CY74FCT2652ATQCT

Overview

The CY74FCT2652ATQCT is an octal registered bus transceiver from the FCT logic series, manufactured by Cypress Semiconductor Corp. It features a QSOP-24 package and operates with a supply voltage range of 4.75 V to 5.25 V. The device provides bidirectional data transfer with registered outputs, supporting TTL input and output levels. It includes independent direction control and offers three-state outputs for effective bus management in high-speed digital systems.

Feature Summary

• Octal registered bus transceiver architecture providing data storage and bidirectional transfer capabilities
• Independent direction control pins allowing flexible data flow management between ports
• Three-state outputs designed to minimize loading effects on system buses during inactive states

Applications

• High-speed memory buffer applications requiring data registration
• Bidirectional bus architectures in embedded systems
• I/O port expansion circuits in industrial control environments

Procurement Notes

Verify the manufacturer designation as Cypress Semiconductor Corp or Texas Instruments depending on the specific production lot, as corporate transitions may affect labeling. Confirm the QSOP-24 package type and ensure compatibility with standard surface mount assembly processes. Check datasheet specifications for humidity sensitivity handling requirements prior to installation.

Selection Notes

Select this component when an octal width with internal latching is required for bus isolation. The FCT series offers faster switching speeds compared to standard 74F logic while maintaining CMOS power efficiency. Ensure the design accommodates the 5V operating voltage and utilizes the independent direction controls for optimal bus arbitration.

Part Context

This part belongs to the CY74FCT family of fast CMOS logic devices originally developed by Cypress Semiconductor. These components are engineered for high-performance digital applications requiring low propagation delay and strong drive capability. The registered variant distinguishes itself by incorporating D-type flip-flops at the output stage to stabilize bus signals.

Replacement Considerations

Direct substitutes include the CY74FCT2652ATQC for leaded packaging variants. Other compatible options within the same functional family may include non-registered counterparts like the CY74FCT245 if latching is not required, provided pinouts and electrical characteristics align with the design constraints.
