CY74FCT377ATSOC

Overview

The CY74FCT377ATSOC is an octal D-type flip-flop register manufactured by Texas Instruments, belonging to the FCT logic series. It features eight edge-triggered D-type flip-flops with individual data inputs and a common buffered clock input. The device includes a clock-enable function for address and data synchronization. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a wide operating temperature range from -40°C to +85°C. The component utilizes SOIC-20 surface-mount packaging and provides non-inverting outputs.

Feature Summary

• Contains eight edge-triggered D-type flip-flops with individual data inputs
• Includes clock-enable functionality for synchronized data loading
• Supports partial-power-down mode via Ioff circuitry to prevent backflow current
• Fully compatible with TTL input and output logic levels

Applications

• Address and data synchronization in digital systems
• Octal register applications requiring edge-triggered storage
• Partial-power-down mode operations in electronic circuits

Procurement Notes

Verify the specific suffix ATSOC against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental files. Ensure the component matches the required operating temperature range and voltage specifications for the target application before procurement.

Selection Notes

Select this component when an octal register with enable control is required for high-speed digital designs. The FCT series offers performance comparable to LS-TTL with CMOS power consumption. Verify that the SOIC-20 package fits the PCB layout constraints. Consider the Ioff feature if the design requires safe partial-power-down capabilities without external isolation.

Part Context

This part belongs to the CY74FCT family of high-speed CMOS logic devices produced by Texas Instruments. The FCT series is designed to provide performance similar to Low-power Schottky TTL while maintaining CMOS power advantages. These components are widely used in general-purpose digital logic applications requiring reliable data storage and transfer.

Replacement Considerations

Check for CY74FCT377TQCT as a potential alternative with SSOP-20 packaging. Verify functional equivalence regarding pinout and electrical characteristics before substitution.
