Nexperia USA Inc. 74AUP1T00GX,125

Overview

74AUP1T00GX,125 from Nexperia is a single 2-input NAND gate IC with integrated voltage-level translation, designed for low-power logic interfacing between 1.8 V CMOS 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 - enabling use in battery-powered IoT sensor nodes and portable MCU peripherals.

For engineers reviewing the 74AUP1T00GX,125 datasheet, 74AUP1T00GX,125 pinout, 74AUP1T00GX,125 application, or 74AUP1T00GX,125 equivalent, this device is selected for ultra-low static power, rail-to-rail input tolerance (up to 3.6 V), guaranteed operation down to -40 °C/+125 °C, and compatibility with space-constrained X2SON5 packaging.

Technical Context

The 74AUP1T00GX implements a single 2-input NAND function with Schmitt-trigger inputs that provide hysteresis (0.10–0.60 V) across its full 2.3 V–3.6 V supply range, enabling robust operation with slow-rising signals. Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V.

It accepts 1.8 V logic inputs while operating from 2.5 V or 3.3 V supplies, making it suitable for bidirectional level shifting in mixed-voltage systems. Propagation delay ranges from 1.0 ns (VCC = 3.6 V, CL = 5 pF) to 11.9 ns (VCC = 2.3 V, CL = 30 pF), with dynamic power dissipation governed by CPD = 4–5 pF.

FAQ

Does the 74AUP1T00GX,125 support true bidirectional level shifting?

No - it is unidirectional: inputs accept 0 V–3.6 V signals, but the output swings only between GND and VCC (2.3 V–3.6 V). It translates low-voltage inputs to higher-voltage outputs, not vice versa. For bidirectional translation, a dedicated bus switch or dual-supply translator is required.

What is the maximum capacitive load the 74AUP1T00GX,125 can drive reliably?

The device is characterized up to 30 pF load capacitance, with propagation delay increasing from 1.0 ns (5 pF) to 11.9 ns (30 pF) at worst-case VCC and temperature. Driving >30 pF may cause excessive delay or marginal rise/fall times; external buffering is recommended beyond this limit.

Can Pin 3 (GND) be left floating if the thermal pad is soldered to a ground plane?

No - Pin 3 is the functional ground terminal and must be electrically connected to the system GND net. The exposed thermal pad in X2SON5 is internally connected to GND and serves as both thermal and electrical ground; omitting the Pin 3 connection creates an open ground path and will cause functional failure.

Is the 74AUP1T00GX,125 qualified for automotive applications per AEC-Q100?

No - while specified from -40 °C to +125 °C, this variant is not AEC-Q100 qualified. Nexperia offers the automotive-grade 74AUP1T00GW-Q100 (TSSOP5) for automotive applications; the GX variant is intended for industrial and consumer use where AEC-Q100 is not mandated.
