CY74FCT377ATQCT

Overview

The CY74FCT377ATQCT is an octal D-type flip-flop with enable manufactured by Texas Instruments. It belongs to the FCT logic series and features eight triggered D-type flip-flops with individual data inputs and a common buffered clock input. The device operates within a supply voltage range of 4.75 V to 5.25 V, supporting TTL input and output levels. It is housed in a 20-SSOP package suitable for surface mount installation. The component functions as a non-inverting register with tri-state outputs.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops
• Common buffered clock input for synchronized data loading
• Tri-state outputs compatible with bus-oriented systems
• TTL input and output level compatibility

Applications

• High-speed digital data storage applications
• Bus-oriented memory register implementations
• Parallel-to-serial data conversion circuits
• Timing control and synchronization logic

Procurement Notes

Verify the specific suffix 'ATQCT' against the manufacturer's current product status documentation to confirm availability and compliance. Ensure that the 20-SSOP package dimensions align with the target PCB footprint requirements. Cross-reference the humidity sensitivity classification and recommended reflow soldering profiles with assembly guidelines to prevent component damage during manufacturing processes.

Selection Notes

Select this component when an octal register with a single common clock source is required for high-speed data latching. The FCT series offers performance comparable to standard logic families while maintaining CMOS power consumption characteristics. Consider the tri-state output capability if the design necessitates multiple devices sharing a common data bus without additional external gating circuitry.

Part Context

This part is a member of the Texas Instruments 74FCT family, designed for high-speed digital applications. It serves as a functional equivalent to other octal D-type flip-flops within the industry standard logic hierarchy. The device provides a robust solution for system designers requiring reliable data retention and fast switching speeds in compact surface-mount packages.
