Nexperia USA Inc. 74AUP1T87GWH

Overview

74AUP1T87GWH from Nexperia is a single 2-input EXCLUSIVE-NOR gate with integrated voltage-level translation, operating from 2.3 V to 3.6 V supply and accepting 1.8 V CMOS input levels. It delivers ultra-low static current (≤1.5 μA), Schmitt-trigger inputs for noise immunity, and IOFF circuitry for partial power-down protection. It is used in battery-powered IoT sensor interfaces where level-shifting between 1.8 V logic and 3.3 V domains is required.

For engineers reviewing the 74AUP1T87GWH datasheet, 74AUP1T87GWH pinout, 74AUP1T87GWH application, or 74AUP1T87GWH equivalent, key selection criteria include its 5-pin TSSOP5 package, 2.3–3.6 V supply range, sub-1.5 μA ICC, Schmitt-trigger hysteresis (0.15–0.60 V), and IOFF-enabled safe power sequencing in mixed-voltage systems.

Technical Context

The 74AUP1T87GWH implements a single EXNOR logic function with dual-voltage tolerance: inputs accept up to 3.6 V regardless of VCC, enabling robust interfacing between disparate logic families. Its Schmitt-trigger inputs provide hysteresis (VT+ − VT− = 0.15–0.60 V) across all operating temperatures and supply voltages, ensuring reliable switching despite slow-rising signals.

IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA and enabling hot-swap and partial power-down operation. The device is fully characterized from −40 °C to +125 °C and supports dynamic operation up to 11.9 ns propagation delay (CL = 30 pF, VCC = 2.3 V).

FAQ

Can the 74AUP1T87GWH translate from 3.3 V inputs down to a 2.5 V supply domain?

Yes. The device accepts input voltages up to 3.6 V regardless of VCC, so a 3.3 V input signal applied to A or B will correctly drive the EXNOR function when VCC = 2.5 V. Output swing will be referenced to the 2.5 V rail, with VOH ≥ 2.4 V and VOL ≤ 0.33 V under 2.3 mA load, per datasheet Table 7.

Does the IOFF feature activate automatically when VCC drops below a threshold?

No. IOFF is not voltage-threshold triggered - it activates only when VCC reaches 0 V (or near-zero). The datasheet specifies IOFF leakage (±0.75 μA) explicitly at VCC = 0 V. Below nominal VCC but above ~0.2 V, the device remains fully functional; IOFF does not engage during brown-out conditions.

What is the maximum capacitive load the 74AUP1T87GWH can drive while maintaining timing specs?

The device is characterized up to 30 pF load capacitance, with propagation delay specified as 1.3–11.9 ns across VCC, VI, and temperature. Driving >30 pF will increase tpd nonlinearly and may violate setup/hold margins; for loads beyond 30 pF, external buffering or slew-rate limiting is recommended per Nexperia Application Note AN10862.

Is the 74AUP1T87GWH pin-compatible with the 74AUP1T87GW variant?

Yes. Both 74AUP1T87GWH and 74AUP1T87GW use the identical SOT353-1 (TSSOP5) package with identical pinout (A-B-GND-Y-VCC), marking code "5D", and mechanical dimensions. The "H" suffix denotes tape-and-reel packaging per AEC-Q200-compliant handling - electrically and physically interchangeable.
