Nexperia USA Inc. 74HC2G32DC-Q100H

Overview

74HC2G32DC-Q100 from Nexperia is a dual 2-input OR gate in VSSOP8 package, qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0 V to 6.0 V and CMOS-level inputs. It delivers propagation delay as low as 7.0 ns at VCC = 6.0 V and supports high noise immunity with latch-up performance exceeding 100 mA per JESD78 Class II Level B.

For engineers reviewing the 74HC2G32DC-Q100 datasheet, 74HC2G32DC-Q100 pinout, 74HC2G32DC-Q100 application, or 74HC2G32DC-Q100 equivalent, this device serves as a robust logic building block in automotive body control modules, infotainment power sequencing, and ADAS sensor interface signal conditioning where rail-to-rail input compatibility and temperature-stable timing are required.

Technical Context

This device implements two independent OR logic functions with Schmitt-trigger–free inputs and push-pull outputs. Each gate accepts CMOS-level input thresholds (VIH = 4.2 V min at VCC = 6.0 V; VIL = 1.8 V max), enabling direct interfacing with microcontroller GPIOs and other HC-family logic without level translation.

Its static output drive capability supports ±4.0 mA at VCC = 4.5 V (VOH ≥ 4.18 V, VOL ≤ 0.26 V), while dynamic characteristics include 10 pF typical power dissipation capacitance (CPD) and transition times as fast as 5 ns at VCC = 6.0 V, ensuring reliable operation in mixed-signal automotive subsystems.

FAQ

Is 74HC2G32DC-Q100 pin-compatible with 74HCT2G32DC-Q100?

Yes, both share identical VSSOP8 (SOT765-1) pinout and mechanical footprint. The only functional difference lies in input threshold levels: HC uses CMOS-compatible VIH/VIL, while HCT uses TTL-compatible thresholds. No PCB redesign is needed when swapping between them, though system-level logic level validation is required.

What is the maximum capacitive load this device can drive reliably?

The datasheet specifies guaranteed output drive of ±4.0 mA at VCC = 4.5 V with VOL ≤ 0.26 V and VOH ≥ 4.18 V. Based on typical CPD = 10 pF and measured transition times, it reliably drives ≤50 pF total load (including trace and input capacitance) while maintaining <22 ns propagation delay across temperature.

Does this part support 3.3 V-only operation in automotive systems?

Yes - the 2.0–6.0 V supply range fully covers 3.3 V nominal systems. At VCC = 3.3 V, VIH is guaranteed ≥2.31 V and VIL ≤ 1.32 V (interpolated from datasheet tables), providing >1.0 V noise margin. It is widely deployed in 3.3 V automotive domains including instrument clusters and telematics control units.

How does the input clamping diode affect external circuit design?

The integrated clamp diodes allow inputs to safely tolerate voltages up to VCC + 0.5 V or down to GND − 0.5 V, provided input current is limited to ±20 mA. This enables direct connection to higher-voltage sensors or buses using simple series resistors (e.g., 10 kΩ for 12 V signals), eliminating external TVS or Schottky diodes in many cases.
