CY74FCT821BTSOCT

Overview

The CY74FCT821BTSOCT is a 10-bit bus interface flip-flop manufactured by Texas Instruments. It features 3-state outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device utilizes FCT logic series technology with CMOS construction. It is housed in a 24-pin SOIC package designed for surface mount installation. The component supports an operating temperature range from -40°C to +85°C. Key electrical specifications include a maximum low-level output current of 64 mA and a load capacitance rating of 50 pF. The part belongs to the CY74FCT821T series.

Feature Summary

• Provides 10-bit unidirectional data storage capability
• Features independent control for tri-state outputs
• Supports high-speed bus interface applications

Applications

• Bus interface systems requiring 10-bit data latching
• High-speed digital signal processing circuits
• Computer peripheral interface designs

Procurement Notes

Verify the specific suffix 'BT' against official manufacturer documentation to confirm tape and reel packaging configuration. Ensure the order matches the exact part number including all alphanumeric designators. Confirm RoHS compliance status through the latest datasheet. Validate that the supplier provides traceable manufacturing origin data consistent with Texas Instruments standards.

Selection Notes

Select this component when a 10-bit width is required for bus interfacing tasks. The 3-state output feature allows for direct connection to shared data lines without additional buffering. Consider the SOIC-24 package dimensions for PCB layout constraints. Verify that the system power supply remains strictly within the 4.75 V to 5.25 V operational window to ensure correct logic levels.

Part Context

This device is part of the broader CY74FCT821T family of bus interface flip-flops. It shares functional similarities with other members of the FCT series but is distinct in its 10-bit architecture. The component serves as a specialized solution for applications needing more than standard 8-bit or 9-bit latch capacities while maintaining compatibility with existing FCT ecosystem standards.

Replacement Considerations

Consult official substitution guides for equivalent parts within the same logic family. Verify pinout compatibility and electrical characteristics before swapping components. Ensure any alternative part meets the same voltage and temperature specifications.
