CY74FCT163543CPAC

Overview

The CY74FCT163543CPAC is a registered bus transceiver from the FCT series, manufactured by Cypress Semiconductor Corp. It features two independent functions, each handling eight bits of data with true output polarity. The device utilizes CMOS technology and is housed in a 56-pin TSSOP package with a shrink pitch. It supports bidirectional data flow with three-state outputs and includes independent output enable controls for each direction. The component operates within a temperature range of -40°C to 85°C.

Feature Summary

• Provides registered bidirectional data transfer capabilities between two ports.
• Features independent output enable control for each data direction.
• Delivers high-speed performance suitable for demanding system applications.

Applications

• High-performance computing systems requiring reliable data buffering.
• Clock distribution networks utilizing registered interfaces.
• Complex digital logic circuits needing isolated bidirectional pathways.

Procurement Notes

Verify the specific suffix against official Cypress documentation to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required operating temperature range and package dimensions for your design constraints. Cross-reference the manufacturer's latest datasheet to validate current production status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when designing systems that require registered bus transceivers with independent directional control. Consider the 56-pin TSSOP footprint for space-constrained layouts. Evaluate the propagation delay specifications against your system timing requirements to ensure signal integrity is maintained across the bidirectional data paths.

Part Context

This part belongs to the FCT (Fast CMOS Technology) family, known for speed and low power consumption. It serves as a bridge between different logic levels or buffers data in high-speed digital environments. The registered nature of the transceiver helps manage timing skew in complex parallel data buses.

Replacement Considerations

Consult official replacement guides for direct equivalents. Verify pin-to-pin compatibility and functional parity with alternative registered bus transceivers from the same manufacturer or compatible third-party sources.
