Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CT against the manufacturer's current datasheet to confirm pinout compatibility and electrical characteristics. Ensure the SSOP-20 package dimensions match the target PCB footprint. Confirm RoHS compliance status and moisture sensitivity level requirements for the assembly process. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal bidirectional interface is required for 5V logic systems. Compare drive strength and propagation delay specifications against alternative FCT series devices if higher speed or different packaging is needed. Consider the 20-pin SSOP form factor for space-constrained designs requiring through-hole or standard SMT reflow processes.

Buffers, Drivers, Receivers, Transceivers Part Context
