Diodes Incorporated 74AUP1G98FZ4-7

Overview

74AUP1G98FZ4-7 from Diodes Incorporated is a single 3-input configurable multiple-function logic gate in X2-DFN1410-6 package, supporting MUX, AND, OR, NAND, NOR, inverter, and buffer functions via input pattern selection. It operates from 0.8V to 3.6V, delivers ±4mA output drive at 3.0V, features Schmitt-trigger inputs (950mV hysteresis @ 3.0V), and supports IOFF for partial power-down isolation. It is used in battery-powered voltage-level shifting and low-power logic interface circuits.

For engineers reviewing the 74AUP1G98FZ4-7 datasheet, 74AUP1G98FZ4-7 pinout, 74AUP1G98FZ4-7 application, or 74AUP1G98FZ4-7 equivalent, key selection considerations include its ultra-low static current (<0.9µA), 3.0V-compatible 3.6V-tolerant inputs, configurable logic mapping without external components, and DFN1410 footprint for space-constrained portable designs.

Technical Context

This device implements a programmable 3-input combinational logic cell where all eight input combinations map deterministically to high/low output states per the function table. Its Schmitt-trigger inputs provide noise immunity with hysteresis ranging from 0.07V (0.8V VCC) to 1.31V (3.0V VCC), enabling robust operation with slow-rising signals.

The IOFF circuit actively disables the output during power-down, blocking back-current flow when VCC = 0V while inputs or outputs remain biased-critical for mixed-voltage system hot-swap and power-gating integrity. Input tolerance up to 3.6V allows interfacing with higher-voltage domains without level shifters.

FAQ

Can 74AUP1G98FZ4-7 operate with VCC = 0.8V while accepting 3.3V input signals?

Yes. Its inputs are specified 3.6V-tolerant across the full VCC range (0.8V–3.6V), meaning a 3.3V signal applied to A, B, or C will not damage the device nor violate absolute maximum ratings-even when VCC is at minimum 0.8V. This enables true level-shifting without external components.

What happens to the output during power-down when VCC = 0V?

When VCC drops to 0V, the internal IOFF circuit activates, forcing the Y output into a high-impedance state with leakage ≤±0.6µA over –40°C to +125°C. This prevents reverse current flow from other powered rails through the output, protecting downstream circuitry during partial power-down sequences.

How is logic function selected-via programming or hardware wiring?

Function selection is purely hardware-based: the user connects A, B, and C inputs to VCC or GND to encode one of eight 3-bit patterns (e.g., CBA = 000 → NAND; 001 → NOR). No configuration register, clock, or firmware is involved-function is static and determined solely by DC biasing of the three inputs.

Does the X2-DFN1410-6 package require thermal vias for normal operation?

No. With θJA = 430°C/W and max junction temperature rated to +150°C, the device dissipates <10µW under typical logic switching conditions. Thermal vias are unnecessary for reliability; however, a 1.5mm² exposed pad soldered to a solid ground plane improves mechanical attachment and slightly reduces thermal resistance.
