SN74HC125APW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC125APW is a quadruple bus buffer gate manufactured by Texas Instruments, belonging to the HC logic series. It features four non-inverting channels with three-state outputs housed in a TSSOP-14 surface-mount package. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a high-level output current of -7.8 mA and a low-level output current of 7.8 mA. Propagation delay varies with voltage, specified as 150 ns at 2 V, 30 ns at 4.5 V, and 25 ns at 6 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'APW' against the manufacturer's latest documentation to confirm the exact tape-and-reel quantity and moisture sensitivity level. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the ordering information with official Texas Instruments catalogs to avoid obsolete or discontinued variants.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring quadruple bus buffers with three-state control. It is suitable for applications needing operation across a wide voltage range of 2 V to 6 V. Consider the TSSOP-14 package constraints for PCB layout. Verify that the propagation delay specifications meet the timing requirements of your specific digital interface.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HC125 family of quadruple bus buffers. It shares functional similarities with other HC series devices but is distinguished by its specific package type and pinout configuration. The family is designed for general-purpose digital logic applications requiring high noise immunity and low power dissipation typical of CMOS technology.
