NXP Semiconductors 74AUP2G38GD,125

Overview

74AUP2G38GD,125 from Nexperia is a low-power dual 2-input NAND gate with open-drain outputs, designed for level-shifting and wired-OR logic in ultra-low-voltage systems. It operates across 0.8 V to 3.6 V, features Schmitt-trigger inputs for noise immunity, supports partial power-down via IOFF, and delivers ICC ≤ 1.4 μA at −40 °C to +125 °C - enabling use in battery-powered IoT sensor nodes and portable medical monitors.

For engineers reviewing the 74AUP2G38GD,125 datasheet, 74AUP2G38GD,125 pinout, 74AUP2G38GD,125 application, or 74AUP2G38GD,125 equivalent, this device is selected for its sub-1-μA static current, robust 0.8 V logic compatibility, open-drain flexibility for mixed-voltage bus interfacing, and guaranteed operation up to +125 °C in space-constrained industrial control modules.

Technical Context

The 74AUP2G38GD,125 implements two independent NAND gates, each with Schmitt-trigger inputs that tolerate slow edge rates (up to 200 ns/V) and maintain consistent switching thresholds across the full 0.8–3.6 V supply range. Its open-drain outputs enable active-LOW wired-OR and active-HIGH wired-AND configurations without external pull-ups when shared with compatible devices.

IOFF circuitry actively disables output leakage during partial power-down (VCC = 0 V), limiting backflow current to ±0.75 μA - critical for hot-swap and multi-rail system integrity. Input tolerance up to 3.6 V allows interfacing with higher-voltage controllers while powered from lower VCC rails.

FAQ

What is the maximum capacitive load the 74AUP2G38GD,125 can drive reliably?

The device is characterized up to 30 pF load capacitance across all VCC levels (0.8 V–3.6 V), with propagation delay increasing predictably - e.g., 7.8 ns at 3.3 V/15 pF and 15.3 ns at 3.3 V/30 pF. Driving loads >30 pF risks timing violations and increased dynamic power; external buffer stages are recommended beyond this limit.

Can the 74AUP2G38GD,125 be used with a 0.8 V supply and 3.3 V inputs?

Yes - inputs tolerate up to 3.6 V regardless of VCC, so 3.3 V signals may safely drive the device powered at 0.8 V. The Schmitt-trigger inputs ensure clean logic transitions, and the IOFF feature remains active even when VCC is below 0.8 V during power sequencing.

Does the 74AUP2G38GD,125 support hot-swap insertion in live backplanes?

Yes - the IOFF circuitry guarantees output disable and leakage ≤ ±0.75 μA when VCC = 0 V, preventing back-current flow into powered downstream circuits. This meets IEC 61000-4-2 Level 4 ESD immunity requirements and enables safe insertion into live 3.3 V or 5 V backplanes.

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

Schmitt-trigger inputs provide ≥100 mV hysteresis, meaning the rising threshold (VIH) is ~100 mV higher than the falling threshold (VIL). This prevents multiple toggles on slow or noisy edges - such as those from long PCB traces near motors or switching regulators - ensuring one clean transition per input event.
