SN74AUC1G125YEAR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G125 is a single bus buffer gate with 3-state output from the Texas Instruments AUC logic family. It operates within a supply voltage range of 0.8 V to 2.7 V and is optimized for 1.65-V to 1.95-V operation. The device features over-voltage tolerant I/Os supporting up to 3.6 V independent of VCC, an Ioff feature for partial power down mode, and low power consumption with a maximum ICC of 10 µA. Latch-up performance exceeds 100 mA per JESD 78, Class II.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix (DBV, DCK, or YZP) matches the required footprint. Confirm RoHS compliance and lead finish details in the orderable addendum. Ensure design accounts for active-low OE functionality and proper termination of unused inputs to prevent floating states.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring ultra-low voltage operation and high speed. The AUC family provides excellent signal integrity for driving controlled impedance transmission lines without external termination. Consider thermal resistance values when designing for dense PCB layouts.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature function?

The Ioff circuitry disables all outputs when the supply pin is held at 0 V, preventing damaging current backflow through the device during partial power-down conditions.

What is the recommended input state for unused pins?

All unused inputs must be connected to a logic high or logic low voltage (VCC or GND) to prevent undefined operational states and excessive power consumption caused by floating inputs.
