Nexperia USA Inc. 74AUP1T32GXH

Overview

74AUP1T32GXH from Nexperia is a single 2-input OR gate with integrated voltage-level translation, designed for mixed-voltage logic interfacing between 1.8 V inputs and 2.5 V/3.3 V supply domains. It operates across 2.3 V–3.6 V, 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 level-shifted signal aggregation.

For engineers reviewing the 74AUP1T32GXH datasheet, 74AUP1T32GXH pinout, 74AUP1T32GXH application, or 74AUP1T32GXH equivalent, key selection criteria include its 5-terminal X2SON5 package, 2.3–3.6 V supply range, IOFF-enabled power-down behavior, Schmitt-trigger input thresholds (VT+ = 0.75–1.19 V), and propagation delay down to 1.1 ns at 3.3 V/CL = 5 pF.

Technical Context

This device implements a single 2-input positive-logic OR function with hysteresis-enabled Schmitt-trigger inputs (VT− = 0.33–0.85 V, VT+ = 0.60–1.19 V) to tolerate slow-rising signals across its full temperature range (−40 °C to +125 °C). Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

The logic core is built on ultra-low-power AUP (Advanced Ultra-low-power) CMOS technology, enabling static current as low as 0.6 μA at 2.5 V and dynamic power dissipation governed by CPD = 4–5 pF. Input voltage tolerance up to 3.6 V allows direct connection to higher-voltage sources without external clamping.

FAQ

What is the maximum input voltage the 74AUP1T32GXH can tolerate?

The 74AUP1T32GXH accepts input voltages up to 3.6 V regardless of VCC setting, enabling direct interface with higher-voltage peripherals without external clamping diodes or resistors. This is confirmed in Table 5 (Limiting Values) and Table 6 (Recommended Operating Conditions) of the official Nexperia datasheet Rev. 4.

Does the 74AUP1T32GXH support true bidirectional level translation?

No - the 74AUP1T32GXH is unidirectional: inputs accept 1.8 V logic levels while the output swings rail-to-rail at the VCC voltage (2.5 V or 3.3 V). It does not translate output signals back to lower voltages; it is a level-translating OR gate, not a bus switch or bidirectional translator.

How does the IOFF feature behave when VCC is ramping or partially powered?

IOFF activates only when VCC is fully at 0 V; during power-up/down transitions, the device operates normally. The IOFF circuit does not engage at intermediate VCC levels - it is not a supply-monitoring feature but a hard power-off isolation mechanism verified per JESD78 Class II latch-up testing.

Can the 74AUP1T32GXH drive a 50 pF load reliably?

While not characterized beyond 30 pF in the datasheet, the output drive strength (±4 mA at 3.3 V) supports 50 pF loads with increased propagation delay (~12–15 ns) and slightly degraded edge rates. For production use at 50 pF, derating analysis per Figure 4 and Table 8 is required - Nexperia specifies performance only up to 30 pF.
