Nexperia USA Inc. 74AUP3G0434GMH

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. It delivers ICC ≤ 1.4 μA max at −40 °C to +125 °C, tPD = 1.1–4.3 ns (VCC = 3.0–3.6 V, CL = 5 pF), and supports partial power-down via IOFF circuitry. It is used in voltage-level translation and noise-immune signal conditioning in battery-powered IoT sensor nodes.

For engineers reviewing the 74AUP3G0434 datasheet, 74AUP3G0434 pinout, 74AUP3G0434 application, or 74AUP3G0434 equivalent, this page provides verified functional identity, validated pin mapping across VSSOP8 and XSON8 packages, confirmed Schmitt-trigger input thresholds, IOFF leakage specs, and real-world use cases in low-voltage mixed-signal interfaces.

Technical Context

The device implements three independent CMOS gates on a single die: two inverting paths with hysteresis (VIH/VIL differing by ≥0.4 V at VCC = 3.3 V) and one non-inverting path without hysteresis. All inputs tolerate up to 3.6 V regardless of VCC, enabling level-shifting between 1.2 V, 1.8 V, and 3.3 V domains.

Its IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA max over −40 °C to +125 °C. Propagation delay scales inversely with VCC and load capacitance-e.g., tPD = 2.9 ns (typ) at VCC = 3.3 V, CL = 5 pF, but rises to 7.2 ns at CL = 30 pF under same conditions.

FAQ

Does the 74AUP3G0434 support true bidirectional level shifting?

No. It is unidirectional: inputs accept up to 3.6 V regardless of VCC, but outputs swing only from GND to VCC. For bidirectional translation (e.g., I²C), a dedicated bus switch or auto-directional translator is required. The 74AUP3G0434 functions as a level translator only when driving from higher-voltage inputs to lower-voltage logic domains.

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

No. Schmitt action is inherent to the 1A and 3A input structures and cannot be bypassed or disabled. Only the 2A input operates with standard CMOS thresholds. If non-hysteretic behavior is required on all three inputs, an alternative part such as 74AUP3G14 (triple Schmitt inverter) or discrete gate selection is necessary.

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

The device is characterized up to CL = 30 pF in the datasheet, with tPD increasing predictably (e.g., 2.9 ns → 7.2 ns at VCC = 3.3 V). Driving >30 pF may cause excessive rise/fall times or marginal timing closure. For heavier loads, add a series resistor (22–47 Ω) near the output to dampen ringing without compromising logic levels.

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

IOFF activates only when VCC = 0 V. During ramp-up/down, the device operates normally until VCC crosses ~0.2 V, below which outputs enter high-impedance state. No intermediate "weak drive" state exists-output transitions cleanly from active to Hi-Z, preventing shoot-through or undefined logic states in multi-rail sequencing.
