Procurement Notes

Verify the specific suffix 'CTPACT' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure compatibility with existing PCB footprints for the TSSOP-56 package. Confirm that the selected variant meets all required environmental and electrical specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring registered data latching combined with bidirectional bus driving capabilities. The dual 8-bit structure allows for flexible configuration of 16-bit wide data paths. Consider the propagation delay characteristics and drive strength requirements relative to the load capacitance of the connected bus lines to ensure signal integrity across the operating temperature range.

Part Context

This part belongs to the CY74FCT16952T family of registered bus transceivers. These devices are engineered for high-performance digital applications where data synchronization and bus isolation are critical. The FCT series combines the speed of Schottky TTL with the low power consumption of CMOS technology, making it suitable for demanding embedded and industrial environments.

Replacement Considerations

Consult official substitution guides for compatible alternatives within the same logic family or equivalent performance tiers. Verify pinout compatibility and electrical parameter alignment before replacing the component in existing designs.
