SN74AUC1G125YZAR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G125YZAR 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. It is housed in a DSBGA-5 package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'YZAR' against the manufacturer's current orderable addendum to confirm availability and exact packaging details. Confirm that the DSBGA-5 package dimensions match the design footprint requirements. Ensure compliance with RoHS and lead-free specifications as indicated in the product documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel non-inverting buffer with 3-state control is required for low-voltage systems. It is suitable for designs needing over-voltage tolerant inputs and outputs while operating at supply voltages as low as 0.8 V. Consider the NanoFree™ package size if board space is constrained.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the OE input?

The OE (Output Enable) input controls the state of the output. When OE is high, the output is disabled (high impedance). When OE is low, the output follows the input A.

How does the Ioff feature work?

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