SN74HC125NS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC125NS 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-pin SOIC package. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40°C to +85°C. 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 propagation delay varies from 150 ns at 2 V to 25 ns at 6 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through the manufacturer's latest environmental files. Check for any product change notifications regarding pinout or electrical characteristics before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple buffered outputs with high-impedance states. Ensure the application voltage falls within the 2 V to 6 V range. Consider the propagation delay variations across different supply voltages when timing constraints are critical.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HC125 family of quad bus buffers. It is distinct from the SN74HC126 which uses active-high enables instead of active-low. The HC series offers speed comparable to LS TTL but with lower power dissipation. It serves as a standard interface solution for digital logic interfacing tasks.
