Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'TNS' corresponds to the TSSOP-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the ordering part number matches the exact pin configuration and thermal requirements for your PCB layout design before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring bidirectional data flow with low power consumption. The LV series offers better speed than standard LVC while maintaining compatibility with lower voltage domains. Consider the TSSOP-20 package size constraints and ensure adequate thermal management for the operating environment. Verify input/output voltage levels match the connected system components.
