MC10EP35DR2

Flip Flops Overview

The MC10EP35DR2 is a high-speed ECL JK flip-flop manufactured by onsemi, belonging to the 10EP series. It features a propagation delay of 410 ps and supports typical operating frequencies exceeding 3 GHz. The device operates in PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) or NECL mode with VEE from -3.0 V to -5.5 V (VCC = 0 V). It includes an asynchronous reset activated by a logic HIGH and provides open-input default states where the Q output defaults LOW. The component is housed in an 8-SOIC package.

Flip Flops Feature Summary

• High-speed ECL JK flip-flop with 410 ps propagation delay
• Supports PECL (3.0 V to 5.5 V) and NECL (-3.0 V to -5.5 V) operation
• Asynchronous reset pin activated by logic HIGH
• Open-input default state ensures Q output defaults LOW

Flip Flops Applications

• High-frequency clock distribution systems
• Fast digital signal processing circuits
• Telecommunications equipment requiring low-latency latching

Flip Flops Procurement Notes

The MC10EP35DR2 is listed as obsolete and no longer manufactured. Verification of availability should focus on surplus distributors or alternative sources, as direct production from onsemi has ceased. Designers must assess end-of-life status for long-term supply chain stability.

Flip Flops Selection Notes

Select the MC10EP35DR2 for applications requiring fast ECL latching with specific voltage levels. Ensure compatibility with PECL or NECL power supplies. Consider the MC10EP35DR2G as a potential lead-free alternative if available, though the base model is discontinued. Verify thermal management for SOIC-8 packages in high-density layouts.

Flip Flops Part Context

This component is part of onsemi's 10EP series, designed for higher speed and lower voltage compared to earlier EL series devices. It serves as a functional equivalent to the EL35 but with improved performance metrics. The 100 Series variants within this family often include temperature compensation features.

Flip Flops Replacement Considerations

The MC10EP35DR2 is obsolete. Direct replacement options may include the MC10EP35DR2G if lead-free compliance is required and stock exists. Other ECL JK flip-flops from the same manufacturer or competitors should be evaluated for pin compatibility and timing specifications.

Flip Flops FAQ

What is the operating voltage range for PECL mode?

In PECL mode, the device operates with VCC between 3.0 V and 5.5 V while VEE is connected to 0 V.

How does the asynchronous reset function?

The reset pin is asynchronous and is activated when a logic HIGH signal is applied.

What is the default state of the Q output if inputs are open?

If inputs are open or at VEE, the Q output will default to a LOW state.
