Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PACT' against official Texas Instruments documentation to confirm the exact tape-and-reel quantity and packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the 48-pin TSSOP footprint matches your PCB design constraints. Validate the lead time and availability status directly with authorized distributors as inventory levels fluctuate.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-channel buffer with three-state capability is required for 5V CMOS logic systems. It is suitable for designs needing reduced ground bounce and controlled edge rates. Consider the TSSOP-48 package size relative to available board space. Compare performance metrics such as propagation delay and output drive strength against alternative FCT series devices if tighter timing or higher current specifications are necessary.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the CY74FCT16244T family of 16-bit buffers and line drivers. The family includes variants with different speed grades and packaging options, such as the AT and CT speed bins. These devices are designed for high-density applications requiring small form factors like SSOP and TSSOP packages. The FCT technology combines CMOS density with Schottky TTL speed characteristics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives within the same FCT family, such as other CY74FCT16244 variants with different suffixes. Verify that any substitute maintains the 4.5V to 5.5V operating voltage and 16-bit width. Ensure the replacement offers equivalent three-state output functionality and similar propagation delay characteristics.
