NXP Semiconductors 74HC04PW/AUJ

Overview

74HC04PW/AUJ from NXP USA Inc. is a hex inverter designed for general-purpose CMOS logic, signal inversion, waveform polarity conversion, enable-signal conditioning, oscillator support circuits, and embedded digital control applications. The device integrates six independent inverter gates in a compact 14-lead TSSOP package, allowing multiple logic inversion functions to be implemented with one standard logic IC.

As part of the 74HC04 high-speed CMOS logic family, 74HC04PW/AUJ combines a 2.0V to 6.0V supply range, CMOS input levels, low power dissipation, high noise immunity, input clamp diodes, and standard hex inverter functionality for flexible board-level logic integration. For engineers reviewing the 74HC04PW/AUJ datasheet, 74HC04PW/AUJ pinout, 74HC04PW/AUJ application, or 74HC04PW/AUJ equivalent, this device is widely used in logic inversion, signal buffering, address and enable polarity conversion, oscillator circuits, timing networks, embedded controllers, industrial boards, and general-purpose CMOS logic designs.

Technical Context

In digital logic systems, 74HC04PW/AUJ provides six independent inverter gates. Each channel outputs the opposite logic state of its corresponding input: a LOW input produces a HIGH output, while a HIGH input produces a LOW output. This makes the device useful for signal polarity conversion, logic-level qualification, simple waveform shaping, and control-signal inversion.

The HC version uses CMOS input thresholds and operates across a 2.0V to 6.0V supply range, making it suitable for CMOS-level 3.3V and 5V systems. Compared with HCT versions, the HC device is not intended for TTL-level input thresholds; designers should verify that the driving circuit provides valid CMOS HIGH and LOW levels for the selected VCC.

The inputs include clamp diodes, allowing current-limited interfacing to voltages above VCC. This can simplify certain mixed-voltage or overvoltage-tolerant interface arrangements when external resistors limit input current, but absolute maximum ratings and clamp-current limits must still be followed during circuit design.

Key Specifications

Pinout & Package

The 74HC04PW/AUJ pinout uses a 14-lead TSSOP package with six independent inverter channels. Inputs 1A to 6A are placed on pins 1, 3, 5, 9, 11, and 13, while outputs 1Y to 6Y are placed on pins 2, 4, 6, 8, 10, and 12. Pin 7 is GND and pin 14 is VCC.

For PCB implementation, VCC should be bypassed close to the package, unused inputs should be tied to VCC or GND, and outputs should remain within the recommended load limits. Because inverters are often used for timing and polarity conversion, clean input transitions and valid CMOS threshold margins should be maintained.

Applications

Equivalent & Alternatives

When evaluating 74HC04PW/AUJ equivalent devices, engineers should compare logic family, input threshold type, supply-voltage range, package footprint, propagation delay, output drive, oscillator suitability, operating temperature, ESD rating, and pin-to-pin compatibility.

Compared with 74HCT04PW, 74HC04PW/AUJ is optimized for CMOS-input logic systems and wider 2.0V to 6.0V operation rather than TTL-level 5V input compatibility. 74HC04PW/AUJ vs 74HC04D selection depends mainly on package footprint, PCB area, assembly preference, and existing SO14 or TSSOP14 layout qualification.

Quality

74HC04PW/AUJ should be sourced as original NXP or Nexperia-family components through traceable and controlled supply channels. Quality verification procedures may include package inspection, top-mark validation, solderability testing, pin continuity checks, input threshold verification, functional inverter truth-table testing, output-level measurement, and incoming inspection according to standard logic production requirements.

Because the device is frequently used in control, reset, enable, and timing logic, system reliability depends on valid CMOS input levels, clean supply decoupling, stable input timing, tied unused inputs, correct output loading, and verified logic polarity. Traceable sourcing supports manufacturing quality and reduces counterfeit supply-chain risk for standard logic production programs.
