Nexperia USA Inc. 74AUP1G98GXZ

Overview

74AUP1G98GX from Nexperia is a low-power configurable multiple-function logic gate with Schmitt-trigger inputs, capable of implementing MUX, AND, OR, NAND, NOR, inverter, or buffer functions via its 3-bit input configuration (A/B/C). It operates across 0.8 V to 3.6 V supply, delivers ≤1.4 μA max ICC at −40 °C to +125 °C, and features IOFF partial power-down protection. It is used in battery-powered sensor interfaces and voltage-level-agnostic control logic where function reconfiguration without hardware change is required.

For engineers reviewing the 74AUP1G98GX datasheet, 74AUP1G98GX pinout, 74AUP1G98GX application, or 74AUP1G98GX equivalent, key selection criteria include its ultra-low static current, Schmitt-trigger noise immunity, IOFF-enabled system-level power sequencing, and compatibility with mixed-voltage I/O domains down to 0.8 V.

Technical Context

The device implements a single-output, three-input configurable logic cell using CMOS technology with Schmitt-trigger inputs for robust noise rejection. Its function is determined by the logic state of inputs A, B, and C per the documented truth table - no external programming interface or non-volatile memory is involved.

It supports full I/O overvoltage tolerance up to 3.6 V independent of VCC, and IOFF circuitry actively disables outputs during VCC = 0 V, preventing backflow current in partial power-down systems. All inputs may be hard-wired to VCC or GND for fixed-function implementation.

FAQ

Can 74AUP1G98GX be used with VCC = 1.2 V while interfacing to a 3.3 V microcontroller GPIO?

Yes. Its inputs tolerate up to 3.6 V regardless of VCC, so the 3.3 V GPIO can safely drive any input pin (A/B/C/Y) without level shifting. The output Y will swing rail-to-rail between 0 V and 1.2 V, requiring a level translator if the microcontroller needs to read the output as a valid HIGH.

How is the logic function selected - is configuration persistent after power cycle?

Function selection is purely combinational and determined in real time by the logic states applied to pins A, B, and C. No configuration memory or initialization sequence is required. The function changes immediately when input states change, and no persistence exists across power cycles.

What is the purpose of the thermal pad on the SOT1255-2 package?

The exposed thermal pad on the bottom of the X2SON6 (SOT1255-2) package improves heat dissipation but is not electrically connected. It must be soldered to a PCB thermal pad for optimal thermal performance, though electrical isolation from all signals and power planes is mandatory.

Does the IOFF feature protect against backfeed when only VCC is 0 V but GND remains connected?

Yes. IOFF activates when VCC = 0 V, regardless of GND state. With GND connected and VCC floating or grounded, the output Y is actively disabled, limiting leakage to ±0.75 μA maximum - sufficient to prevent damaging backfeed into powered downstream circuits.
