Nexperia USA Inc. 74LVC1GU04GV-Q100H

Overview

74LVC1GU04GV-Q100 from Nexperia is a single unbuffered inverter qualified to AEC-Q100 Grade 1 for automotive use, operating from −40 °C to +125 °C with supply voltage range 1.65 V to 5.5 V, overvoltage-tolerant inputs up to 5.5 V, and ±24 mA output drive at V_CC = 3.0 V. It enables level-shifting between 3.3 V and 5 V logic domains in engine control units and body electronics.

For engineers reviewing the 74LVC1GU04GV-Q100 datasheet, 74LVC1GU04GV-Q100 pinout, 74LVC1GU04GV-Q100 application, or 74LVC1GU04GV-Q100 equivalent, key selection criteria include automotive temperature compliance, unbuffered inverter gain characteristics for oscillator design, input overvoltage tolerance, and SC-74A (SOT753) package compatibility with high-density PCB layouts.

Technical Context

This device implements a CMOS unbuffered inverter stage with no internal buffering-enabling direct use as a linear amplifier or crystal oscillator gain element. Its input threshold is adaptive: V_IL ≤ 0.2 × V_CC and V_IH ≥ 0.8 × V_CC across −40 °C to +125 °C, supporting robust noise immunity in noisy automotive environments.

Propagation delay ranges from 0.5 ns (V_CC = 4.5–5.5 V) to 6.5 ns (V_CC = 1.65–1.95 V) under full temperature range, with power dissipation capacitance of 14.9 pF at V_CC = 3.3 V. Input clamping current rating of ±50 mA and latch-up immunity >250 mA ensure resilience against transient stress.

FAQ

Can 74LVC1GU04GV-Q100 be used as a linear amplifier?

Yes. The unbuffered inverter architecture allows linear-mode operation when DC-biased via external resistors (e.g., R1 ≥ 3 kΩ, R2 ≤ 1 MΩ). Typical loop gain is 20 with unity-gain bandwidth ~5 MHz, enabling use in crystal oscillators and low-noise analog signal conditioning within automotive sensors.

What is the significance of the "n.c." pin in the SC-74A package?

Pin 1 is explicitly designated "not connected" per datasheet Table 3 and has no internal bond wire or silicon connection. It must remain unconnected-neither tied to GND nor V_CC. Routing traces to this pin may introduce parasitic coupling; best practice is to omit pad connection or place keep-out zone.

How does the 74LVC1GU04GV-Q100 handle 5 V inputs while powered from 3.3 V?

Its inputs are overvoltage tolerant up to 5.5 V regardless of V_CC level. This is achieved via integrated clamp diodes to V_CC and GND, rated for ±50 mA clamping current. No external protection is needed when interfacing 5 V legacy peripherals to 3.3 V domains.

Is thermal derating required for continuous operation at +125 °C ambient?

Yes. For the SOT753 (SC-74A) package, total power dissipation derates linearly at 3.8 mW/K above +85 °C. At +125 °C, maximum allowable P_tot drops to ~105 mW (250 mW − 3.8 mW/K × 40 K), requiring careful layout and load current limitation to avoid junction temperature exceedance.
