Nexperia USA Inc. 74LVC1G32GW,125

Overview

74LVC1G32GW,125 from Nexperia is a single 2-input OR gate logic IC in TSSOP5 (SOT353-1) package, operating from 1.65 V to 5.5 V supply, featuring Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and ±24 mA output drive at 3.0 V - used in level translation between 3.3 V and 5 V subsystems in industrial control I/O interfaces.

For engineers reviewing the 74LVC1G32GW,125 datasheet, 74LVC1G32GW,125 pinout, 74LVC1G32GW,125 application, or 74LVC1G32GW,125 equivalent, key selection factors include its overvoltage-tolerant 5.5 V inputs, -40 °C to +125 °C extended temperature rating, IOFF-enabled hot-swap capability, and propagation delay as low as 1.7 ns at 5.5 V.

Technical Context

This device implements standard positive-logic OR functionality (Y = A + B) with Schmitt-trigger input thresholds enabling robust operation with slow-rising signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

It supports mixed-voltage interfacing: inputs tolerate up to 5.5 V independent of VCC, allowing direct connection to 5 V TTL or CMOS sources while powered from 1.65–3.3 V rails. The TSSOP5 package provides compact surface-mount integration with exposed pad thermal performance.

FAQ

Can 74LVC1G32GW,125 interface a 5 V sensor output directly to a 1.8 V microcontroller GPIO?

Yes - its inputs tolerate up to 5.5 V regardless of VCC, so with VCC = 1.8 V, it safely accepts 5 V logic-high signals and translates them to 1.8 V-compatible outputs. The Schmitt-trigger inputs further suppress noise from long sensor cables, making it ideal for industrial sensor aggregation without external level shifters.

Does 74LVC1G32GW,125 support hot-swap insertion when other system rails remain active?

Yes - the IOFF circuit forces the output into high-impedance when VCC = 0 V, preventing damaging back-current flow from live downstream circuits into the unpowered IC. This enables safe insertion into powered backplanes or modular I/O carriers without disrupting system operation.

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

At VCC = 3.3 V, the datasheet specifies tpd ≤ 4.5 ns (max) with CL = 50 pF. Driving loads beyond 50 pF increases delay nonlinearly; for 100 pF, measured tpd exceeds 7 ns. For timing-critical paths, keep total load (trace + input capacitance) ≤ 40 pF to retain margin below the 4.5 ns limit.

How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?

Its input hysteresis is ≥0.3 × VCC - e.g., ~1.0 V at VCC = 3.3 V - meaning the rising threshold is ~2.0 V and falling threshold is ~1.0 V. This prevents oscillation on slow or noisy edges and rejects transients <1.0 V peak-to-peak, unlike standard CMOS inputs with single ~1.65 V threshold vulnerable to false triggering.
