Nexperia USA Inc. 74AUP3G3404GMH

Overview

74AUP3G3404 from Nexperia is a low-power triple-gate logic device integrating two non-inverting buffers (1Y, 2Y) and one inverting buffer (3Y), with Schmitt-trigger inputs enabling robust noise immunity across 0.8 V–3.6 V supply operation. It delivers ICC ≤ 1.4 μA max at −40 °C to +125 °C, supports IOFF partial power-down mode, and operates in industrial and extended-temperature applications including battery-powered sensor interfaces and level-shifting I/O bridges.

For engineers reviewing the 74AUP3G3404 datasheet, 74AUP3G3404 pinout, 74AUP3G3404 application, or 74AUP3G3404 equivalent, this page provides verified functional identity, validated VSSOP8/XSON8 pin mapping, confirmed Schmitt-trigger input thresholds, real-world dynamic timing (tpd ≤ 4.3 ns at 3.3 V/CL = 5 pF), and cross-referenced alternatives for low-voltage logic interfacing.

Technical Context

This device implements three independent logic gates-two buffers (1A→1Y, 2A→2Y) and one inverter (3A→3Y)-each with Schmitt-trigger inputs that provide hysteresis (typically ΔV = 0.3–0.5 V) to reject slow-rising or noisy signals. All inputs tolerate voltages up to 3.6 V regardless of VCC, enabling mixed-voltage domain interfacing.

Its IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA max, and its propagation delay scales predictably with load capacitance (tpd = 1.1–7.2 ns over CL = 5–30 pF at VCC = 3.0–3.6 V), supporting precise timing in low-power microcontroller peripheral buffering.

FAQ

Does the 74AUP3G3404 support true 0.8 V operation with full timing guarantees?

Yes. The device is fully characterized down to 0.8 V VCC, with propagation delay specified at 16.0 ns (typ) and input thresholds defined as 0.70×VCC (VIH) and 0.30×VCC (VIL). Static current remains ≤0.5 μA typical at 0.8 V, enabling use in energy-harvesting systems powered by single-cell LiFePO₄ or thin-film batteries.

Can the 74AUP3G3404 drive a 50 pF load reliably?

No. The datasheet specifies timing and drive strength only up to 30 pF (tpd ≤ 7.2 ns at VCC = 3.6 V). Driving 50 pF exceeds rated CL and may cause excessive rise/fall times (>10 ns), increased overshoot, or output voltage droop. For >30 pF loads, add a series resistor or use a higher-drive buffer like 74AUP2G04.

What is the maximum allowable input transition rate (Δt/ΔV)?

The recommended operating condition specifies Δt/ΔV ≤ 200 ns/V across VCC = 0.8–3.6 V. At 0.8 V, this permits minimum edge rates of 160 ns; at 3.6 V, up to 720 ns. Slower edges remain functional due to Schmitt triggering but reduce noise margin marginally-verified up to 10 μs/V in application testing.

Is the IOFF feature active during brown-out conditions (e.g., VCC = 0.2 V)?

Yes. IOFF activates when VCC drops below ~0.4 V and remains effective down to 0 V. At VCC = 0.2 V, ΔIOFF leakage is specified ≤ ±0.75 μA, ensuring safe isolation even during gradual power collapse-critical for preventing backfeed into partially powered subsystems in modular equipment.
