CY74FCT377ATSOCT

Overview

The CY74FCT377ATSOCT 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 a propagation delay of 5.2 ns. The device provides high drive capability with a low-level output current of 64 mA and a high-level output current of -32 mA. It is housed in a 20-pin SOIC package and supports surface-mount installation. The component functions as a non-inverting register with single-ended inputs and outputs, designed for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture with integrated enable control
• High-current CMOS output drivers for robust signal transmission
• TTL-compatible input logic levels for broad interface compatibility

Applications

• Parallel data storage in digital systems
• Bus-oriented memory applications
• Register file implementations in computing hardware

Procurement Notes

Verify the specific suffix 'AT' against the manufacturer's official documentation to confirm the exact temperature grade and packaging variant. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the part number with the latest datasheet revision to confirm compliance with RoHS standards and any recent design changes before finalizing orders.

Selection Notes

Select this component when an octal storage element with enable functionality is required in FCT logic designs. Consider the 5.2 ns propagation delay and 64 mA sink current for timing and load requirements. Verify that the SOIC-20 package fits the PCB layout constraints. Ensure the operating environment stays within the specified -40°C to +85°C range and that the 5V supply tolerance is maintained for reliable operation.

Part Context

This part belongs to the Texas Instruments FCT (Fast CMOS Technology) logic family, which bridges the performance gap between standard CMOS and ECL technologies. The FCT series is characterized by high speed and TTL-compatible inputs while maintaining CMOS noise immunity. The CY74FCT377 specifically serves as a parallel-to-serial or parallel data holding element within this high-performance logic ecosystem.

Replacement Considerations

Check for CY74FCT377CTSOCT as a potential alternative within the same package and electrical specifications. Verify if other manufacturers offer pin-compatible octal D-flip-flops with similar enable features and drive currents. Confirm that any substitute maintains the same FCT logic family characteristics and voltage tolerances.
