Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'RE4' against the ordered part number, as it indicates lead-free status and tape-and-reel packaging which may differ from the base 'DW' designation. Confirm RoHS compliance requirements match the manufacturing revision. Ensure the SOIC-20 footprint matches the target PCB layout dimensions precisely before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed performance and significant drive strength are required compared to standard LS or ALS families. The AS series offers superior speed characteristics while maintaining compatibility with standard logic interfaces. Evaluate thermal dissipation needs due to higher output currents compared to lower-power alternatives.
