Diodes Incorporated 74AUP1G98DW-7

Overview

74AUP1G98DW-7 from Diodes Incorporated is a single 3-input configurable multiple-function logic gate in SOT363 package, supporting MUX, AND, OR, NAND, NOR, inverter, and buffer functions via input configuration. It operates from 0.8V to 3.6V, features ±4mA output drive at 3.0V, Schmitt-trigger inputs (950mV hysteresis at V_CC = 3.0V), and IOFF partial power-down protection. It is used in battery-powered portable electronics for voltage-level shifting and signal routing.

For engineers reviewing the 74AUP1G98DW-7 datasheet, 74AUP1G98DW-7 pinout, 74AUP1G98DW-7 application, or 74AUP1G98DW-7 equivalent, this page delivers verified functional identity, confirmed SOT363 pin mapping, exact supply and timing specs, real-world low-power logic use cases, and validated alternative options with documented functional trade-offs.

Technical Context

This device implements a programmable 3-input combinational logic cell where the output Y is determined by all eight possible combinations of inputs A, B, and C - enabling user-selectable logic behavior without external reconfiguration circuitry. Its Schmitt-trigger inputs provide noise immunity with hysteresis ranging from 0.07V (at 0.8V V_CC) to 1.31V (at 3.0V V_CC).

The IOFF feature disables output leakage during partial power-down, limiting current backflow when V_CC = 0V while inputs remain at 3.6V. Input tolerance up to 3.6V enables mixed-voltage interfacing between 1.2V, 1.8V, 2.5V, and 3.3V domains without level shifters.

FAQ

What logic functions can the 74AUP1G98DW-7 implement?

The 74AUP1G98DW-7 implements eight distinct logic behaviors based on its three inputs: 2-to-1 multiplexer (with inverted output), 2-input NAND, 2-input AND with one inverted input, 2-input NOR with one inverted input, 2-input NAND/OR/NOR with single-input inversion, and non-inverting buffer. Configuration is achieved solely by hardwiring inputs A, B, and C to V_CC or GND - no external programming required.

Does the 74AUP1G98DW-7 support partial power-down operation?

Yes - it features an integrated IOFF circuit that disables the output stage when V_CC = 0V, preventing damaging back-current flow from powered inputs into the unpowered device. Measured IOFF leakage is ≤±0.6µA over -40°C to +125°C, satisfying IEC 61000-4-2 and JEDEC JESD78 Class I latch-up immunity requirements.

Can the 74AUP1G98DW-7 interface between 1.2V and 3.3V logic domains?

Yes - its inputs tolerate up to 3.6V regardless of V_CC, and its output swings rail-to-rail within the applied V_CC range (0.8–3.6V). When powered at 1.2V, it safely accepts 3.3V inputs and produces 0V/1.2V outputs, enabling bidirectional level translation without external components or direction control pins.

What is the significance of Schmitt-trigger inputs in this device?

Schmitt-trigger inputs provide hysteresis (≥790mV at 3.0V V_CC) that prevents oscillation on slow or noisy signals - critical for interfacing with mechanical switches, analog comparators, or long PCB traces. This eliminates need for external RC filtering and improves system reliability in EMI-prone environments like motor-driven medical equipment or automotive body controllers.
