Nexperia USA Inc. 74AHC1GU04GW,125

Overview

74AHC1GU04GW,125 from Nexperia is a single unbuffered CMOS inverter IC with overvoltage-tolerant inputs (up to 5.5 V), operating across 2.0–5.5 V supply range, specified from −40 °C to +125 °C, and housed in a 5-lead TSSOP5 (SOT353-1) package. It delivers symmetrical output impedance, high noise immunity, and supports voltage translation in mixed-voltage digital interfaces.

For engineers reviewing the 74AHC1GU04GW,125 datasheet, 74AHC1GU04GW,125 pinout, 74AHC1GU04GW,125 application, or 74AHC1GU04GW,125 equivalent, key selection criteria include input overvoltage tolerance, propagation delay under 7.1 ns (VCC = 3.3 V, CL = 15 pF), low ICC (≤40 μA at VCC = 5.5 V), −40 °C to +125 °C operation, and TSSOP5 thermal performance with 3.3 mW/K derating above 74 °C.

Technical Context

This device implements a single-stage unbuffered inverter topology with rail-to-rail CMOS output drive, enabling direct use as a level translator between 1.8 V/3.3 V and 5 V domains without external biasing. Its overvoltage-tolerant inputs accept up to 5.5 V independent of VCC, supporting bidirectional voltage translation when VCC is set to the lower domain.

The logic function is strictly inverting (L→H, H→L), with no internal hysteresis or Schmitt-trigger behavior. Propagation delay is characterized across temperature and load (CL = 15 pF / 50 pF), and dynamic power dissipation is governed by CPD = 14 pF and supply voltage squared scaling per the formula PD = CPD × VCC² × fi.

FAQ

Can 74AHC1GU04GW,125 be used as a crystal oscillator buffer?

Yes. The datasheet explicitly validates its use in Pierce oscillator configurations (Fig. 12), with typical ICC = 2 mA at VCC = 3 V and 1 MHz. Its unbuffered architecture provides appropriate phase shift and gain margin for 32.768 kHz and up to ~600 kHz crystals when biased with R1/R2 per Table 9, and it sustains oscillation across the full −40 °C to +125 °C range.

What is the maximum capacitive load this inverter can drive reliably?

The device is characterized up to CL = 50 pF (Table 8), with tpd = 13.5 ns max at −40 °C to +125 °C and VCC = 4.5 V. Driving >50 pF risks excessive delay, reduced noise margin, and potential waveform distortion; for heavier loads, add a buffer stage or select a higher-drive variant like 74AHC1G14.

Is pin 1 of the TSSOP5 package marked, and how is it oriented?

Yes. Per Table 2 and Fig. 13, pin 1 is indicated by a dot or notch located on the lower-left corner of the device body, directly below the marking code "AD". The package follows standard TSSOP orientation: leads numbered counter-clockwise from pin 1, with pin 1 at bottom-left, pin 5 at top-right.

Does this part support 1.8 V logic levels when VCC = 1.8 V?

No. The absolute minimum VCC is 2.0 V per Table 6. At 1.8 V, the device falls outside recommended operating conditions-VIH would be undefined, VOH/VOL margins collapse, and functionality is not guaranteed. For 1.8 V systems, consider 74LVC1G04 or 74AUP1G04 instead.
