SN74AUC1G125YZTR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUC1G125YZTR is a single bus buffer gate with a 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. It provides ±8-mA output drive at 1.8 V with a maximum propagation delay of 2.5 ns at 1.8 V under a 30 pF load. The component utilizes the NanoFree DSBGA package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific YZP (DSBGA, 5) package configuration matches the design footprint requirements. Confirm that the operating temperature range of -40°C to +85°C aligns with the system environment. Ensure input pins are terminated properly to prevent floating states during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when low voltage operation between 0.8 V and 2.7 V is required. It is suitable for designs needing over-voltage tolerant inputs up to 3.6 V. Consider its small form factor and low power consumption for space-constrained portable electronics.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments AUC logic family, which is specifically engineered for speed and low power consumption. The AUC series supports sub-1-V little logic operations and is designed to maintain signal integrity while minimizing switching noise in high-frequency digital circuits.

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 handling for unused pins?

Unused inputs must not be left floating; they should be tied to VCC or GND to ensure proper device operation and prevent undefined operational states.
