Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (TSSOP48/SOT362-1) matches the design footprint. Confirm that the operating voltage range aligns with the system's power rails. Ensure thermal management meets the total power dissipation limits specified in the datasheet. Check for compliance with relevant environmental directives such as RoHS if required by the target market.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when 16-bit buffering with integrated termination is required. The MULTIBYTE™ architecture simplifies PCB layout compared to discrete solutions. Consider the bus hold feature if unused inputs must be stabilized without external resistors. Verify ESD protection requirements against HBM and CDM standards for the application environment.
