IDT74FCT377TQ

Overview

The IDT74FCT377TQ is an 8-bit D-type flip-flop manufactured by Integrated Device Technology Inc. It features positive edge triggering and a 3-state output interface, housed in a 20-lead SSOP package with a width of 5.30mm. The device operates on a 5V supply voltage and supports a maximum operating frequency of 71.4 MHz. Key electrical parameters include a propagation delay of 13 ns at nominal supply, a load capacitance of 50 pF, and a maximum output current of 0.048 A. The component functions within a temperature range of -40°C to 85°C.

Feature Summary

• Eight-function D flip-flop architecture with positive edge clock triggering for sequential data storage.
• Three-state output capability allowing direct bus interfacing and system line sharing.
• CMOS technology implementation ensuring compatibility with standard logic families.

Applications

• Parallel-to-serial data conversion circuits
• Register file storage elements in digital systems
• Timing synchronization and pulse stretching applications

Procurement Notes

Verify the specific manufacturer source, as Integrated Device Technology assets were acquired by Renesas Electronics. Confirm that the component meets current environmental compliance standards, noting that original documentation may indicate non-compliance with certain regulations. Ensure the SSOP package dimensions match the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when an 8-bit parallel register with tri-state outputs is required for 5V logic systems. The SSOP package is suitable for surface-mount assembly where space efficiency is prioritized over through-hole mounting options. Consider the 71.4 MHz speed limit and 13 ns delay characteristics against system timing constraints to ensure signal integrity.

Part Context

This part belongs to the 74FCT series of high-speed CMOS logic devices. The FCT designation indicates Fast CMOS technology, offering performance comparable to LS-TTL but with lower power consumption. The 377 suffix specifically denotes an octal D-type flip-flop configuration, distinguishing it from latches or other logic gates within the same family.

Replacement Considerations

Check for equivalents from Renesas Electronics following the corporate acquisition. Verify pinout compatibility and electrical specifications against alternative manufacturers' 8-bit D-flip-flops in SSOP-20 packages to ensure functional interchangeability without circuit redesign.
