SN74AUC1G125DBVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G125DBVR is a single bus buffer gate with 3-state output from the 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. It is housed in a SOT-23-5 package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DBVR' corresponds to the SOT-23-5 package and tape-and-reel carrier configuration. Confirm that the component meets RoHS compliance standards and matches the manufacturer's current production status before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring ultra-low voltage operation and high-speed signal buffering. Ensure the design accommodates the 0.8-V to 2.7-V supply range and utilizes the Ioff feature if partial power down functionality is required for system power management.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments SN74AUC1G125 series, which is part of the AUC logic family designed for speed and optimized for sub-1-V little logic devices. The series includes variants available in SOT-23, SC70, and NanoFree DSBGA packages to suit different footprint constraints.

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 states.

What is the input transition rate requirement?

Input signals must transition quickly; specifically, the rate should be faster than 10 ns/V when operating between 1.65 V and 1.95 V to prevent excessive power consumption.
