CY74FCT377CTSOC

Overview

The CY74FCT377CTSOC is an octal D-type flip-flop with enable, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features single-ended inputs and outputs. 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 is housed in a 20-pin SOIC package designed for surface-mount installation. The component supports operation across a temperature range from -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture with positive edge triggering
• Enable control functionality for data latching management
• Single-ended input and output signal configuration
• Non-inverting logic polarity for direct signal transmission

Applications

• Parallel data storage and buffering in digital systems
• Register file implementation in microprocessor interfaces
• Data latch circuits for temporary state retention
• Synchronous logic design requiring eight-bit word handling

Procurement Notes

Verify the specific suffix 'CTSOCT' against official Texas Instruments documentation to confirm tape-and-reel packaging and lead-free status. Confirm RoHS compliance details directly from the manufacturer datasheet. Check for obsolescence notices or lifecycle changes prior to procurement. Ensure the ordering part number matches the exact package and thermal grade requirements for the target application.

Selection Notes

Select this component when an octal register with enable control is required in FCT logic designs. Compare against CY74FCT374TQCT if three-state outputs are needed instead of standard single-ended outputs. Evaluate the 5.2 ns propagation delay against system timing constraints. Consider the SOIC-20 package dimensions for PCB layout compatibility and thermal dissipation needs.

Part Context

This device belongs to the Texas Instruments 74FCT series, which combines CMOS density with TTL-compatible speeds. The CY74FCT377 variant specifically provides octal storage capabilities. It is distinct from the CY74FCT574TSOC, which offers three-state outputs rather than standard enabled outputs. The family targets high-speed digital applications requiring reliable data storage.

Replacement Considerations

Public confirmed substitute part numbers: CY74FCT377CTSOCE4, CY74FCT377CTSOCG4.
