CY74FCT2374TSOCE4

Overview

The CY74FCT2374TSOCE4 is an octal D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features a propagation delay of 4 ns at 5 V with 50 pF load. The device provides high-drive outputs capable of sourcing -32 mA and sinking 64 mA. It is housed in a 20-pin SOIC package (0.295 inch width) and supports surface mount installation. The component functions as a positive-edge triggered register with non-inverting outputs, designed for high-speed digital applications.

Feature Summary

• Octal D-type configuration with positive edge triggering
• High-drive 3-state outputs for bus driving
• Fast propagation delay for high-speed data transfer
• TTL-compatible input levels

Applications

• Parallel-to-serial data conversion circuits
• Buffered register stages in high-speed systems
• Clock domain crossing synchronization
• Data acquisition system storage

Procurement Notes

Verify the specific suffix E4 indicates RoHS compliance status according to the manufacturer's current documentation. Confirm the package dimensions match the 20-SOIC specification with 0.295-inch width. Ensure the operating temperature range meets the application requirements of -40°C to +85°C. Cross-reference the datasheet revision date to confirm electrical characteristics remain unchanged.

Selection Notes

Select this component when an octal register with high drive capability is required. The 3-state output allows direct connection to bidirectional buses. The fast switching speed suits applications demanding low latency. Verify that the power supply voltage remains strictly within the 4.75 V to 5.25 V window to ensure reliable operation and prevent damage.

Part Context

This part belongs to the Texas Instruments 74FCT logic family, which combines CMOS density with TTL compatibility. The FCT series is optimized for high-speed performance while maintaining standard logic interface levels. The CY74FCT2374 variant specifically provides registered buffering capabilities for complex digital designs requiring precise timing control.

Replacement Considerations

The CY74FCT2374TSOC is a compatible alternative without the E4 suffix. Verify if the suffix change affects RoHS status or packaging details. Ensure pinout compatibility remains identical between the base model and the replacement variant before substitution.
