SN74AUP1G125DRLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUP1G125DRLR is a 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 a maximum propagation delay of 4.6 ns at 3.3 V, low static power consumption (ICC = 0.9 µA maximum), and low dynamic power consumption (Cpd = 4 pF typical). It includes input-disable functionality, Ioff support for partial-power-down modes, and over-voltage tolerant inputs.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the orderable addendum in the datasheet, as the DRL suffix corresponds to the SOT-5 package. Confirm that the OE pin is properly biased during power-up or power-down sequences using a pullup resistor to ensure the high-impedance state. Ensure input transition rates comply with the specified limits to prevent oscillations.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring minimal power usage in portable electronics. The wide operating voltage range accommodates various logic levels. Verify that the load capacitance requirements align with the switching characteristics tables provided in the datasheet. Consider the thermal resistance values 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' low-power AUP family designed for battery-operated portable applications. The series emphasizes reduced static and dynamic power consumption across the entire voltage range while maintaining excellent signal integrity and fast switching speeds compared to older logic families.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check the SN74AUP1G126DRLR for a similar buffer with different control logic polarity. Review the SN74AHC1G125DRLR for higher drive capability at slightly higher voltages. Consult the manufacturer's cross-reference tools for other NanoStar package options like DBV or DCK.
