CY74FCT374CTSOCTG4

Overview

The CY74FCT374CTSOCTG4 is an octal D-type flip-flop register featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and utilizes a 20-pin SOIC package. The device exhibits a propagation delay of 5.2 ns, with high-level output current capability of -32 mA and low-level output current of 64 mA. It supports TTL-compatible inputs and functions across an operating temperature range from -40°C to +85°C.

Feature Summary

• Octal D-type configuration with registered data storage capabilities
• Three-state outputs for efficient bus line driving applications
• TTL-compatible input structure ensuring broad logic compatibility

Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching in digital communication systems
• General-purpose register stages in microprocessor interfaces

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status when sourcing. Confirm the 'C' designation aligns with the required commercial temperature grade (-40°C to +85°C). Ensure the 'SOCT' suffix matches the intended 20-SOIC package variant for PCB footprint compatibility. Cross-reference the manufacturer part number against official TI documentation to validate authenticity and revision history before procurement.

Selection Notes

Select this component for designs requiring high-speed octal data registration with bus-oriented output control. The FCT series offers CMOS performance with TTL input compatibility, simplifying interface design. Consider the 5.2 ns propagation delay for timing-critical paths. Evaluate the 20-SOIC package dimensions against available board space constraints. Verify that the 4.75 V to 5.25 V operating range matches the system power supply specifications.

Part Context

This part belongs to the CY74FCT374T family of octal D-type flip-flops. It shares functional similarities with other FCT registers but differs in packaging and environmental compliance markings. The 'G4' suffix typically denotes lead-free assembly and RoHS compliance, distinguishing it from older non-compliant variants within the same logical family.
