Nexperia USA Inc. 74AUP1T87GX,125

Overview

74AUP1T87GX,125 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 inputs. It delivers ultra-low static current (≤1.5 μA), Schmitt-trigger inputs for noise immunity, and IOFF partial power-down protection. It is used in battery-powered IoT sensor interfaces requiring level-shifting between 1.8 V logic and 2.5/3.3 V domains.

For engineers reviewing the 74AUP1T87GX,125 datasheet, 74AUP1T87GX,125 pinout, 74AUP1T87GX,125 application, or 74AUP1T87GX,125 equivalent, key selection criteria include its 2.3–3.6 V supply range, 1.5 μA max ICC, IOFF-enabled power sequencing, Schmitt-trigger input hysteresis (≥0.15 V), and X2SON5 thermal-enhanced packaging for space-constrained PCBs.

Technical Context

This device implements a single 2-input EXCLUSIVE-NOR logic function with true voltage-level translation: inputs tolerate up to 3.6 V regardless of VCC, enabling interoperability between 1.8 V drivers and higher-VCC systems. Its Schmitt-trigger inputs provide ≥0.15 V hysteresis across -40 °C to +125 °C, ensuring robust switching despite slow-rising signals.

The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V, while input leakage remains ≤±0.75 μA. Propagation delay ranges from 1.3 ns (VCC = 3.6 V, VI = 3.6 V, CL = 5 pF) to 11.9 ns (VCC = 2.3 V, VI = 1.65 V, CL = 30 pF), supporting both high-speed and ultra-low-power operation.

FAQ

What is the maximum input voltage the 74AUP1T87GX,125 can safely accept?

The device accepts input voltages from -0.5 V to +4.6 V, with guaranteed operation up to 3.6 V regardless of VCC level. This enables direct connection to 1.8 V, 2.5 V, or 3.3 V drivers without external level-shifting components, provided input current remains within ±50 mA clamping limits per IEC 60134.

Does the 74AUP1T87GX,125 support true bidirectional level translation?

No-it performs unidirectional level translation only: inputs accept wide-voltage signals (up to 3.6 V), but the output swings between GND and VCC (2.3–3.6 V). It cannot translate from VCC-referenced logic back to lower-voltage domains; use dedicated bidirectional translators like TXB0104 for that function.

How does the IOFF feature behave during power sequencing?

When VCC drops below ~0.2 V, the IOFF circuit automatically disables the output driver, limiting leakage to ≤±0.75 μA. This prevents reverse current flow from powered downstream circuits into the unpowered gate, protecting both the 74AUP1T87GX,125 and connected ICs during staggered power-down sequences.

Can the 74AUP1T87GX,125 drive a 15 pF load at 3.3 V with <5 ns propagation delay?

Yes: at VCC = 3.3 V and VI = 3.0–3.6 V, the typical propagation delay into 15 pF is 4.0–5.7 ns, well within the <5 ns requirement. Measured values remain under 6.3 ns across -40 °C to +125 °C, satisfying timing-critical sensor interface designs.
