74FCT377CTSOG

Overview

The 74FCT377CTSOG is an octal D-type flip-flop with 3-state outputs manufactured by Renesas Electronics. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum clock frequency of 70 MHz. The device exhibits a typical propagation delay of 13 ns at nominal supply voltage. It is housed in a 20-pin plastic Small Outline Package (SOP) and supports a load capacitance of 50 pF. The component provides a low-level output current of 48 mA and functions as a high-performance logic register suitable for synchronous data storage applications.

Feature Summary

• Octal D-type flip-flop architecture providing eight independent data storage elements
• Three-state outputs enabling direct bus connection without external buffers
• High-speed CMOS technology supporting clock frequencies up to 70 MHz
• Compatible with standard TTL and CMOS logic families

Applications

• Parallel-to-serial data conversion circuits
• Synchronous state machines and control logic
• Data buffering on system buses
• Timing delay compensation networks

Procurement Notes

Verify the specific suffix 'CTSOG' against official Renesas documentation to confirm package type, temperature range, and RoHS compliance status. Ensure that the ordering information matches the exact pinout and electrical characteristics required for the target design. Cross-reference the manufacturer's latest datasheet to confirm availability and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when an octal register with high-speed performance and bus-compatible outputs is required. The 70 MHz clock capability makes it suitable for fast digital systems. Consider the 20-pin SOP package constraints regarding PCB space and thermal management. Verify that the 5V supply voltage aligns with the system power rails and that the 48 mA drive strength meets the load requirements.

Part Context

This part belongs to the 74FCT series of Fast CMOS logic devices produced by Renesas Electronics. The FCT series bridges the speed gap between standard TTL and advanced CMOS technologies. The 74FCT377 variant specifically implements octal D-type flip-flops, distinguishing it from latches or buffer variants within the same logical family classification.

Replacement Considerations

Official cross-references may include IDT74FCT377CTSOG. Verify functional equivalence and pin compatibility with alternative manufacturers such as Texas Instruments or ON Semiconductor before substitution.
