CY74FCT377CTSOCE4

Overview

The CY74FCT377CTSOCE4 is an octal D-type flip-flop with clock enable, part of the Texas Instruments FCT logic family. It features eight edge-triggered D-type flip-flops with individual data inputs and a common buffered clock input. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 10 ns at 5 V with 50 pF load. It provides high drive capability with -64 mA low-level output current and -32 mA high-level output current. The component is housed in a 20-pin SOIC package and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Includes clock enable functionality for address and data synchronization
• Supports partial-power-down mode operation via Ioff circuitry
• Provides ESD protection exceeding JESD 22 standards

Applications

• Address and data synchronization circuits
• Partial-power-down applications requiring output disabling
• Edge-triggered register designs

Procurement Notes

Verify the 'E4' suffix indicates lead-free composition and RoHS compliance per manufacturer specifications. Confirm the SOIC-20 package dimensions match design constraints. Ensure the operating temperature range meets system requirements. Cross-reference the datasheet revision date to confirm current electrical characteristics. Validate that the specific ordering code matches the required tape-and-reel or tube packaging format.

Selection Notes

Select this component when high-speed octal latching with clock enable is required. The FCT series offers compatibility with TTL levels while maintaining CMOS power efficiency. Consider the -64 mA sink current for driving heavy loads. Verify interface compatibility with existing system clocks. Evaluate thermal performance within the specified ambient temperature limits.

Part Context

This device belongs to the CY74FCT377T series of octal registers. It shares functional similarities with other FCT family members but includes specific clock enable control. The E4 suffix denotes environmental compliance modifications. It serves as a digital storage element in high-speed logic systems requiring synchronized data capture.

Replacement Considerations

CY74FCT377CTSOCT is the non-compliant equivalent. SN74F377A offers similar functionality but differs in drive strength and speed specifications.
