Nexperia USA Inc. 74AUP1T34GF,132

Overview

74AUP1T34GF,132 from Nexperia is a single-channel dual-supply translating buffer with independent VCC(A) and VCC(Y) rails (1.1 V to 3.6 V), Schmitt-trigger input for noise immunity, IOFF-enabled partial power-down protection, and guaranteed operation from −40 °C to +125 °C in a 5-pin XSON package (SOT1226-3). It enables level translation between disparate voltage domains in ultra-low-power IoT sensor nodes and battery-powered microcontroller peripherals.

For engineers reviewing the 74AUP1T34GF,132 datasheet, 74AUP1T34GF,132 pinout, 74AUP1T34GF,132 application, or 74AUP1T34GF,132 equivalent, this device delivers verified dual-rail translation with sub-1 µA static ICC, <5 ns propagation delay at 3.3 V, and robust ESD protection (HBM >5 kV), making it critical for mixed-voltage interface design where supply sequencing and back-drive prevention are mandatory.

Technical Context

The 74AUP1T34GF,132 implements a unidirectional A→Y buffer with separate supply references: input logic threshold tracks VCC(A), while output swing and drive strength scale with VCC(Y). Its Schmitt-trigger input provides hysteresis (typically 0.2 × VCC(A)), enabling reliable operation with slow-rising signals from RC networks or low-speed GPIOs.

IOFF circuitry actively disables the Y output when either VCC(A) or VCC(Y) is near 0 V, blocking reverse current flow and preventing bus contention during power-state transitions-essential for hot-swap and multi-rail system partitioning.

FAQ

Can 74AUP1T34GF,132 translate from 3.3 V to 1.2 V while maintaining valid logic levels?

Yes. When VCC(A) = 3.3 V and VCC(Y) = 1.2 V, the input accepts standard 3.3 V CMOS levels (VIH ≥ 2.0 V, VIL ≤ 0.9 V), and the output drives valid 1.2 V logic (VOH ≥ 1.1 V at –1.1 mA, VOL ≤ 0.36 V at 1.1 mA), satisfying JEDEC JESD8-7 compliance for 1.2 V systems.

What happens to the Y output when VCC(Y) = 0 V but VCC(A) = 3.3 V?

The IOFF circuit activates, forcing the Y output into a high-impedance state with leakage ≤ ±0.2 µA. This prevents back-driving of the VCC(Y) rail, protecting downstream 3.3 V logic from unintended current injection during power sequencing or fault conditions.

Is the Schmitt-trigger input compatible with open-drain or push-pull sources?

Yes. The Schmitt-trigger input functions identically with both source types. Its hysteresis (≈0.2 × VCC(A)) rejects noise regardless of driver topology, and its input leakage (±0.1 µA max) imposes negligible load on weak open-drain pull-ups or high-impedance analog sources.

Does 74AUP1T34GF,132 require external decoupling capacitors?

Yes. A 100 nF ceramic capacitor is recommended between each VCC pin and GND, placed within 2 mm of the respective pin. This stabilizes local supply impedance during fast output transitions and maintains specified tPD and noise immunity performance per JEDEC guidelines.
