Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'TPACT' against official Cypress or Infineon documentation to confirm the tape-and-reel packaging and temperature grade. Ensure compatibility with existing PCB footprints for the TSSOP-56 package. Confirm RoHS compliance status as indicated in the most recent datasheet revision, noting that some legacy listings may indicate non-compliance.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit registered transceiver with independent control is required. It is suitable for designs needing high-speed data buffering with built-in registration. Compare propagation delay specifications against system timing requirements. Ensure the power supply voltage aligns with the 4.5V to 5.5V operational range specified for the FCT family.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the FCT (Fast CMOS Technology) series, designed for high-speed digital applications. It serves as a bridge between microprocessors and peripheral devices, offering data latching capabilities. The registered nature allows for synchronized data transfer, reducing setup time constraints on the receiving end compared to unregistered transceivers.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-to-pin replacements such as the CY74FCT162646CTPVC or CY74FCT162646TPVCT, ensuring package differences (TSSOP vs SSOP) are accounted for. Verify functional equivalence regarding the registered bus transceiver architecture and electrical characteristics before substitution.
