Nexperia USA Inc. 74AUP3G0434GSX

Overview

74AUP3G0434 from Nexperia is a low-power triple-gate logic device integrating two Schmitt-trigger inverters (1A→1Y, 3A→3Y) and one non-inverting buffer (2A→2Y), operating across 0.8 V–3.6 V supply range with IOFF partial power-down support, <0.9 μA max ICC at 25 °C, and −40 °C to +125 °C temperature rating-used in battery-powered sensor interface and level-shifting I/O conditioning circuits.

For engineers reviewing the 74AUP3G0434 datasheet, 74AUP3G0434 pinout, 74AUP3G0434 application, or 74AUP3G0434 equivalent, this page delivers verified functional topology, validated XSON8 (SOT1203) package mapping, confirmed Schmitt-trigger input thresholds, IOFF leakage specs, and real-world use cases in ultra-low-power mixed-voltage signal routing.

Technical Context

The device implements three independent CMOS logic gates on a single die: two inverting channels with hysteresis (VIH/VIL differing by ≥0.4 V at VCC = 1.8 V) and one non-inverting channel-all sharing common VCC and GND. Each gate features rail-to-rail input tolerance up to 3.6 V independent of VCC.

IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA max over −40 °C to +125 °C, enabling hot-insertion and multi-rail partial power-down systems without external isolation.

FAQ

Does the 74AUP3G0434 support mixed-voltage operation where inputs exceed VCC?

Yes. All inputs tolerate voltages from 0 V to 3.6 V regardless of VCC setting (0.8 V–3.6 V), enabling direct interfacing with higher-voltage sensors or legacy logic without external clamping diodes or level shifters-verified per datasheet Table 6 and Section 2 features.

What is the maximum capacitive load the 74AUP3G0434 can drive while maintaining specified propagation delay?

The device is characterized up to 30 pF load capacitance. At VCC = 3.3 V, tPD remains ≤5.1 ns (max) for CL = 30 pF per Table 9-sufficient for driving multiple CMOS inputs or short PCB traces without signal integrity degradation.

How does the IOFF feature behave when VCC is ramping during power-up or power-down sequences?

IOFF activates when VCC falls below ~0.2 V, forcing outputs into high-impedance state before supply collapse. During power-up, outputs remain disabled until VCC exceeds ~0.5 V-preventing glitch generation and bus contention during brown-out conditions as confirmed in Section 1 and Table 8 ΔIOFF specs.

Can the 74AUP3G0434 replace standard 74AUP1G04 or 74AUP1G07 in existing designs?

Only with layout and signal routing changes: the 74AUP3G0434 integrates three functions in one XSON8 package with fixed pinout (1A/3Y/VCC/2Y/2A/3A/GND/1Y). It cannot be drop-in substituted for single-gate variants but reduces total component count and improves system-level power efficiency in new designs.
