CY74FCT377CTQCT

Overview

The CY74FCT377CTQCT is an octal D-type flip-flop manufactured by Texas Instruments within the FCT logic series. It features a single circuit with eight non-inverting inputs and outputs, housed in a 20-pin SSOP package for surface mount installation. The device operates on a supply voltage ranging from 4.75 V to 5.25 V, supporting TTL input levels. Key electrical parameters include a propagation delay of 6.5 ns, high-level output current of -32 mA, and low-level output current of 64 mA. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture providing eight-bit data storage capability
• Positive-edge triggering mechanism for synchronous data capture
• TTL-compatible input thresholds ensuring interface versatility
• High-drive output capability suitable for bus driving applications

Applications

• Parallel data storage registers
• Shift register configurations
• Bus interface buffering
• Timing control circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure packaging integrity matches specified reel or cut tape requirements. Cross-reference datasheet revisions to confirm parameter consistency. Validate pinout alignment with target PCB footprint design specifications.

Selection Notes

Select this component when requiring an octal edge-triggered storage element with TTL compatibility. Consider the SSOP package constraints for board space limitations. Evaluate the 6.5 ns propagation delay against system timing budgets. Compare drive strength requirements against load capacitance specifications. Verify operating temperature range suitability for the intended environment.

Part Context

This part belongs to the Texas Instruments FCT (Fast CMOS) family, designed for high-speed digital applications. It complements other logic devices like latches and buffers within the same ecosystem. The CY74FCT377 variant specifically provides flip-flop functionality distinct from the 373 latch or 374 tri-state variants. It serves as a core building block for sequential logic designs in industrial and consumer electronics.
