CY74FCT646TSOCT

Overview

The CY74FCT646TSOCT is an octal registered bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features TTL-compatible input and output levels. The device provides three-state outputs with a low-level output current of 64 mA and a high-level output current of -32 mA. It exhibits a propagation delay of 9 ns and functions as a non-inverting circuit. The component is housed in a 24-pin SOIC package and supports surface-mount installation. It is designed for operation across a temperature range from -40°C to +85°C.

Feature Summary

• Integrates eight D-type registers with bus transceiver functionality for data storage and bidirectional transfer.
• Provides three-state outputs to facilitate efficient bus line management and system isolation.
• Ensures signal integrity through TTL-compatible logic levels for both inputs and outputs.

Applications

• High-performance register file implementations
• Clock buffering and timing circuits
• Bus-oriented memory architectures

Procurement Notes

Verify the specific suffix 'SOCT' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the ordering information matches the required pinout and electrical specifications for the target application design.

Selection Notes

Select this component when an octal registered interface with three-state capability is required. It is suitable for designs needing TTL compatibility and moderate speed performance.
