MC100EL31DR2G

Flip Flops Overview

The MC100EL31DR2G is a high-speed 5V ECL D-type flip-flop manufactured by onsemi. It features a single circuit with positive-edge triggering and includes set and reset functions for flexible data handling. The device operates within a supply voltage range of -4.2V to -5.7V and supports clock frequencies up to 2.8 GHz. Designed for surface-mount applications, it is housed in an 8-SOIC package (0.154 inch width). The component ensures reliable performance across an operating temperature range of -40°C to +85°C, making it suitable for demanding digital logic environments requiring precise timing control.

Flip Flops Feature Summary

• Positive-edge triggered D-type flip-flop architecture
• Integrated asynchronous set and reset control inputs
• High-frequency operation supporting up to 2.8 GHz clock rates
• Complementary output configuration for differential signaling

Flip Flops Applications

• High-speed serial communication link synchronization
• Data sampling circuits in telecommunications equipment
• Frequency division and phase alignment in clock distribution networks
• Digital signal processing pipeline register stages

Flip Flops Procurement Notes

Verify the specific ordering suffix DR2G to confirm the SOIC-8 tape-and-reel packaging format. Ensure compatibility with standard -5.2V ECL power supplies and check that the thermal management solution accommodates the specified operating temperature range. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Flip Flops Selection Notes

Select this component when a single-bit storage element with independent set and reset capabilities is required in a 5V ECL environment. The 2.8 GHz maximum frequency rating makes it appropriate for high-bandwidth data paths. Consider the 8-SOIC package dimensions for PCB layout constraints and ensure the design supports the necessary current sinking and sourcing requirements for ECL logic levels.

Flip Flops Part Context

This part belongs to the MC100EL series of 5V ECL logic devices from onsemi. It serves as a fundamental building block for sequential logic in high-speed digital systems. The DR2G suffix indicates a specific reel-packaged variant within the broader MC100EL31 family, which also includes tube-packaged options like the MC100EL31DG.

Flip Flops Replacement Considerations

MC100EL31DG: Identical functional specifications but packaged in tubes instead of tape-and-reel. MC100EL31DTG: Alternative tube packaging variant. Verify pinout and electrical characteristics match before substitution.
