SN74AUP1G125DCKR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUP1G125DCKR is a low-power single bus buffer gate with a 3-state output, manufactured by Texas Instruments. It operates within a supply voltage range of 0.8 V to 3.6 V and supports an operating temperature from -40°C to +85°C. The device features balanced high-drive CMOS push-pull outputs capable of sourcing and sinking currents up to 4 mA at 3 V. It includes input-disable functionality allowing floating inputs and Ioff circuitry for partial-power-down mode operation. The package is SC-70 (5), measuring 2.00 mm x 1.25 mm.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix DCKR corresponds to the SC-70 package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the active-low output-enable pin configuration matches the system control logic design before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring minimal power consumption in portable electronics. The wide operating voltage range accommodates various supply rails. Verify that the load capacitance does not exceed limits that would degrade propagation delay beyond system timing requirements. Consider the thermal resistance characteristics if multiple devices are placed closely on the PCB.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AUP1G series, which represents Texas Instruments' solution for low-power logic in portable applications. The AUP family is designed to extend battery life through reduced static and dynamic power usage while maintaining signal integrity. This specific buffer gate provides non-inverting logic with controlled output enable capabilities.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct substitutes within the same AUP family or other low-power logic families from Texas Instruments. Verify pin compatibility and electrical characteristics such as propagation delay and output drive strength before substituting.
