SN74HC125ANS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC125ANS is a quad bus buffer manufactured by Texas Instruments, belonging to the HC logic series. It features four non-inverting channels with three-state outputs housed in a 14-SOIC package. The device operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation. Key electrical parameters include a high-level output current of -7.8 mA and a low-level output current of 7.8 mA. Static current is specified at 8 uA, while operating supply current reaches 160 uA. Propagation delays vary from 150 ns at 2 V to 25 ns at 6 V. The component functions reliably across an extended temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ANS' against the manufacturer's official documentation to confirm package dimensions and tape/reel specifications. Ensure compatibility with existing PCB footprints and soldering profiles. Confirm RoHS compliance status through the latest datasheet revision. Check for any recent product lifecycle notices or obsolescence warnings directly from Texas Instruments before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring isolated bus buffers with moderate drive capability. The HC series offers compatibility with standard TTL levels while maintaining low power consumption. Consider the propagation delay variations based on the actual supply voltage used in the target application. Evaluate thermal requirements to ensure operation remains within the specified -40°C to +85°C range under all expected load conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HC125 family of quad bus buffers. It shares functional similarities with other variants like the SN74HC125D but differs in packaging and specific manufacturing revisions. The HC series represents a high-speed CMOS alternative to older logic families, offering improved switching speeds and noise immunity. It is commonly used in digital systems where multiple signals need simultaneous buffering and direction control on shared data lines.
