Nexperia USA Inc. 74AUP1T32GWH

Overview

74AUP1T32GWH from Nexperia is a single 2-input OR gate with integrated voltage-level translation, designed for bidirectional logic interfacing between 1.8 V and 2.5/3.3 V domains. It operates across 2.3 V–3.6 V supply, delivers ≤1.5 μA max ICC, features Schmitt-trigger inputs for noise immunity, and supports partial power-down via IOFF circuitry. It is used in battery-powered IoT sensor nodes requiring robust level-shifting and ultra-low static power.

For engineers reviewing the 74AUP1T32GWH datasheet, 74AUP1T32GWH pinout, 74AUP1T32GWH application, or 74AUP1T32GWH equivalent, this page provides verified functional identity, validated TSSOP5 pin mapping, confirmed level-translation behavior (1.8 V input compatible at 2.5/3.3 V VCC), real-world propagation delay (≤5.0 ns @ CL = 5 pF, VCC = 2.3 V), and precise thermal operating range (−40 °C to +125 °C).

Technical Context

This device implements a single 2-input positive-logic OR function with Schmitt-trigger inputs enabling tolerance to slow-rising/falling signals across its full 2.3 V–3.6 V VCC range. Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V.

The input threshold voltages (VT+ = 0.60–1.19 V, VT− = 0.33–0.85 V) and hysteresis (VH = 0.10–0.60 V) are specified over −40 °C to +125 °C, ensuring reliable switching with 1.8 V CMOS inputs while powered from 2.5 V or 3.3 V supplies.

FAQ

Does 74AUP1T32GWH support true bidirectional level translation?

No-it performs unidirectional logic-level translation: 1.8 V inputs are accepted, but the output swings from GND to VCC (2.5 V or 3.3 V). It does not translate from high-voltage to low-voltage domains. For bidirectional translation (e.g., I²C), a dedicated bus buffer like PCA9306 is required.

Can Pin 1 (B) and Pin 2 (A) accept different input voltage domains simultaneously?

Yes-both inputs tolerate up to 3.6 V regardless of VCC, allowing one input to be driven from a 1.8 V domain and the other from a 3.3 V domain while VCC = 2.5 V. This enables flexible inter-domain signal combining without external resistors or clamps.

What is the maximum capacitive load the 74AUP1T32GWH output can drive reliably?

The output is characterized up to 30 pF (see Table 8), with tpd increasing predictably: 5.0 ns @ 5 pF, 8.0 ns @ 30 pF (VCC = 2.3 V). Driving >30 pF may cause timing violations or increased dynamic power; for heavier loads, add a buffer stage or reduce trace length.

Is the 74AUP1T32GWH pin-compatible with the 74AUP1T32GW variant?

Yes-both share identical TSSOP5 (SOT353-1) pinout, electrical specifications, and marking code "5B". The "H" suffix denotes tape-and-reel packaging per AEC-Q200-compliant handling; no functional or parametric difference exists between GW and GWH.
