• Provides three-state outputs to facilitate efficient bus sharing and system isolation.
• Ensures compatibility with TTL logic families through specified input and output voltage thresholds.

Applications

• High-speed data acquisition systems requiring buffered signal transmission
• Memory interface circuits utilizing registered data paths
• Industrial control networks needing isolated bidirectional communication channels

Procurement Notes

Verify the specific suffix CPVCT against the manufacturer's official datasheet to confirm the 56-SSOP package configuration and commercial grade temperature rating. Ensure that the ordering documentation explicitly references the CY74FCT163646 series specifications, as variations in suffixes may indicate different packaging or performance grades. Cross-reference the part number with the latest Texas Instruments product selection guide to validate current availability status and compliance with RoHS standards before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require 16-bit wide data buses with built-in latching functionality. The FCT logic family offers faster switching speeds compared to standard 74LS series devices while maintaining CMOS power efficiency. Consider the 56-pin SSOP footprint during PCB layout planning to ensure adequate clearance for thermal management and signal integrity. Verify that the system power supply remains stable within the 4.5 V to 5.5 V range to maintain optimal propagation delay characteristics and output drive strength.
