SN74AUC1G125YZPR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G125YZPR is a single bus buffer gate with a 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 YZPR corresponds to the DSBGA-5 package configuration required for your design. Confirm that the component status remains active production before finalizing procurement plans. Ensure compatibility with the specified operating temperature range and thermal requirements for the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single non-inverting buffer with 3-state control is needed for low-voltage applications. It is suitable for systems requiring over-voltage tolerant inputs and outputs. Consider the DSBGA-5 package size constraints and the need for controlled impedance transmission lines for optimal signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AUC1G series, which is part of Texas Instruments' AUC logic family designed for speed and low power consumption. The AUC family is specifically optimized for operation between 1.65-V and 1.95-V VCC, providing excellent signal integrity without external termination for moderate length transmission lines.

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.

What is the purpose of the OE input?

The output-enable (OE) input controls the 3-state output. The output is disabled when OE is high and enabled when OE is low.
