Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' against the manufacturer's current datasheet to confirm package dimensions and electrical characteristics match project requirements. Ensure the ordering part number corresponds to the correct tape-and-reel quantity or cut-tape availability as specified in the official documentation. Cross-reference the RoHS status and environmental compliance details directly with the latest TI publication before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver is required for bidirectional communication across varying voltage levels. The wide supply voltage range accommodates both 5-V and 3-V systems. Consider the TSSOP-48 package size for space-constrained designs. Verify that the maximum data rate and propagation delay meet the timing constraints of the target application interface.
