Nexperia USA Inc. 74AUP3G0434DCH

Overview

74AUP3G0434 from Nexperia is a low-power triple-gate logic device integrating two Schmitt-trigger inverters and one non-inverting buffer, operating across 0.8 V to 3.6 V supply range. It delivers ultra-low static current (≤1.4 μA at −40 °C to +125 °C), IOFF-enabled partial power-down protection, and robust noise immunity for signal conditioning in battery-powered sensor interfaces and level-shifting I/O buffers.

For engineers reviewing the 74AUP3G0434 datasheet, 74AUP3G0434 pinout, 74AUP3G0434 application, or 74AUP3G0434 equivalent, key selection criteria include its dual-Schmitt input tolerance for slow-rising signals, guaranteed operation down to 0.8 V, IOFF leakage < ±0.75 μA during power-down, and VSSOP8/XSON8 package compatibility with high-density PCB layouts.

Technical Context

This device implements three independent logic gates in a single 8-pin package: two inverting channels (1A→1Y, 2A→2Y) with Schmitt-trigger inputs and one non-inverting channel (3A→3Y) also with Schmitt-trigger input. All inputs accept up to 3.6 V regardless of VCC, enabling mixed-voltage interfacing.

Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±20 mA per I/O, while maintaining input/output voltage tolerance from −0.5 V to +4.6 V - critical for hot-swap and partial-power-down system architectures.

FAQ

Does the 74AUP3G0434 support true bidirectional signal translation?

No. It is a unidirectional logic device: inputs (1A, 2A, 3A) accept signals up to 3.6 V regardless of VCC, but outputs (1Y, 2Y, 3Y) swing only between GND and the applied VCC. It cannot translate from high-VCC to low-VCC domains in reverse direction.

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

The device is characterized up to 30 pF load capacitance. At VCC = 3.3 V, tpd remains ≤5.1 ns with CL = 30 pF. Driving >30 pF may increase propagation delay nonlinearly and raise dynamic power; external series termination is recommended beyond this limit.

Can the 74AUP3G0434 be used with VCC = 0 V while signals are applied to inputs/outputs?

Yes - the IOFF feature ensures outputs are high-impedance and input clamping diodes remain inactive when VCC = 0 V. Input/output pins tolerate −0.5 V to +4.6 V under this condition, with leakage limited to ±0.75 μA, satisfying JEDEC JESD78B Class II latch-up immunity.

How does the Schmitt trigger hysteresis vary with supply voltage?

Hysteresis is proportional to VCC: typical ΔV = 0.15 × VCC. At VCC = 1.2 V, hysteresis is ~180 mV; at VCC = 3.3 V, it is ~495 mV. This ensures consistent noise margin percentage (≥15%) across the full 0.8–3.6 V operating range.
