SN74ALVC125D

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVC125D is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features independent line drivers. The device provides a maximum propagation delay of 2.8 ns at 3.3 V and supports ±24-mA output drive current at the same voltage. It is housed in a 14-pin SOIC (D) package and functions within an operating free-air temperature range of -40 °C to 85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific orderable part number matches the required package type, as the SN74ALVC125 family includes variants such as DR, NSR, PWR, and DGVR. Confirm the presence of the 'D' suffix indicates the standard SOIC tube packaging. Ensure compliance with RoHS standards and check for any specific material or lead finish requirements listed in the manufacturer's ordering information before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low-voltage logic interfacing between 1.65 V and 3.6 V domains. The SN74ALVC125D is suitable for applications demanding fast switching speeds and moderate drive strength. Consider the 14-pin SOIC package constraints regarding board space and thermal dissipation. Verify that input and output voltage levels remain within the recommended operating conditions to ensure proper functionality.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ALVC (Advanced Low-Voltage CMOS) logic family, which bridges the performance gap between older LVCMOS technologies and higher-speed alternatives. It is designed to replace legacy 5-V devices in modern low-power systems while maintaining compatibility with various logic families. The quadruple configuration allows for efficient management of multiple data lines within a single integrated circuit footprint.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements within the same family include SN74ALVC125DR, SN74ALVC125NSR, SN74ALVC125PWR, and SN74ALVC125DGVR. These variants offer identical electrical characteristics but differ in packaging formats such as tape-and-reel or different physical footprints like TSSOP or SOP.
