Nexperia USA Inc. 74LVC2G32DC-Q100H

Overview

74LVC2G32DC-Q100 from Nexperia is a dual 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, 5 V-tolerant inputs, ±24 mA output drive at V_CC = 3.0 V, and IOFF-enabled partial power-down protection.

For engineers reviewing the 74LVC2G32DC-Q100 datasheet, 74LVC2G32DC-Q100 pinout, 74LVC2G32DC-Q100 application, or 74LVC2G32DC-Q100 equivalent, this device serves as a level-translating OR gate in mixed-voltage automotive subsystems-especially where Schmitt-trigger noise immunity, low static current (<4 μA), and guaranteed operation up to 125 °C are required.

Technical Context

This device implements two independent OR logic functions (1A/1B→1Y, 2A/2B→2Y) with Schmitt-trigger inputs enabling robust operation with slow-rising signals and high noise immunity. Each gate supports rail-to-rail input voltage tolerance up to 5.5 V regardless of V_CC, allowing seamless interfacing between 3.3 V and 5 V domains.

The IOFF circuit actively disables outputs during power-down, blocking backflow current when V_CC = 0 V, while maintaining ≤±2 μA power-off leakage. Propagation delay ranges from 0.7 ns (V_CC = 5.5 V) to 11 ns (V_CC = 1.65 V, T_amb = 85 °C), with CPD = 14 pF per gate for dynamic power estimation.

FAQ

Can 74LVC2G32DC-Q100 operate with V_CC = 1.8 V while accepting 5 V inputs?

Yes. The device supports V_CC from 1.65 V to 5.5 V and tolerates input voltages up to 5.5 V regardless of supply level. At V_CC = 1.8 V, VIH is 0.65 × V_CC ≈ 1.17 V and VIL is 0.35 × V_CC ≈ 0.63 V, enabling reliable detection of 5 V TTL/CMOS signals without external clamping.

What is the maximum output current per pin at V_CC = 5.0 V?

Per datasheet Table 7, the device delivers VOH ≥ 4.1 V and VOL ≤ 0.55 V at IO = ±32 mA with V_CC = 4.5 V. At V_CC = 5.0 V, output drive remains within ±32 mA limits, with typical VOH > 4.3 V and VOL < 0.45 V - verified across -40 °C to +125 °C.

Does the IOFF feature disable both outputs simultaneously during power-down?

Yes. When V_CC = 0 V, the IOFF circuitry places both 1Y and 2Y outputs in high-impedance state, limiting leakage to ≤±2 μA per output terminal. This behavior is tested and guaranteed per AEC-Q100 stress requirements for partial power-down operation.

How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?

Schmitt-trigger inputs provide hysteresis: VIH (≈1.7–2.0 V depending on V_CC) and VIL (≈0.7–0.8 V) differ by ≥0.9 V, rejecting noise spikes <0.9 V peak-to-peak. This prevents false toggling on slow or noisy signals from switches, sensors, or long PCB traces - confirmed in functional testing per IEC 61000-4-2/4-4.
