Nexperia USA Inc. 74AHCT04PW,118

Overview

74AHCT04PW,118 from Nexperia is a hex inverter IC designed for TTL-level logic translation and signal inversion in digital interface circuits. It provides six independent CMOS-compatible inverters with 5 V supply operation, 8 ns typical propagation delay at 5 V/15 pF, and operates across –40 °C to +125 °C. It is used in bus buffering, clock signal conditioning, and level-shifting between legacy TTL and modern CMOS subsystems.

For engineers reviewing the 74AHCT04PW,118 datasheet, 74AHCT04PW,118 pinout, 74AHCT04PW,118 application, or 74AHCT04PW,118 equivalent, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V min), rail-to-rail output swing, low static current (<2 μA at 5.5 V), and TSSOP14 package suitability for high-density PCB layouts.

Technical Context

The 74AHCT04PW,118 implements six independent Schmitt-trigger–free inverting buffers using high-speed Si-gate CMOS technology. Its input structure accepts TTL voltage levels (0.8 V max VIL, 2.0 V min VIH) while driving CMOS loads with VOH ≥ 3.7 V and VOL ≤ 0.55 V at 8 mA sink/source.

It complies with JEDEC Std 7-A and supports mixed-voltage system interfacing via guaranteed noise margins: 0.7 V DC noise immunity at VCC = 5.0 V, and balanced tPLH/tPHL propagation delays (≤8.5 ns max at 5 V/15 pF) enabling deterministic timing in synchronous control paths.

FAQ

What is the maximum clock frequency supported by the 74AHCT04PW,118?

The device does not specify a maximum clock frequency directly, but its 8.5 ns maximum propagation delay at 5 V/15 pF implies reliable operation up to approximately 60 MHz for toggling a single inverter stage. For multi-stage chains, total path delay and setup/hold margins must be verified per design. No internal clock circuitry exists - it is purely combinational logic.

Can the 74AHCT04PW,118 operate at 3.3 V supply?

No. The 74AHCT04 variant is specified only for 4.5 V to 5.5 V operation per JEDEC 7-A and Nexperia's recommended conditions. At 3.3 V, input thresholds become undefined and output drive falls outside specification; use 74AHC04PW instead for 2.0–5.5 V operation with CMOS inputs.

Is the exposed pad on the TSSOP14 package electrically connected?

No. Per Nexperia SOT402-1 documentation, the exposed pad is a thermal enhancement feature with no electrical function. It may remain floating or be connected to GND for improved heat dissipation, but soldering is optional and imposes no electrical requirement.

How does the 74AHCT04PW,118 handle unused inputs?

Unused inputs must be terminated to VCC or GND - floating inputs cause increased ICC, unpredictable output states, and potential oscillation due to intermediate voltage biasing of CMOS gates. Tie unused A-inputs directly to VCC or GND using short traces; do not leave unconnected.
