CY74FCT16646CTPVCT

Overview

The CY74FCT16646CTPVCT is a 16-bit registered bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features three-state outputs. The device utilizes the FCT logic series and includes TTL-compatible input levels with CMOS output levels. It is housed in a 56-pin SSOP package and supports surface mount installation. The component functions as a bidirectional data bus transceiver with integrated registers, allowing data on the A or B bus to be clocked into the registers for storage and controlled transmission.

Feature Summary

• Integrates 16-bit registered bus transceiver functionality with independent control capabilities
• Provides three-state outputs for effective bus line management and isolation
• Features TTL-compatible inputs ensuring compatibility with standard logic families
• Supports bidirectional data transfer between two distinct buses

Applications

• High-density memory mapping systems requiring registered data buffering
• Clock-driven bus architectures utilizing registered transceivers
• Bidirectional data gate implementations in industrial control environments

Procurement Notes

Verify the specific suffix 'CTPVCT' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the procurement source provides valid RoHS compliance certificates and confirms the component is from an authorized distribution channel to avoid counterfeit parts.

Selection Notes

Select this component when a 16-bit width is required for registered bus applications. Consider the 56-pin SSOP package constraints regarding PCB space and thermal dissipation. Verify that the system operating temperature range aligns with the specified -40°C to +85°C limits and that the 4.5V to 5.5V power supply is stable.

Part Context

This part belongs to the CY74FCT16646 family of registered bus transceivers. It serves as a high-speed interface solution for connecting microprocessors to peripheral devices or memory arrays. The registered nature of the transceiver helps mitigate timing issues in complex digital systems by synchronizing data transitions at the receiving end.

Replacement Considerations

Consult official substitution guides for compatible alternatives such as the 74FCT16646ATPVCG4. Verify pinout compatibility and electrical specifications before replacing the original component.
