SN74AUC1G125YEPR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G125YEPR is a single bus buffer gate with 3-state output from the AUC logic family, optimized for 1.65-V to 1.95-V operation within a wide supply range of 0.8 V to 2.7 V. It features over-voltage tolerant I/Os supporting up to 3.6 V independent of VCC and an Ioff feature for partial power down mode. The device provides ±8-mA output drive at 1.8 V with a maximum propagation delay of 2.5 ns at 30 pF load. It operates between -40°C and +85°C in a DSBGA-5 package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Single line driver with 3-state output controlled by active-low OE input
• Over-voltage tolerant I/Os support up to 3.6 V independent of VCC
• Ioff circuitry disables outputs during partial power down to prevent back drive current
• ULTTL output structure optimizes signal integrity on transmission lines without external termination

Buffers, Drivers, Receivers, Transceivers Applications

• Redrive digital signals
• Enable or disable a digital signal
• Drive transmission lines with logic

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'YEPR' against the manufacturer's official orderable addendum to confirm package type and availability status. Ensure compatibility with system voltage requirements and thermal constraints before procurement. Confirm RoHS compliance and lead finish specifications match design needs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for high-speed applications requiring low power consumption and optimal signal integrity. It is suitable for driving controlled impedance transmission lines directly. Verify that the operating voltage falls within the 0.8 V to 2.7 V range and that the output current limits are not exceeded.
