74AUP1G56FHX

Overview

The 74AUP1G56FHX is a configurable multi-function logic gate from the 74AUP series, manufactured by Fairchild Semiconductor (now onsemi). It implements majority logic functions within a single circuit. The device operates on a supply voltage range of 0.8V to 3.6V and features low power consumption suitable for portable applications. It utilizes a 6-UFDFN package, specifically 6-MicroPak2, designed for surface-mount assembly. The component supports an operating temperature range of -40°C to 85°C and provides single-ended output with drive capabilities of 4mA high and 4mA low.

Feature Summary

• Configurable multi-function logic capability allowing implementation of various gate types
• Low voltage operation supporting systems down to 0.8V
• Compact surface-mount packaging optimized for space-constrained designs

Applications

• Portable consumer electronics requiring low power logic
• Battery-operated devices utilizing sub-1V logic levels
• General purpose digital signal processing interfaces

Procurement Notes

Verify current availability status as distribution channels may vary between original Fairchild stock and onsemi inventory. Confirm package authenticity and RoHS compliance through official manufacturer declarations. Check for obsolescence notices or lifecycle changes that may affect long-term sourcing stability.

Selection Notes

Select this component when a single configurable gate is required for majority logic or alternative function mapping in low-voltage environments. Ensure the design accommodates the 0.8V minimum supply requirement. Verify that the 6-pin footprint matches the PCB layout constraints for the MicroPak2 package type.

Part Context

This part belongs to the 74AUP family of ultra-low-power CMOS logic devices. It serves as a versatile building block for complex logic implementations within minimal silicon area. The transition from Fairchild Semiconductor to onsemi represents the corporate restructuring following the merger, affecting branding but maintaining technical specifications.

Replacement Considerations

Public confirmed substitutes include 74AUP1G58FHX. Verify pinout compatibility and functional equivalence before integration into existing designs.
