SN74HC125APWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC125APWR is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It belongs to the HC logic series and features non-inverting polarity. The device operates within a supply voltage range of 2V to 6V and supports four input lines and four output lines. It is housed in a TSSOP-14 surface-mount package suitable for SMD/SMT installation. The component functions as a buffer and line driver, providing high-level output current of -7.8mA and low-level output current of 7.8mA. It is RoHS compliant and designed for general-purpose logic applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent non-inverting buffer channels with 3-state output capability for bus-oriented communication.
• Operates across a wide supply voltage range from 2V to 6V, ensuring compatibility with various digital systems.
• Features Schmitt-trigger inputs on select variants within the family to accept slow-rising signals, though standard HC inputs are specified for this part.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented systems requiring signal buffering and isolation.
• Clock distribution circuits where 3-state control is necessary.
• Memory address drivers and data bus transceivers.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official documentation to confirm if it denotes a specific tape-and-reel configuration or regional variant, as standard datasheets often list 'SN74HC125PWR'. Ensure the ordering part number matches the exact package and reel specifications required for your assembly process. Cross-reference the RoHS status and moisture sensitivity level with the latest production change notices.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with 3-state outputs is required for HC-speed logic applications. It is suitable for designs needing operation between 2V and 6V. Compare propagation delay and output drive strength against other HC series buffers if higher speed or different packaging is needed. Ensure the TSSOP-14 footprint aligns with the PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the SN74HC125 family of quadruple bus buffer gates. It shares functional similarities with other members like the SN74HC125PWR but may differ in packaging details or manufacturing site codes indicated by the suffix. It serves as a fundamental building block for digital logic interfaces, enabling controlled signal transmission on shared buses.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include SN74HC125PWR and SN74HC125PWRE4. Verify pinout compatibility and electrical characteristics before substitution. Other compatible parts in the same family should be checked for identical package dimensions and thermal performance.
