Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'NS' corresponds to the SOP-20 package variant when sourcing. Confirm the operating temperature range matches system requirements, as datasheet revisions may affect specifications. Ensure ESD precautions are followed during handling. Check for updated documentation or product change notifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-density 3-state memory address drivers or clock drivers. It is suitable for bus-oriented receivers and transmitters where signal integrity and drive strength are critical. Consider thermal resistance values if operating near maximum temperature limits. Verify compatibility with system logic levels across the full voltage range.
