Procurement Notes

Verify the specific package variant and manufacturer revision when sourcing this component. Confirm that the ordering suffix matches the required pin configuration and thermal characteristics. Ensure compatibility with existing PCB footprints and soldering profiles. Cross-reference the datasheet version to validate electrical parameters against current design requirements before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring high-speed bidirectional data transfer with built-in storage capabilities. The FCT series offers CMOS performance with TTL-compatible inputs, simplifying interface design. Consider the 24-SOIC package constraints regarding board space and thermal dissipation. Evaluate the 5.5 ns propagation delay against system timing budgets to ensure signal integrity is maintained during operation.

Part Context

This part belongs to the CY74FCT2543T family of registered bus transceivers. It serves as a bridge between microprocessors and peripheral devices, providing temporary data storage at the bus interface. The integration of registration helps isolate bus fluctuations from the receiving end, enhancing system stability in complex digital environments.
