SN74HC125DR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC125DR is a quad bus buffer and line driver manufactured by Texas Instruments. It belongs to the HC logic series and features four non-inverting channels with three-state outputs. The device operates within a supply voltage range of 2 V to 6 V. 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 power current reaches 160 uA. Propagation delay varies from 150 ns at 2 V to 25 ns at 6 V. It functions in temperatures from -40 C to +85 C and is housed in a 14-SOIC package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration intended for automated assembly processes. Confirm RoHS compliance status and ensure the component meets the required湿气敏感性等级 (MSL) for your specific reflow soldering profile. Check for any recent Product Change Notifications regarding manufacturing site or material updates.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require multiple buffered signals with high-impedance states on a shared bus. Ensure the operating voltage aligns with the 2 V to 6 V specification. Consider the propagation delay characteristics relative to your system clock speed. Verify that the SOIC-14 package dimensions fit your PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is a member of the SN74HC125 family of quad bus buffers. It shares functional similarities with other HC series logic devices but is distinguished by its specific three-state output capability and 14-pin SOIC packaging. It serves as a standard interface component in digital logic designs involving data buses.
