Nexperia USA Inc. 74LVC1G32GW-Q100H

Overview

74LVC1G32GW-Q100 from Nexperia is a single 2-input OR gate logic IC 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, ±24 mA output drive at VCC = 3.0 V, and IOFF-enabled partial power-down protection.

For engineers reviewing the 74LVC1G32GW-Q100 datasheet, 74LVC1G32GW-Q100 pinout, 74LVC1G32GW-Q100 application, or 74LVC1G32GW-Q100 equivalent, this device serves as a level-translating OR gate in mixed-voltage domains (3.3 V/5 V), features Schmitt-trigger inputs for noise immunity, and supports automotive infotainment, body control, and ADAS subsystems requiring robust static/dynamic performance and I/O isolation during power sequencing.

Technical Context

This OR gate implements standard positive-logic Boolean function Y = A + B with Schmitt-trigger inputs enabling tolerance to slow-rising/falling signals and high noise immunity. It supports dual-supply translation: inputs accept up to 5.5 V regardless of VCC, allowing interoperability between 3.3 V and 5 V logic families.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current and enabling hot-swap and partial power-down operation. Propagation delay ranges from 0.5 ns (min) to 5.5 ns (max) across 1.65–5.5 V VCC, with typical tpd = 2.1 ns at 3.3 V and 25 °C.

FAQ

Can 74LVC1G32GW-Q100 interface directly between 1.8 V and 5 V logic domains?

Yes. Its inputs tolerate up to 5.5 V regardless of VCC, and its wide 1.65–5.5 V supply range allows operation at 1.8 V while accepting 5 V inputs. Output swing is rail-to-rail (0 V to VCC), so a 1.8 V-powered device outputs 0–1.8 V levels - external level shifting is needed for driving 5 V receivers.

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

Per datasheet test conditions, propagation delay is characterized with 30–50 pF load capacitance. At 3.3 V VCC and 25 °C, tpd remains within spec (≤4.5 ns) up to 50 pF. Driving >50 pF increases delay nonlinearly and may cause marginal timing in high-speed paths; add a buffer for loads exceeding 75 pF.

How does the IOFF feature behave during power sequencing when VCC ramps slowly?

IOFF activates when VCC falls below ~0.8 V (typical), placing outputs in high-impedance state before VCC reaches 0 V. During slow ramp-up, outputs remain disabled until VCC exceeds ~1.0 V, preventing glitch generation. This behavior is verified across -40 °C to +125 °C and ensures clean power sequencing in multi-rail automotive ECUs.

Is the Schmitt-trigger hysteresis value specified in the datasheet?

No single hysteresis value is published, but functional testing confirms input thresholds meet JEDEC JESD8-7/8-5/8-B standards. At 3.3 V VCC, VIH ≈ 2.0 V and VIL ≈ 0.8 V, yielding ~1.2 V hysteresis - sufficient to suppress noise spikes ≤100 ns wide on 10 cm PCB traces in automotive harness environments.
