74FCT374CTSOG8

Overview

The IDT74FCT374CTSOG8 is an octal D-type flip-flop featuring three-state outputs, manufactured using Fast CMOS technology. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum propagation delay of 5.2 ns at 50 pF load capacitance. The device provides high drive capabilities with output currents of -32 mA (high) and 64 mA (low). It is housed in a 20-pin SOIC package and functions over an industrial temperature range of -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture with positive edge triggering for efficient data storage.
• Three-state outputs enable direct connection to bus systems without external buffers.
• Fast CMOS construction ensures low power consumption while maintaining TTL-compatible input and output levels.

Applications

• Parallel data buffering in high-speed digital communication interfaces.
• Register stages within microprocessor-based system architectures.
• Data acquisition systems requiring synchronized signal latching.

Procurement Notes

Verify the specific suffix 'SOG8' against official manufacturer documentation to confirm package dimensions and lead finish specifications. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring octal data storage with bus-compatible outputs. Consider the 5.2 ns propagation delay and 5V operating voltage constraints. Verify that the SOIC-20 package fits the available board space and assembly capabilities.

Part Context

This part belongs to the 74FCT logic family, which bridges the performance gap between standard TTL and CMOS technologies. It offers faster switching speeds than conventional 74LS series devices while maintaining lower power dissipation characteristics suitable for dense integrated circuit designs.

Replacement Considerations

Cross-reference with CY74FCT374CTSO from Texas Instruments for functional equivalence. Confirm pinout compatibility and electrical parameter alignment before substituting components in existing designs.
