CD74FCT374M

Overview

The CD74FCT374M is an octal D-type flip-flop register manufactured by Texas Instruments, belonging to the FCT logic series. It features eight independent D-type flip-flops with three-state outputs, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.75V to 5.25V and supports a maximum load capacitance of 50pF. Key electrical specifications include a propagation delay of 5.2ns at nominal supply, high-level output current of -32mA, low-level output current of 64mA, and static current of 8µA. It functions across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Octal D-type configuration providing eight independent data storage elements
• Three-state outputs enabling direct bus line interfacing
• CMOS BiC technology for compatibility with TTL inputs

Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching digital signals on system buses
• General-purpose register applications in embedded systems

Procurement Notes

Verify the specific manufacturer designation when sourcing, as Renesas also produces equivalent parts under the same model number. Confirm RoHS compliance status, as some variants may not meet current environmental standards. Ensure the package type matches the required PCB footprint and that the operating temperature range aligns with the target application environment.

Selection Notes

Select this component for designs requiring high-speed octal latching with strong drive capabilities. Compare against SN74F374 variants if lower power consumption is prioritized over speed. Consider the 5.2ns propagation delay for timing-critical paths. Verify input compatibility with the driving logic family to ensure reliable signal integrity without additional level shifting.

Part Context

This part belongs to the FCT (Fast CMOS) family, bridging the performance gap between standard CMOS and high-speed TTL logic. It offers faster switching speeds than standard 74HC series devices while maintaining CMOS power efficiency. The octal register architecture allows for efficient management of wide data buses in microprocessor-based systems.
