Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the 'E4' designation aligns with environmental compliance requirements. Ensure the SOIC-20 package dimensions match the target PCB footprint. Cross-reference the LVTH series specifications against the design's power and speed constraints before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring robust drive strength with LVTTL compatibility. The LVTH series offers higher current capability compared to standard LV or HC families. Consider the 5.1 ns propagation delay for timing analysis. Verify that the 3.6 V maximum supply voltage suits the system power rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH2245 family of octal bus transceivers. It shares functional similarities with other ABT/LVTH devices but is distinct in its specific voltage and drive characteristics. The NSRE4 variant specifies the tube/reel packaging and environmental attributes within the broader Texas Instruments logic portfolio.
