SN74HC125ADBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC125ADBR is a quad bus buffer gate manufactured by Texas Instruments, belonging to the HC logic family. It features four non-inverting buffers with three-state outputs housed in a 14-pin TSSOP 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 static current of 8 µA, high-level output current of -7.8 mA, and low-level output current of 7.8 mA. Propagation delay varies based on voltage: 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 'ADBR' corresponds to the TSSOP-14 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the procurement channel provides traceable origin to avoid counterfeit components. Cross-reference the ordering part number against the latest Texas Instruments product selection guide to confirm availability and manufacturing status.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring CMOS compatibility with standard TTL input levels. The HC series offers higher speed than legacy LS variants while maintaining low power consumption. Consider the propagation delay specifications relative to system clock speeds. The three-state capability is essential for multiplexed data lines. Verify that the 14-pin TSSOP footprint matches the PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the SN74HC125 family of quadruple bus buffer gates. It shares functional similarities with other HC series devices but is distinguished by its specific package type and three-state output configuration. The HC technology combines the benefits of high-speed CMOS operation with low power dissipation, making it suitable for battery-powered and general-purpose digital applications.
