MC10EL35DR2

Flip Flops Overview

The MC10EL35DR2 is a high-speed ECL JK flip-flop manufactured by onsemi, belonging to the MC10EL series. It features a single JK-type element with positive-edge triggering and differential outputs. The device operates within a supply voltage range of -4.2V to -5.7V and supports a clock frequency up to 2.2 GHz. It includes an asynchronous reset function and is housed in an 8-SOIC surface-mount package. The component draws a static current of 32 mA and functions reliably across a temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Supports high-speed data processing with a maximum clock frequency of 2.2 GHz
• Features differential outputs for improved signal integrity in ECL applications
• Includes an asynchronous reset pin activated by a logic HIGH signal
• Operates in standard NECL mode with negative supply voltage

Flip Flops Applications

• High-speed digital timing circuits
• ECL-based data storage systems
• Clock distribution networks requiring precise edge triggering
• Telecommunications equipment utilizing ECL logic families

Flip Flops Procurement Notes

Verify the specific suffix DR2 against official datasheets to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as historical data indicates potential non-compliance for certain variants. Check lead times and availability through authorized distributors, noting that this part may be subject to obsolescence or limited stock conditions. Ensure compatibility with existing -5V ECL power supplies and thermal management requirements for SOIC-8 packaging.

Flip Flops Selection Notes

Select the MC10EL35DR2 when designing systems requiring fast JK flip-flops with differential outputs in the ECL domain. It is suitable for applications needing positive-edge triggering and asynchronous reset capabilities. Consider the 32 mA static current draw for power budgeting. Compare with the MC10EP35 series if PECL operation (positive supply) is required instead of NECL. Ensure the 8-SOIC package fits the PCB layout constraints.

Flip Flops Part Context

The MC10EL35DR2 is part of onsemi's MC10EL family of ECL logic devices. This series provides high-speed performance for demanding digital applications. The EL designation typically refers to standard ECL operation with negative supply voltages. It serves as a fundamental building block for sequential logic in high-frequency systems, offering reliable state retention and fast transition times compared to lower-speed logic families.

Flip Flops Replacement Considerations

The MC10EP35DTR2G is a documented alternative from the same manufacturer, offering similar JK flip-flop functionality but potentially in a TSSOP-8 package with different electrical characteristics such as a 0.49 ns propagation delay. Verify pinout compatibility and voltage level matching before substitution.
