Nexperia USA Inc. 74LVC1G332GV-Q100H

Overview

74LVC1G332GV-Q100 from Nexperia is a single 3-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 V_CC = 3.0 V, and Schmitt-trigger inputs enabling robust noise immunity in mixed-voltage systems.

For engineers reviewing the 74LVC1G332GV-Q100 datasheet, 74LVC1G332GV-Q100 pinout, 74LVC1G332GV-Q100 application, or 74LVC1G332GV-Q100 equivalent, this device serves as a voltage-tolerant level translator and logic combiner in automotive body control modules, infotainment power sequencing, and sensor interface signal conditioning where partial power-down capability and IOFF protection are required.

Technical Context

This device implements standard positive-logic OR functionality (Y = A + B + C) with Schmitt-trigger inputs that accept slow-rising signals and tolerate overvoltage up to 5.5 V regardless of V_CC. Its IOFF circuitry actively disables outputs during power-down, preventing backflow current when V_CC = 0 V.

It supports dual-supply translation between 3.3 V and 5 V domains while maintaining CMOS low-power operation (ICC ≤ 4 μA), JEDEC-compliant voltage thresholds across multiple V_CC ranges, and ESD robustness per HBM (>2000 V) and CDM (>1000 V) standards.

Key Specifications

Pinout & Package

FAQ

What is the maximum input voltage the 74LVC1G332GV-Q100 can tolerate?

The inputs are overvoltage tolerant up to 5.5 V regardless of V_CC level, as confirmed in Table 5 (Limiting Values) and Section 2 features. This allows safe interfacing with 5 V sensors or legacy peripherals even when V_CC is 1.8 V or 3.3 V, without external clamping or level-shifting circuitry.

Does the 74LVC1G332GV-Q100 support partial power-down operation?

Yes - its IOFF circuitry disables the output when V_CC = 0 V, preventing backflow current through powered-down sections of the system. This behavior is explicitly specified in Section 1 (General description) and validated per AEC-Q100 requirements for automotive power sequencing.

How does the Schmitt-trigger input improve system reliability?

Schmitt-trigger action provides hysteresis (~0.3 × V_CC) at each input, increasing noise immunity and eliminating false triggering from slow-rising signals or EMI on long traces. This is critical in automotive harness environments where signal integrity is compromised by switching noise and temperature variation.

What is the typical propagation delay at 3.3 V supply?

At V_CC = 3.3 V and T_amb = 25 °C, typical propagation delay (t_pd) is 2.6 ns (Table 8, V_CC = 3.0 V to 3.6 V row). Measured values range from 1.0 ns (min) to 6.2 ns (max) across –40 °C to +125 °C, ensuring predictable timing in real-world automotive thermal conditions.
