Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DG4' or 'RG4' against the manufacturer's official ordering information to confirm RoHS compliance status and lead time requirements. Ensure the SSOP-20 package dimensions match the target PCB footprint. Confirm that the voltage levels of the driving source are compatible with the 1.65 V to 3.6 V input range to prevent damage or undefined states.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require buffering between different voltage domains, such as interfacing 3.3 V logic with 1.8 V or 2.5 V devices. The LVC series offers lower power consumption compared to older CMOS families. Consider the propagation delay specifications if timing constraints are critical for the application. Verify thermal performance under maximum load conditions given the wide operating temperature range.
