74AUP1G98FHX

Overview

The Fairchild Semiconductor 74AUP1G98FHX is a single configurable multiple-function gate belonging to the 74AUP logic family. It features three inputs and one output housed in an SC-70-6 package. The device operates within a supply voltage range of 0.8 V to 3.6 V, ensuring low static power consumption across the entire voltage spectrum. It includes Schmitt trigger inputs for noise immunity and I_OFF circuitry to prevent backflow current during partial power-down states.

Feature Summary

• Configurable logic functions including MUX, AND, OR, NAND, NOR, inverter, and buffer via 3-bit input patterns
• Schmitt trigger inputs provide high noise immunity and jitter-free signal transformation
• I_OFF circuitry disables outputs to prevent damaging backflow current when powered down

Applications

• Low-power portable electronic devices requiring minimal static current
• Mixed-voltage systems utilizing 1.8 V and 3.3 V logic levels
• Partial power-down applications requiring isolation of powered-down sections

Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or its successor entity, as corporate acquisitions may affect branding on official datasheets. Confirm the specific suffix FHX corresponds to the SC-70-6 package variant. Ensure compliance with RoHS directives and check for end-of-life status prior to final procurement decisions.

Selection Notes

Select this component for designs prioritizing ultra-low power consumption and flexible logic configuration in a compact footprint. The wide operating voltage range supports various digital interfaces. Verify that the required logic functions align with the available 3-bit input configurations and that the package size fits the PCB layout constraints.

Part Context

This part belongs to the 74AUP series, designed for advanced ultra-low power applications. It serves as a versatile logic solution for battery-operated equipment where space and energy efficiency are critical. The configurable nature reduces bill-of-materials complexity by replacing multiple fixed-function gates with a single adaptable component.

Replacement Considerations

Cross-reference with Nexperia 74AUP1G98 variants for equivalent functionality. Verify pinout compatibility and electrical specifications against Diodes Incorporated equivalents before substitution.
