power operation, push-pull drive, ±8 mA output drive capability, and a wide VCC operating range of 1.6 V to 5.5 V. Inputs accept logic levels above VCC up to 5.5 V regardless of the supply, and the device is qualified to AEC-Q100 Grade 1 for automotive applications, supporting operation from -40 C to +125 C. Internally, the 74LV1T34GV-Q100H uses a single NMOS/PMOS stage with low-threshold input transistors that recognise a logic HIGH far below the supply rail. The output stage is a symmetric push-pull CMOS driver that swings rail-to-rail, giving balanced edge rates for both rising and falling transitions and avoiding the DC current path that open-drain translators require. Typical applications include GPIO voltage translation between a 1.8 V application processor and 3.3 V peripherals, I2C/SPI/UART level shifting between microcontrollers and 5 V sensors, signal conditioning for SD cards and SIM interfaces, automotive body controllers and infotainment links, and any point-to-point signal where board rework to a multi-channel translator would be unnecessary. When designing with this part, confirm that the input HIGH threshold stays below the driver's VOH at the chosen VCC and keep the trace under a few centimetres because this single-channel buffer does not include series damping. Add a 100 nF decoupling cap next to VCC and avoid pulling the input above 5.5 V even though it is 5 V-tolerant. This page synthesises distributor stock, drop-in same-package alternatives, and practical design notes not found in the Nexperia datasheet, providing a single-engineer reference for level-shifting buffer selection.
74LVC1G00GW - Single 2-Input NAND Gate, 1.65V-5.5V | Nexperia
The Nexperia 74LVC1G00GW is a single 2-input NAND gate fabricated with sub-micron Si-gate CMOS technology, providing high-performance low-power low-voltage logic in a 5-pin TSSOP (SOT-353 / UMT5) surface-mount package. The part operates from a wide supply voltage range of 1.65 V to 5.5 V, delivers ±24 mA output drive at VCC = 3.0 V, and supports a propagation delay of approximately 10.5 ns at nominal conditions, making it well suited to modern mixed-voltage systems where 3.3 V and 5 V domains coexist on the same board. An LVC (Low-Voltage CMOS) gate is a sub-family of advanced CMOS logic optimized for operation below 5 V while remaining tolerant of 5 V input signals. Within the broader logic hierarchy, the 74LVC1G00 sits inside the single-gate 74LVC1G family, which in turn belongs to Nexperia's 74LVC logic IC portfolio for power-efficient portable, industrial, and computing designs. Unlike legacy HC/T families, LVC combines low static power consumption with high noise immunity and JEDEC-compliant interface thresholds. Key features include Schmitt-trigger inputs that tolerate slow or noisy edges, ±24 mA balanced output drive (VCC = 3.0 V) for direct LED or bus loading, latch-up performance exceeding 250 mA per JEDEC JESD78, CMOS low static power consumption, and IOFF partial-power-down support that prevents back-feed currents when the device is unpowered but signal lines remain live. Inputs accept 3.3 V or 5 V logic levels, allowing the part to act as a down-translator in mixed-voltage systems without external level-shifters. Typical applications span portable and battery-powered electronics, mobile phones and wearables, level shifting between 5 V microcontrollers and 3.3 V peripherals, general-purpose glue logic on FPGA and ASIC boards, and interface buffering in industrial control and white-goods modules. The compact 5-pin TSSOP footprint enables placement near connectors and signal sources for short, clean traces. When designing with this device, always observe the absolute-maximum VCC of 6.5 V and derate output current above VCC = 4.5 V. Place a 0.1 µF decoupling capacitor as close as possible to VCC pin 5, and unused inputs must be tied to VCC or GND to prevent floating-input quiescent current. The TSSOP-5 footprint is mechanically compatible with Nexperia's entire 74LVC1Gxx single-gate family, simplifying BOM consolidation. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on the manufacturer product page alone, giving the engineer a single reference for sourcing and second-sourcing decisions.
74LVC1G123DC - Single Retriggerable Monostable Multivibrator | Nexperia
The Nexperia 74LVC1G123DC is a single retriggerable monostable multivibrator with Schmitt-trigger inputs housed in an 8-pin VSSOP (DC) package, operating from 1.65 V to 5.5 V VCC with a typical propagation delay of 5.3 ns at 5 V VCC and CMOS-level totem-pole output drive. The device programs its output pulse width via an external resistor (REXT) and capacitor (CEXT), and supports retriggering through either the gated active-LOW A input or the active-HIGH B input. An integrated Ioff circuitry disables the outputs during partial power-down, preventing damaging backflow current in mixed-voltage buses. What is a monostable multivibrator? A monostable multivibrator (commonly called a one-shot) is a sequential logic element with one stable state and one temporary state. Upon receiving a valid trigger edge, the circuit switches to the temporary state for a programmed interval, then returns to the stable state. The 74LVC1G123 belongs to the LVC (Low-Voltage CMOS) logic family within the broader CMOS logic IC hierarchy, occupying the specialty-logic sub-category alongside multivibrators, Schmitt triggers, and buffers. Key features include three pulse-width control methods: external R-C programming, retriggering via the gated active-LOW A or active-HIGH B input, and direct reset via the CLR input. Schmitt-trigger action on both trigger inputs (A and B) makes the device highly immune to slow or noisy edges - typical hysteresis of approximately 0.8 V at 3.3 V VCC rejects input noise of several hundred millivolts. The wide 1.65 V to 5.5 V supply range enables direct interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without external level shifters. The architecture combines an edge-triggered control gate, a precision pulse-width timing core, and a totem-pole CMOS output stage capable of sourcing/sinking up to 32 mA at 3.3 V. Ioff partial-power-down support means the device can be inserted into live buses safely when VCC is removed - a critical feature for hot-swap or multi-rail designs. The Schmitt hysteresis on both trigger inputs delivers reliable operation in electrically noisy industrial environments where standard CMOS gates would double-trigger. Typical applications include pulse generation in industrial control, watchdog timer circuits, debouncing mechanical switches and rotary encoders, missing-pulse detection in motor-control feedback loops, and reset pulse shaping in microcontroller-based systems. The 5 V tolerance on outputs (when VCC = 3.3 V) also makes it useful for legacy 5 V peripheral interfacing in mixed-voltage systems. When designing with the 74LVC1G123DC, select the external REXT and CEXT using the datasheet pulse-width formula tw = REXT × CEXT × ln(2) ≈ 0.69 × REXT × CEXT and verify timing across process, voltage, and temperature corners. Place CEXT as close as possible to the device pins to minimize parasitic capacitance that would otherwise skew the timing accuracy.

74LVC1G27GW - Single 3-Input NOR Gate, 1.65-5.5V | Nexperia
The Nexperia 74LVC1G27GW is a single 3-input NOR gate IC in the 74LVC (Low-Voltage CMOS) logic family, packaged in a 6-pin TSSOP (SOT-363/SC-88). It provides one 3-input NOR function and accepts a wide supply voltage range from 1.65 V to 5.5 V, supporting both 3.3 V and 5 V mixed-voltage applications. Inputs can be driven from either 3.3 V or 5 V devices, allowing its use as a translator between logic domains without external level shifters. A logic gate is a fundamental building block of digital electronics that performs a Boolean operation on one or more binary inputs to produce a single binary output. The 3-input NOR gate outputs logic HIGH only when ALL three inputs are LOW; if any input is HIGH, the output is LOW. As part of the NOR gate hierarchy, this device is a member of the broader logic IC family, which also includes AND, OR, NAND, XOR, and inverter gates. NOR gates are functionally complete and can be combined to construct any other logic function, making them especially valuable in glue logic and minimal-component designs. Key features of the 74LVC1G27GW include 24 mA output drive capability at VCC = 3.0 V, CMOS low power consumption, and Schmitt-trigger action at all inputs for tolerance to slow rise/fall times. ESD protection meets HBM JESD22-A114F (>2000 V), MM JESD22-A115-A (>200 V), and CDM JESD22-C101-C (>1000 V). It complies with JEDEC standards JESD8-7, JESD8-5, and JESD8B/JESD36, and supports IOFF partial power-down operation to prevent backflow current when one side of the device is powered down. Internally, the 74LVC1G27GW uses CMOS technology with sub-micron geometries to deliver rail-to-rail output swings at low quiescent current. The Schmitt-trigger input hysteresis improves noise immunity in noisy environments and makes the device tolerant of slowly changing input signals. With 50 ns typical propagation delay at 3.3 V and a tiny 6-pin footprint, the device is optimized for high-density PCB designs where board area and signal integrity are critical. Typical applications include voltage level translation between 3.3 V and 5 V buses, glue logic in microcontroller interfaces, signal inversion and combination in industrial controls, and handheld or battery-powered portable equipment requiring low-power operation. The wide supply range enables direct connection to single-cell Li-ion batteries (3.0 V to 4.2 V) or to regulated 1.8 V rails in modern SoCs. When designing with this device, ensure that VCC is properly decoupled with a 100 nF ceramic capacitor placed within 5 mm of the VCC pin. Unused inputs should be tied to VCC or GND through a defined logic level; never leave inputs floating because the Schmitt-trigger hysteresis can cause oscillation. For mixed-voltage applications, confirm that input high-level voltage (VIH) and low-level voltage (VIL) thresholds of the driving device are compatible with the 74LVC family at your chosen VCC.

74LVC1G27GW-Q100H - Single 3-Input NOR Gate, Automotive | Nexperia
The Nexperia 74LVC1G27GW-Q100H is a single 3-input NOR gate fabricated in CMOS silicon-gate technology and qualified to the AEC-Q100 automotive standard. It operates from a 1.65 V to 5.5 V supply, supports 32 mA output drive (sink and source), and delivers a typical propagation delay of 4.5 ns at 5 V with 50 pF load, all housed in a 6-pin SOT363 (SC-88) package. The Q100 suffix and H designation confirm full automotive-grade qualification with PPAP support. A NOR gate is a fundamental digital logic gate that produces a logic-high output only when ALL of its inputs are logic-low; if any input is high, the output is forced low. The 3-input variant integrates three parallel OR inputs followed by inversion, useful for compact combinational logic, multi-input fault detection, and qualification functions. NOR gates sit within the broader logic family hierarchy as: NOR gate -> OR-derived logic -> combinational logic -> CMOS logic -> integrated circuit. Key features include wide 1.65 V to 5.5 V supply operation, 5 V tolerant inputs that allow direct interfacing with 3.3 V or 5 V devices, Schmitt-trigger input action for noise immunity with slow edges, and I_OFF circuitry that enables partial power-down by preventing damaging backflow current when the device is unpowered. Typical quiescent current is 4 uA, and the device supports output voltages from 0.95 V to VCC - 0.5 V (3.4 V at 5 V supply). The 74LVC1G27GW-Q100H uses Nexperia's LVC (Low-Voltage CMOS) technology, optimized for low power and high speed at low voltages. The Schmitt-trigger inputs provide hysteresis that prevents oscillation on slow input transitions, which is essential in industrial and automotive environments with long PCB traces. The I_OFF feature makes the part safe for hot-insert and bus-isolated applications where partial sections are powered down to save energy. Typical applications include automotive body and chassis electronics, industrial sensor signal conditioning, level translation between 3.3 V and 5 V logic domains, handheld battery-powered devices, and embedded computing boards requiring a single compact NOR gate rather than a multi-channel package. The -40 C to +125 C operating range supports under-hood and outdoor deployments. When designing with this part, observe 5 V tolerant input thresholds and derate output drive at low VCC: at 1.8 V supply the 32 mA rating drops significantly. Always check the I_OFF specification if the device sits on a live bus while locally unpowered. The SC-88 (SOT363) footprint is the same as the SC-70 family and is footprint-compatible with industry-standard 6-pin micro-logic packages.

74LVC1GU04GW,125 - Single Unbuffered Inverter | Nexperia | 5-TSSOP
The Nexperia 74LVC1GU04GW,125 is a single unbuffered inverter IC housed in a 5-pin TSSOP (SOT-353/UMT5) package, built on a Si-gate CMOS process that delivers superior performance over most advanced CMOS-compatible TTL families. The device operates across a wide 1.65 V to 5.5 V supply range and accepts input drive levels from either 3.3 V or 5 V logic, making it drop-in compatible with mixed-voltage system designs. As an unbuffered (raw inverter) topology, it provides the shortest possible propagation delay in its class while maintaining low static power consumption. An unbuffered inverter is a single-input CMOS logic function that inverts the input logic level at the output without an internal Schmitt-trigger or amplification stage. This places the unbuffered inverter in the digital-logic IC family hierarchy: inverter -> gate -> combinational logic -> logic IC -> integrated circuit -> semiconductor. Unbuffered inverters are preferred over buffered (standard) inverters in oscillator circuits, linear amplifiers, and analog signal paths because the absence of an internal gain stage preserves signal linearity and minimizes additive phase shift. The 74LVC1GU04GW,125 features a typical quiescent current of 100 µA, ±24 mA output drive capability at 3.3 V, and propagation delay of 1.7 ns typical at 3.3 V VCC with 15 pF load. The wide operating voltage window, schmitt-tolerant inputs, and 5-pin TSSOP footprint make it ideal for portable, IoT, and space-constrained PCB layouts. Nexperia's LVC family is also characterized by low-power operation, making it suitable for battery-powered applications where quiescent current directly affects runtime. The device architecture uses a single CMOS inverter cell whose output transitions follow the input directly without hysteresis. This raw-inverter topology is essential when the inverter is used as a linear amplifier or in crystal-oscillator feedback loops where the buffered variant's gain stage would distort the waveform. The 5-pin SOT-353 package provides a compact 2.0 mm x 1.25 mm x 1.1 mm outline. Typical applications include crystal oscillator modules, sine-wave to logic-level converters, level translation in mixed 3.3 V / 5 V systems, and general-purpose logic inversion in portable and IoT devices. The device is also commonly used as a small-signal amplifier in RF detector circuits and as a delay element in digital timing chains. When designing with this part, note that the input has no Schmitt-trigger hysteresis; therefore, slow or noisy edges may produce multiple output transitions. Place a small series resistor at the input (typically 100 ohm to 1 kohm) when driving from long PCB traces to control edge rate. The 5-TSSOP package has a thermal resistance of approximately 250 C/W, so output current must be limited well below 24 mA continuous in high-ambient-temperature environments.
