Overview
The CY74FCT163543CPACT is a 16-bit registered bus transceiver from the FCT logic series, manufactured by Texas Instruments. It features two independent functions with true outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a TSSOP-56 package and supports surface mount installation. Key electrical parameters include a propagation delay of 8 ns at 5 V, low-level output current of 32 mA, and high-level output current of -32 mA. It operates between -40°C and +85°C, with a maximum static current of 5 uA.
Feature Summary
- Provides registered data storage for bus applications
- Features independent output enable control for each direction
- Delivers three-state outputs for efficient bus sharing
Applications
- High-speed data bus interfaces
- Memory buffer circuits
- I/O port expansion systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Ensure proper handling procedures are followed due to moisture sensitivity level requirements. Check for obsolescence notices regarding production lifecycle status before finalizing procurement plans.
Selection Notes
Select this component for designs requiring 16-bit bidirectional data transfer with internal latching capabilities. The FCT series offers compatibility with standard CMOS logic families. Consider the TSSOP-56 package constraints for PCB layout. Evaluate thermal performance within the specified operating temperature range during system integration.
Part Context
This part belongs to the CY74FCT163543T family of registered bus transceivers. It serves as a bridge between microprocessors and peripheral devices. The device integrates clocked registration to synchronize data movement across buses. It is designed for high-density digital systems requiring reliable data retention.
Replacement Considerations
Check for pin-compatible alternatives within the same FCT series. Verify functional equivalence regarding propagation delay and drive strength. Ensure package dimensions match existing footprints. Consult official substitution guides for validated cross-references.
