SN74LV125ATDBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV125ATDBR is a quad bus buffer and line driver from Texas Instruments, belonging to the LV logic series. It features four non-inverting inputs with three-state outputs in a 14-pin SSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a low-level output current of 16 mA and a high-level output current of -16 mA. Propagation delay is specified at 7.5 ns when operating at 5 V. The component supports surface-mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent non-inverting buffer channels for signal conditioning
• Features three-state outputs to facilitate bus-oriented connections
• Designed for operation with standard 5 V CMOS logic families

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented systems requiring signal buffering
• Clock distribution networks
• Memory address and data bus drivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'A' and 'DBR' against the manufacturer's official documentation to confirm the exact pinout, package dimensions, and tape-and-reel specifications. Ensure that the 5 V supply requirement aligns with the target system design, as this device does not support lower voltage levels typical of other logic families.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 5 V supply is available and four buffered channels are required. Compare propagation delay and drive strength against alternative logic families if higher speed or different voltage compatibility is needed. Confirm that the SSOP-14 package fits the PCB layout constraints and thermal requirements of the application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV125 family of quad bus buffers. It shares functional similarities with other devices in the LV series but is distinct due to its specific 5 V operating voltage range and SSOP packaging. It serves as a standard interface component for connecting microprocessors to peripheral devices in 5 V logic environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct substitutes such as the SN74LV125ADBR or SN74LV125APWR, ensuring identical pinouts and electrical characteristics. Verify that any replacement maintains the same 5 V supply voltage and three-state output functionality.
