Nexperia USA Inc. 74AUP3G3404GFX

Overview

74AUP3G3404 from Nexperia is a low-power triple-gate logic device integrating two non-inverting buffers (1A→1Y, 3A→3Y) and one inverting buffer (2A→2Y), featuring Schmitt-trigger inputs for noise immunity across 0.8 V–3.6 V supply range, ICC ≤ 1.4 μA at +125 °C, IOFF-enabled partial power-down protection, and operation from –40 °C to +125 °C. It serves in voltage-level translation, signal conditioning, and noise-prone sensor interface circuits in portable and battery-powered systems.

For engineers reviewing the 74AUP3G3404 datasheet, 74AUP3G3404 pinout, 74AUP3G3404 application, or 74AUP3G3404 equivalent, key selection criteria include its dual-buffer + single-inverter topology, Schmitt-trigger input thresholds, sub-1.5 μA max ICC over full temperature range, IOFF leakage < ±0.75 μA during power-down, and compatibility with 0.8 V–3.6 V I/O domains in space-constrained industrial and IoT edge nodes.

Technical Context

This device implements three independent logic gates in a single 8-terminal package: two identical non-inverting buffers and one inverting buffer, each with Schmitt-trigger inputs ensuring robust switching despite slow-rising or noisy signals. All inputs tolerate up to 3.6 V regardless of VCC, enabling mixed-voltage interfacing.

IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA and supporting hot-insertion and partial system power-down. Propagation delay ranges from 1.0 ns (VCC = 3.6 V, CL = 5 pF) to 20.9 ns (VCC = 1.2 V, CL = 30 pF), with CPD = 4.0 pF at 3.6 V enabling precise dynamic power estimation.

FAQ

What is the maximum allowable input voltage when VCC = 0 V?

The 74AUP3G3404 allows input voltages up to 3.6 V even when VCC = 0 V, thanks to integrated input clamping diodes and IOFF circuitry. This enables safe hot-plug operation in modular systems where signal lines may be active before power is applied, with input clamping current limited to ±50 mA per Absolute Maximum Ratings table.

Does the device support true bidirectional signal translation?

No-the 74AUP3G3404 is unidirectional: inputs (1A/2A/3A) drive corresponding outputs (1Y/2Y/3Y) with fixed logic functions (non-inverting for 1A/3A, inverting for 2A). It does not implement bus-switch or auto-direction sensing; for bidirectional level translation, discrete MOSFET-based solutions or dedicated translators like NXSA1040 must be used.

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

Schmitt-trigger inputs provide hysteresis (typically ~0.1 V at 1.8 V), meaning the rising threshold (VIH) is higher than the falling threshold (VIL). This prevents multiple output transitions caused by slow-rising edges or noise spikes near the switching point-critical for reliable debouncing of mechanical switches or interpreting low-SNR analog sensor outputs without software intervention.

Can the 74AUP3G3404 drive a 50 pF capacitive load reliably?

While not characterized beyond 30 pF in the datasheet, the device can drive 50 pF loads at reduced speed: propagation delay increases approximately linearly with load capacitance. At VCC = 3.3 V, tpd scales from ~4.5 ns (30 pF) to ~7.5 ns (50 pF), remaining functional but requiring timing margin verification in high-speed clock distribution or data strobe paths.
