CY74FCT374CTQC

Overview

The CY74FCT374CTQC is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting outputs with three-state capability and a single clock input. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL-compatible inputs. Packaged in a 20-pin SSOP, it ensures data storage on the positive edge of the clock signal. Key electrical parameters include a propagation delay of 10 ns at 5V with 50pF load, high-level output current of -32 mA, and low-level output current of 64 mA. It functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

Octal D-type edge-triggered flip-flop architecture for parallel data storage
Three-state outputs enable bus-oriented memory applications
TTL-compatible inputs simplify interface design
Power-off disable feature prevents floating outputs during power transitions

Applications

Bus-oriented memory implementations
Clock-domain synchronization circuits
Parallel-to-serial data conversion modules

Procurement Notes

Verify the specific package variant and suffix codes against official datasheets to ensure compatibility with board layout requirements. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning. Cross-reference manufacturer part numbers with distributor listings to validate authenticity and traceability. Ensure ordering specifications match the required operational temperature range and electrical characteristics for the target application environment.

Selection Notes

Select this component when designing systems requiring octal data latching with high drive capability and three-state control. The FCT series offers speed comparable to standard 74F logic while maintaining CMOS power efficiency. Consider the 20-pin SSOP package for surface-mount space constraints. Evaluate the 10 ns propagation delay against system timing budgets. Ensure the 5V supply tolerance aligns with the overall power distribution network design.

Part Context

This device is part of the broader 74FCT family of high-speed CMOS logic components. It serves as a fundamental building block for digital data handling within complex integrated circuits. The CY74FCT374CTQC specifically addresses the need for reliable octal storage in telecommunications and computing infrastructure. Its design supports live insertion capabilities when paired with appropriate enable controls.
