CY74FCT374CTQCT

Overview

The CY74FCT374CTQCT is an octal D-type flip-flop manufactured by Texas Instruments, featuring positive-edge triggering and three-state outputs. It operates within a supply voltage range of 4.75V to 5.25V and supports a maximum propagation delay of 10ns at 5V with a 50pF load. The device provides high drive capability with output currents of 32mA (high) and 64mA (low), while maintaining a static current of 200µA. Designed for surface-mount applications, it is housed in a 20-SSOP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Positive-edge triggered data storage for synchronous digital systems
• Three-state non-inverting outputs enabling bus-oriented architectures
• High-drive output capability supporting direct interface to TTL loads

Applications

• Parallel-to-serial data conversion circuits
• Buffered register stages in communication interfaces
• I/O port expansion for microprocessor systems

Procurement Notes

Verify the specific suffix 'CTQCT' against the official datasheet to confirm the QSOP-20 package variant and commercial grade temperature rating. Ensure compatibility with existing PCB footprints for 20-pin narrow body packages. Confirm RoHS compliance status matches project requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring octal latching with high-current drive capabilities. It is suitable for applications needing positive-edge triggering and three-state control on a single chip. Consider the 10ns propagation delay and 200µA static current for power and timing constraints in 5V logic environments.

Part Context

This part belongs to the 74FCT series of fast CMOS logic devices produced by Texas Instruments. The FCT family bridges the performance gap between standard TTL and CMOS technologies, offering speeds comparable to LS-TTL with lower power consumption. The CY prefix indicates Cypress Semiconductor origin prior to acquisition, now managed under TI's logic portfolio.

Replacement Considerations

The CY74FCT374ATQCT serves as a verified alternative within the same series, typically differing only in manufacturing lot or minor process revisions rather than functional parameters.
