Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SOIC-24 package and tape-and-reel orientation before procurement. Confirm that the required operating voltage aligns with the 4.5 V to 5.5 V specification. Ensure thermal management meets the -40°C to +85°C operational requirements for the intended environment. Cross-reference the datasheet for exact pinout configurations to prevent installation errors.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed asynchronous bus transfer is required with robust drive strength. The ABTH series offers faster performance compared to standard LS or HC families. Consider the SOIC-24 package constraints for PCB layout. Verify that the system voltage remains strictly within the 4.5 V to 5.5 V limits to ensure reliable operation and prevent device damage.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ABTH25245 family of octal bus transceivers. It shares functional similarities with other ABT-series devices but is optimized for specific voltage and speed requirements.
