SN74AUP1G125YZTR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUP1G125YZTR is a low-power single bus buffer gate with 3-state output from the Texas Instruments AUP logic family. It operates within a wide supply voltage range of 0.8 V to 3.6 V and supports mixed-mode signal operation via 3.6-V I/O tolerance. The device features an input-disable function allowing floating inputs, partial-power-down support through Ioff circuitry, and input hysteresis for improved noise immunity. Packaged in a 5-pin DSBGA (YZT) measuring 0.89 mm by 1.39 mm, it delivers a maximum propagation delay of 4.6 ns at 3.3 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the YZT suffix confirms the specific 5-pin DSBGA package configuration required for your layout. Confirm that the ordering suffix matches the exact reel or cut tape specifications needed for your assembly process. Ensure the component meets RoHS compliance standards applicable to your manufacturing region before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring low power consumption alongside high drive capability in compact spaces. The wide operating voltage range accommodates various power supply architectures. Consider the 3-state output for bus sharing applications and verify thermal management requirements based on the specific load capacitance and switching frequency of the target design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AUP1G series, representing Texas Instruments' solution for ultra-low power logic in portable electronics. The AUP family is engineered to extend battery life while maintaining signal integrity. The SN74AUP1G125 specifically provides non-inverting buffering with output enable control, distinguishing it from inverters or multi-gate buffers within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible alternatives include other packages of the SN74AUP1G125 such as DBV, DCK, or DPW. Cross-referencing with similar AUP family buffers requires verifying identical pinouts and electrical characteristics to ensure functional compatibility without redesigning the PCB footprint.
