Nexperia USA Inc. 74AHCU04PW,118

Overview

74AHCU04PW,118 from Nexperia is a high-speed Si-gate CMOS hex unbuffered inverter with six independent single-stage inverters, pin-compatible with LSTTL, operating from -40 °C to +125 °C, supporting VCC = 2.0–5.5 V, and delivering tpd ≤ 7.0 ns (VCC = 5.0 V, CL = 50 pF) for digital logic level translation and oscillator biasing.

For engineers reviewing the 74AHCU04PW,118 datasheet, 74AHCU04PW,118 pinout, 74AHCU04PW,118 application, or 74AHCU04PW,118 equivalent, this device is selected for low-power, rail-to-rail input-tolerant logic inversion in industrial control timing, crystal oscillator buffering, and mixed-voltage interface circuits where balanced propagation delay and ESD-hardened inputs are required.

Technical Context

The 74AHCU04PW,118 implements six identical unbuffered CMOS inverter stages-each consisting of a single P-channel and N-channel MOSFET pair-enabling direct use as linear amplifiers or crystal oscillator gain elements when biased via external resistors. Its input structure accepts voltages up to 7.0 V regardless of VCC, enabling level-shifting across voltage domains.

It complies with JEDEC Std 7A and supports operation across the full industrial temperature range (-40 °C to +125 °C), with static VIH/VIL thresholds defined at 4.4 V and 1.1 V (VCC = 5.5 V), and dynamic performance validated under 15 pF and 50 pF loads at both 3.3 V and 5.0 V supply conditions.

FAQ

Can the 74AHCU04PW,118 be used as a linear amplifier?

Yes - its unbuffered CMOS structure allows DC biasing into the linear region using resistor feedback (Fig. 11). With R1 ≥ 3 kΩ and R2 ≤ 1 MΩ, it delivers ~5 MHz unity-gain bandwidth and open-loop gain of ~12, enabling low-noise signal conditioning without op-amps.

What is the maximum capacitive load the 74AHCU04PW,118 can drive reliably?

It is characterized up to 50 pF (Table 7), with tpd ≤ 9.0 ns at +125 °C. Driving >50 pF risks increased propagation delay, reduced noise margin, and potential ringing; for heavier loads, add series termination or buffer stages.

Does the exposed pad on the TSSOP14 package require soldering or grounding?

No - the exposed pad (terminal 1 index area) has no electrical function. Per datasheet Section 5.1, it may remain unsoldered or be floated; if soldered, it must be left electrically floating or tied to GND, with no mechanical or electrical requirement to do so.

How does the 74AHCU04PW,118 differ from standard 74HC04 devices?

Unlike buffered 74HC04, the "U" in AHCU denotes unbuffered architecture - enabling crystal oscillator use and linear amplification. It also features enhanced input overvoltage tolerance (up to +7.0 V), tighter propagation delay matching, and guaranteed operation to +125 °C in TSSOP14.
