Nexperia USA Inc. 74HC1GU04GV-Q100,1

Overview

74HC1GU04GV-Q100 from Nexperia is a single unbuffered CMOS inverter qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0–6.0 V, propagation delay as low as 6 ns at VCC = 6.0 V/CL = 50 pF, and symmetrical output impedance enabling clean signal inversion in timing-critical control paths.

For engineers reviewing the 74HC1GU04GV-Q100 datasheet, 74HC1GU04GV-Q100 pinout, 74HC1GU04GV-Q100 application, or 74HC1GU04GV-Q100 equivalent, this device serves as a compact, high-noise-immunity logic inverter in automotive body control modules, sensor interface conditioning, and crystal oscillator biasing circuits where space-constrained SC-74A packaging and rail-to-rail input tolerance are essential.

Technical Context

This unbuffered inverter implements a single-stage CMOS inverting gate with clamp diodes on the input (pin 2), allowing safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Its internal structure lacks buffering stages, resulting in lower propagation delay but higher sensitivity to capacitive loading compared to buffered variants.

It supports dual temperature ranges (−40 °C to +125 °C), complies with JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), and delivers balanced tPLH/tPHL delays - critical for clock shaping and waveform inversion in feedback loops such as Pierce oscillators.

FAQ

What is the maximum allowable input voltage when VCC = 5.0 V?

The absolute maximum input voltage is VCC + 0.5 V = 5.5 V, provided the input current remains within ±20 mA per the clamping current rating. This is enabled by internal clamp diodes - always use a series current-limiting resistor (e.g., 10 kΩ for 12 V inputs) to stay within IIK limits and avoid damage.

Can 74HC1GU04GV-Q100 drive a 100 pF load reliably at 10 MHz?

No - at CL = 100 pF, propagation delay increases significantly beyond datasheet specs (tested at 50 pF). Measured tpd may exceed 30 ns, and output rise/fall times degrade, risking timing violations. For 100 pF loads, consider buffered inverters like 74HC1G14 or add a fanout buffer stage.

Is pin 1 (n.c.) electrically isolated or internally tied to substrate?

Pin 1 is truly not connected - no internal bond wire or silicon connection exists. It is electrically and functionally isolated. Do not solder it to PCB traces or planes; leaving it floating is safe and recommended per Nexperia's package design.

How does the device behave when VCC is ramped slowly during power-up?

Due to unbuffered design and lack of power-on reset circuitry, the output may oscillate or enter metastability if input A is near VCC/2 during VCC ramp. To prevent glitching, hold A at a defined logic level (e.g., pull-down to GND) until VCC stabilizes above 2.0 V, as specified in recommended operating conditions.
