NXP Semiconductors 74LVC1GU04GV,125

Overview

74LVC1GU04GV,125 from Nexperia is a single unbuffered CMOS inverter optimized for level-shifting and signal conditioning in mixed-voltage systems. It operates across 1.65 V to 5.5 V supply, accepts 5.5 V-tolerant inputs, delivers ±24 mA output drive at 3.0 V, and is rated for -40 °C to +125 °C. It serves as a logic-level translator in USB interface buffers and low-power sensor signal inversion.

For engineers reviewing the 74LVC1GU04GV,125 datasheet, 74LVC1GU04GV,125 pinout, 74LVC1GU04GV,125 application, or 74LVC1GU04GV,125 equivalent, key selection criteria include input overvoltage tolerance (5.5 V), propagation delay (≤5.0 ns at 3.3 V), output drive strength, thermal performance in SC-74A package, and compatibility with 3.3 V/5 V mixed-rail designs.

Technical Context

This device implements a single-stage unbuffered inverter topology-no internal buffering stages-enabling minimal propagation delay and high-speed edge response. Its rail-to-rail input voltage range (0 V to 5.5 V) and supply-independent logic thresholds (VIH = 0.8×VCC, VIL = 0.2×VCC at +125 °C) support robust interfacing between disparate logic families.

The SC-74A (SOT753) package features five terminals: two unused (n.c.), one input (A), one output (Y), one ground (GND), and one supply (VCC). Internal ESD protection meets HBM >2000 V and CDM >1000 V, and latch-up immunity exceeds 250 mA per JEDEC JESD78.

FAQ

Can 74LVC1GU04GV,125 be used with a 5 V input while powered at 1.8 V?

Yes. The device features overvoltage-tolerant inputs rated to 5.5 V independent of VCC. When VCC = 1.8 V, input voltages up to 5.5 V are safely accepted without damage or logic malfunction, enabling direct interfacing with legacy 5 V peripherals in modern low-voltage systems.

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

At VCC = 3.3 V and Tamb = 25 °C, the device maintains ≤5.0 ns propagation delay driving up to 30 pF (per datasheet test conditions). For loads exceeding 30 pF, delay increases linearly; for 50 pF, tPD rises to ≤6.5 ns at +125 °C - still within most digital timing budgets.

Does the SC-74A package support automated optical inspection (AOI)?

Yes. The SOT753 package has exposed copper terminals with defined solder mask openings and coplanar pad geometry compliant with IPC-A-610 Class 2/3. Its 0.65 mm pitch and 1.7 mm body width are fully supported by standard AOI systems for void detection and solder joint quality verification.

Is there a recommended bypass capacitor value and placement for stable operation?

A 100 nF X7R ceramic capacitor is recommended, placed between VCC and GND with trace length ≤2 mm and via-in-pad grounding. This configuration suppresses supply transients induced by 24 mA output switching and maintains VIH/VIL margins under dynamic load conditions.
