Nexperia USA Inc. 74AUP2G38GM,125

Overview

74AUP2G38GM,125 from Nexperia is a low-power dual 2-input NAND gate with open-drain outputs, designed for level-shifting and wired-logic interfacing in battery-powered and space-constrained systems. It operates across 0.8 V to 3.6 V supply, features Schmitt-trigger inputs for noise immunity, supports partial power-down via IOFF, and delivers propagation delays as low as 0.9 ns at 3.3 V (CL = 5 pF). It is used in I²C bus pull-up coordination and mixed-voltage GPIO expansion.

For engineers reviewing the 74AUP2G38GM,125 datasheet, 74AUP2G38GM,125 pinout, 74AUP2G38GM,125 application, or 74AUP2G38GM,125 equivalent, this device is selected for ultra-low static current (≤1.4 μA), wide-VCC compatibility, open-drain flexibility enabling active-LOW wired-OR, and guaranteed operation from –40 °C to +125 °C in XQFN8 packaging.

Technical Context

This logic gate implements two independent NAND functions with open-drain outputs, allowing direct connection to shared bus lines without external pull-ups when implementing wired-AND or wired-OR topologies. Each input incorporates Schmitt-trigger hysteresis, ensuring clean switching even with slow-rising signals across the full 0.8–3.6 V VCC range.

The IOFF circuit actively disables output leakage during partial power-down, blocking backflow current when VCC = 0 V while inputs/outputs remain biased up to 3.6 V. Input tolerance to 3.6 V enables interfacing with higher-voltage controllers regardless of VCC setting.

FAQ

Can 74AUP2G38GM,125 drive a 10 kΩ pull-up resistor at 3.3 V?

Yes. With VOL ≤ 0.50 V at IO = 4.0 mA and VCC = 3.0 V, the device can sink ≥4 mA while staying within logic LOW thresholds. A 10 kΩ pull-up to 3.3 V draws only 0.33 mA, well within the 20 mA absolute maximum sink rating and compatible with the specified VOL performance across temperature.

Does the IOFF feature work when VCC is disconnected but inputs are biased to 1.8 V?

Yes. The IOFF circuit activates when VCC ≤ 0.2 V, disabling output FETs and limiting leakage to ±0.75 μA maximum-even if inputs or outputs are held at 1.8 V. This prevents back-current flow into a powered-down domain, satisfying JEDEC JESD78B Class II latch-up immunity requirements.

Is the XQFN8 (SOT902-2) package RoHS and REACH compliant?

Yes. Nexperia confirms full compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006 for the 74AUP2G38GM,125 in SOT902-2 packaging, including lead-free terminations, halogen-free molding compound, and conflict mineral–free supply chain documentation.

How does Schmitt-trigger input hysteresis improve performance in noisy environments?

Schmitt-trigger inputs provide ≥100 mV hysteresis (VIH − VIL) across all VCC levels, preventing multiple transitions on slowly rising/falling signals caused by EMI or crosstalk. This eliminates need for external RC filters in motor control feedback paths, industrial analog front-ends, and long-trace sensor interfaces.
