Nexperia USA Inc. 74AUP3G0434GTX

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 identity, package-specific pin mapping, Schmitt-trigger noise immunity specs, IOFF leakage values, and direct alternative comparisons for low-voltage mixed-signal board design.

Technical Context

The device implements three independent CMOS logic gates on a single die: two inverting paths with hysteresis (VIH/VIL thresholds vary per VCC tier, e.g., 0.65VCC/0.35VCC at 0.9–1.95 V) and one non-inverting path without hysteresis. All inputs tolerate up to 3.6 V regardless of VCC, enabling robust level translation between disparate voltage domains.

IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA max over −40 °C to +125 °C, satisfying JEDEC JESD78B Class II latch-up immunity (>100 mA). Propagation delay ranges from 1.1 ns (VCC = 3.6 V, CL = 5 pF) to 33.6 ns (VCC = 0.8 V, CL = 30 pF), with CPD = 4.0 pF at 3.6 V.

FAQ

Does the 74AUP3G0434 support true bidirectional signal routing?

No. The device contains three unidirectional logic gates: two inverters (1A→1Y, 3A→3Y) and one buffer (2A→2Y). It lacks bus-switch or transmission-gate architecture required for bidirectional data flow. Each path operates strictly input-to-output with fixed polarity and directionality.

Can the Schmitt-trigger inputs be disabled to use standard CMOS thresholds?

No. Schmitt-trigger action is inherent to the input structure of the inverter sections (1A and 3A) and cannot be bypassed or configured. The buffer input (2A) uses standard CMOS thresholds without hysteresis, providing a non-inverting path with conventional VIH/VIL levels.

What is the maximum capacitive load the 74AUP3G0434 can drive reliably?

The device is characterized up to 30 pF load capacitance per output, with propagation delay increasing predictably (e.g., 1.1 ns at 5 pF → 7.2 ns at 30 pF, VCC = 3.6 V). Driving >30 pF may cause excessive rise/fall times or marginal timing closure but will not damage the part.

Is the 74AUP3G0434 qualified for automotive applications per AEC-Q100?

No. While rated for −40 °C to +125 °C operation and meeting JEDEC latch-up and ESD standards, the 74AUP3G0434 is not AEC-Q100 qualified. Nexperia explicitly states in its legal disclaimers that non-automotive-qualified products are unsuitable for safety-critical automotive use without additional customer validation.
