CY74FCT2374CTSOCG4

Overview

The CY74FCT2374CTSOCG4 is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the FCT logic series. It features eight positive-edge-triggered D-type latches with tri-state outputs and a dedicated clear input. The device operates within a supply voltage range of 4.75 V to 5.25 V and utilizes a 20-pin SOIC package. Key electrical parameters include a propagation delay of 5.2 ns, high-level output current of -32 mA, and low-level output current of 64 mA. It supports TTL-compatible inputs and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering for data capture.
• Tri-state outputs enable direct connection to bus systems without external drivers.
• Integrated clear input allows asynchronous resetting of all latch states.
• Functionally compatible with existing FCT and F Logic families for design continuity.

Applications

• Parallel-to-serial data conversion in communication interfaces
• Register stages in microprocessor-based memory systems
• I/O buffering for peripheral device control

Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance status as specified by the manufacturer. Ensure the SOIC-20 package variant matches the required PCB footprint and thermal management specifications. Confirm that the intended application environment remains within the specified -40°C to +85°C operating temperature range to guarantee reliable performance.

Selection Notes

Select this component when designing systems requiring high-speed data latching with bus-compatible outputs. The FCT series offers superior switching speeds compared to standard CMOS logic while maintaining compatibility with TTL input levels. Consider the 25-ohm output series resistors if transmission-line reflection noise reduction is necessary for signal integrity in high-frequency applications.

Part Context

This device is part of the CY74FCT374T family, representing advanced Fast CMOS technology. It provides enhanced performance characteristics suitable for complex digital logic designs. The integration of tri-state outputs simplifies circuit topology by eliminating the need for additional buffer components, thereby reducing board space and assembly costs.
