Nexperia USA Inc. 74AUP2G38DC,125

Overview

74AUP2G38DC,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 mixed-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 is rated for −40 °C to +125 °C operation in VSSOP8 packaging.

For engineers reviewing the 74AUP2G38DC,125 datasheet, 74AUP2G38DC,125 pinout, 74AUP2G38DC,125 application, or 74AUP2G38DC,125 equivalent, this device is selected for ultra-low static current (≤1.4 μA), open-drain bus arbitration, I²C-compatible pull-up interfaces, and robust ESD protection (HBM >5 kV) in space-constrained industrial and portable electronics.

Technical Context

The 74AUP2G38DC implements two independent NAND gates, each with open-drain output enabling active-LOW wired-OR or active-HIGH wired-AND logic when connected to external pull-ups. Its Schmitt-trigger inputs tolerate slow edge rates (up to 200 ns/V) and maintain consistent switching thresholds across the full 0.8 V–3.6 V supply range.

IOFF circuitry disables both outputs during power-down, blocking backflow current when VCC = 0 V while inputs/outputs remain biased up to 3.6 V. Static power consumption remains ≤1.4 μA at +125 °C, and dynamic performance delivers propagation delays as low as 0.8 ns (VCC = 3.3 V, CL = 5 pF).

FAQ

Can 74AUP2G38DC,125 drive an I²C bus directly?

Yes - its open-drain outputs and 3.6 V-tolerant inputs allow direct connection to I²C SDA/SCL lines. Use a single pull-up resistor per line (e.g., 2.2 kΩ to 3.3 V), and ensure VCC matches the lowest logic domain on the bus. Propagation delay <0.9 ns avoids timing violations even at 1 MHz clock rates.

Does the IOFF feature work when VCC = 0 V but inputs are pulled to 3.3 V?

Yes - IOFF activates when VCC drops below ~0.2 V, disabling both outputs and limiting leakage to ±0.75 μA even with inputs or outputs held at 3.6 V. This prevents back-current damage during hot-plug events or asymmetric power sequencing in multi-rail systems.

What is the maximum capacitive load the outputs can drive reliably?

The outputs are characterized up to 30 pF load capacitance. At VCC = 3.3 V and CL = 30 pF, tpd remains ≤15.3 ns (max), and VOL stays ≤0.50 V at 4 mA sink. For loads >30 pF, add a series resistor (e.g., 10–33 Ω) near the driver to damp ringing without compromising rise/fall time.

How does Schmitt-trigger input action improve noise immunity?

Schmitt-trigger inputs provide hysteresis: VIH is typically 2.0 V and VIL is 0.36 V at VCC = 3.0 V, yielding a 1.64 V threshold window. This rejects noise spikes <1.6 V peak-to-peak and tolerates slow input edges (up to 200 ns/V), preventing false triggering on EMI-coupled or mechanically generated signals.
