Nexperia USA Inc. 74LVC1G32GV-Q100H

Overview

74LVC1G32GV-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. It serves as a level-translating combinational logic element in body control modules and sensor interface circuits.

For engineers reviewing the 74LVC1G32GV-Q100 datasheet, 74LVC1G32GV-Q100 pinout, 74LVC1G32GV-Q100 application, or 74LVC1G32GV-Q100 equivalent, key selection criteria include its overvoltage-tolerant 5.5 V inputs, Schmitt-trigger input hysteresis for noise immunity, IOFF leakage < ±2 μA during power-down, and SC-74A (SOT753) package compatibility with high-density PCB layouts.

Technical Context

This device implements standard positive-logic OR functionality (Y = A + B) with Schmitt-trigger inputs enabling robust operation under slow-rising or noisy signal conditions. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current and supporting hot-swap and partial-power-down system architectures.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8-B/JESD36 (2.7–3.6 V), ensuring interoperability across mixed-voltage domains. Propagation delay ranges from 0.5 ns (min) to 6.0 ns (max) at VCC = 3.0–3.6 V, with dynamic power dissipation capacitance CPD = 16 pF at VCC = 3.3 V.

FAQ

Can 74LVC1G32GV-Q100 operate with a 1.65 V supply while driving a 5 V load?

No-it cannot drive a 5 V load directly. Its output voltage swing is rail-to-rail (0 V to VCC), so at 1.65 V supply, VOH ≤ 1.55 V. However, its inputs tolerate up to 5.5 V, enabling it to receive 5 V signals while powered from 1.65–5.5 V rails-making it ideal for level translation into lower-voltage logic domains.

Does the IOFF feature require external control or enable pins?

No IOFF activation is automatic and unconditional: when VCC drops to 0 V, the internal IOFF circuit engages without any external signal, disabling outputs and limiting I/O leakage to < ±2 μA. This behavior is intrinsic to the silicon design and requires no configuration, pull-ups, or additional circuitry.

What is the maximum capacitive load this OR gate can drive reliably?

Per Nexperia's test conditions in Table 10, the device is characterized with CL = 30–50 pF loads. While not explicitly rated beyond 50 pF, its ±24 mA drive strength at 3.0 V supports stable switching into ≥100 pF loads at reduced edge rates-verified in application notes AN10751 and AN11017 for similar LVC1G gates.

How does Schmitt-trigger input action improve noise immunity in automotive environments?

Schmitt-trigger inputs provide hysteresis-typically ~0.3–0.4 V-so the rising and falling input thresholds differ. This prevents oscillation or false triggering caused by slow edges or EMI-induced noise on long harness traces, a critical requirement for reliable operation in high-noise engine compartments and chassis-mounted modules.
