Nexperia USA Inc. 74LVC1G332GW,125

Overview

74LVC1G332GW,125 from Nexperia is a single 3-input OR gate logic IC in TSSOP6 (SOT363-2) package, operating from 1.65 V to 5.5 V supply, featuring Schmitt-trigger inputs for noise immunity, ±24 mA output drive at 3.0 V, IOFF partial power-down protection, and guaranteed operation from –40 °C to +125 °C. It enables level translation between 3.3 V and 5 V domains in compact interface circuits.

For engineers reviewing the 74LVC1G332GW,125 datasheet, 74LVC1G332GW,125 pinout, 74LVC1G332GW,125 application, or 74LVC1G332GW,125 equivalent, key selection considerations include input voltage tolerance up to 5.5 V, propagation delay as low as 1.0 ns at 5.5 V, IOFF-enabled system-level power sequencing, and compatibility with mixed-voltage board-level signal routing.

Technical Context

This device implements a standard positive-logic 3-input OR function (Y = A + B + C) with Schmitt-trigger inputs that provide hysteresis (typ. 0.3 V at VCC = 3.3 V), enabling robust operation with slow-rising or noisy signals. The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down sequences.

It supports dual-supply interoperability: inputs tolerate 5.5 V regardless of VCC (1.65–5.5 V), allowing direct connection to 5 V drivers while powered from 3.3 V or lower rails. Output VOH/VOL specifications are guaranteed across the full voltage and temperature range, with dynamic performance characterized up to 5.5 V supply.

FAQ

Can 74LVC1G332GW,125 operate with VCC = 1.65 V while accepting 5 V inputs?

Yes. Inputs are overvoltage tolerant to 5.5 V regardless of VCC value. At VCC = 1.65 V, VIH is guaranteed ≥0.65 × VCC (≥1.07 V), and VIL ≤0.35 × VCC (≤0.58 V), enabling reliable detection of 5 V logic highs via internal clamping. No external resistors or level shifters are needed.

What is the maximum capacitive load the output can drive while maintaining specified tpd?

The datasheet specifies tpd test conditions with CL = 30 pF (for VCC ≤2.7 V) or 50 pF (for VCC ≥3.0 V). Driving >50 pF increases propagation delay nonlinearly and may degrade edge rates; for loads >50 pF, add a series resistor (10–33 Ω) near the output to damp ringing without significantly affecting delay.

Does IOFF functionality require external biasing or control signals?

No. IOFF is fully automatic and requires no external configuration. When VCC drops to 0 V, the internal circuitry disables both PMOS and NMOS output transistors, presenting a high-impedance state with ≤2 μA leakage-no pull-up/down resistors or enable pins are involved.

How does Schmitt-trigger input behavior affect signal integrity with slow-rising sensor outputs?

Schmitt-trigger inputs provide ~0.3 V hysteresis at VCC = 3.3 V, meaning the rising threshold is ~1.9 V and falling threshold is ~1.6 V. This prevents multiple transitions on slowly rising signals (e.g., thermistor-based voltage ramps), ensuring clean, single-event detection without external debouncing circuitry.
