Nexperia USA Inc. 74AHC3GU04DP-Q100H

Overview

74AHC3GU04DP-Q100 from Nexperia is a triple unbuffered inverter IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0–5.5 V, overvoltage-tolerant inputs up to 5.5 V, and symmetrical output impedance. It delivers balanced propagation delays (≤10.0 ns at VCC = 5.5 V, CL = 50 pF) and supports mixed-voltage logic translation in body control modules and infotainment power sequencing.

For engineers reviewing the 74AHC3GU04DP-Q100 datasheet, 74AHC3GU04DP-Q100 pinout, 74AHC3GU04DP-Q100 application, or 74AHC3GU04DP-Q100 equivalent, key selection criteria include automotive temperature compliance, unbuffered inverter gain characteristics for oscillator design, input overvoltage tolerance in 3.3 V/5 V interface domains, and TSSOP8 package suitability for space-constrained PCB layouts.

Technical Context

This device implements three independent CMOS unbuffered inverters in a single monolithic die. Each gate features high noise immunity, rail-to-rail output swing, and input thresholds referenced to VCC - enabling reliable operation across 2.0 V to 5.5 V supply rails without level-shifting circuitry.

The unbuffered architecture provides inherent linear-region gain suitable for crystal oscillator configurations and analog amplifier applications, as confirmed by typical unity-gain bandwidth of 5 MHz and open-loop gain of 20 at VCC = 3 V. Input clamping current is limited to ±20 mA, supporting robust ESD resilience per HBM (>2000 V) and CDM (>1000 V) standards.

FAQ

Is the 74AHC3GU04DP-Q100 pin-compatible with the 74AHC3GU04DC-Q100?

Yes - both share identical pin functions (1A, 2A, 3A, GND, 1Y, 2Y, 3Y, VCC) and logic behavior. The only difference is package: DP uses TSSOP8 (SOT505-2, 3 mm body width), while DC uses VSSOP8 (SOT765-1, 2.3 mm body width). PCB layout must match respective land patterns and thermal pad requirements.

Can this device be used as a linear amplifier, and what are the key design constraints?

Yes - its unbuffered structure enables linear-mode operation per Figure 9. Key constraints: bias resistors R1 ≥ 3 kΩ and R2 ≤ 1 MΩ; load impedance ZL > 10 kΩ; maximum peak-to-peak output is VCC − 1.5 V centered at 0.5 × VCC; unity-gain bandwidth is ~5 MHz at VCC = 3 V.

What is the maximum capacitive load this inverter can drive while maintaining specified propagation delay?

At VCC = 5.0 V, the datasheet guarantees tpd ≤ 7.0 ns for CL = 50 pF. Driving >50 pF increases delay nonlinearly - e.g., CL = 100 pF yields ~10.5 ns tpd. For stable timing, keep total load (including trace capacitance and probe effects) ≤50 pF unless derating delay specs.

Does the overvoltage-tolerant input specification apply when VCC is powered down?

Yes - inputs tolerate up to 5.5 V even with VCC = 0 V, as confirmed by VI absolute maximum rating (-0.5 V to +7.0 V) and IOK clamping current limit (±20 mA). This enables hot-plug compatibility and safe interfacing with live backplanes during partial power-down sequences.
