74FCT377CTSOG8

Overview

The 74FCT377CTSOG8 is an octal D-type flip-flop with output registers manufactured by Renesas Electronics. It operates within a supply voltage range of 4.5V to 5.5V and features three-state outputs for bus-oriented memory operations. The device supports a maximum clock frequency of 100 MHz and exhibits a typical propagation delay of 6.2 ns. It is housed in a 20-pin SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Three-state outputs enable direct connection to system buses without external drivers
• High-speed performance supporting clock frequencies up to 100 MHz
• Comprehensive latching capability for synchronous data registration

Applications

• Bus-oriented memory register implementations
• Parallel-to-serial data conversion circuits
• Clocked data storage in high-speed digital systems
• Interface logic between microprocessors and peripheral devices

Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm pinout compatibility and electrical characteristics. Ensure that the selected variant matches the required operating temperature range and package dimensions for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring octal data latching with high-speed operation capabilities. The three-state output feature makes it suitable for shared bus architectures where multiple devices must communicate over common lines. Consider the 100 MHz speed rating for applications demanding rapid data transfer rates. Ensure power supply stability within the specified voltage range to maintain signal integrity and timing accuracy.

Part Context

This device belongs to the 74FCT series, which bridges the performance gap between standard TTL and CMOS logic families. The FCT technology offers fast switching speeds while maintaining CMOS low-power consumption characteristics. This specific model provides octal storage functionality, distinguishing it from simpler quad or single-bit flip-flop variants within the broader logic IC portfolio.
