MC10EP35DG

Flip Flops Overview

The MC10EP35DG is a single JK flip-flop from the onsemi 10EP series, designed for high-speed ECL applications. It features differential outputs and positive-edge triggering within an 8-SOIC surface-mount package. The device supports PECL operation with VCC ranging from 3.0 V to 5.5 V and NECL operation with VEE from -3.0 V to -5.5 V. It includes an asynchronous reset function and operates across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• JK flip-flop with differential outputs and positive-edge clock triggering
• Supports both PECL (VCC 3.0 V–5.5 V) and NECL (VEE -3.0 V to -5.5 V) modes
• Asynchronous reset input with open-input default state logic
• Surface-mount 8-SOIC package rated for -40°C to +85°C operation

Flip Flops Applications

• High-speed digital signal processing systems
• Clock distribution networks requiring differential signaling
• Telecommunications equipment utilizing ECL logic families

Flip Flops Procurement Notes

Verify that the specific procurement channel provides the 8-SOIC tube packaging indicated in the product parameters. Confirm that the supply voltage rails match the required PECL or NECL configuration before integration. Ensure thermal management aligns with the specified -40°C to +85°C operating range for the target environment.

Flip Flops Selection Notes

Select this component when a single JK flip-flop with differential outputs is required for speeds up to 3 GHz. Compare against the MC10EP35D variant if lead-free compliance is not a primary constraint, as the DG suffix typically denotes RoHS-compliant packaging. Ensure the design accommodates the 50 mA quiescent current draw typical of the 10EP series.

Flip Flops Part Context

This part belongs to the MC10/100EP series, which represents a higher-speed, low-voltage evolution of the earlier EL35 JK flip-flop. The 10EP family is optimized for performance in PECL and NECL environments, offering faster propagation delays compared to legacy ECL counterparts while maintaining compatibility with standard ECL power supplies.

Flip Flops Replacement Considerations

Direct replacements include the MC10EP35D for non-RoHS applications or the MC10EL35 for legacy designs. When substituting, verify pinout compatibility and ensure the new component supports the required differential output swing and power supply voltage ranges.

Flip Flops FAQ

What is the difference between PECL and NECL operation for this device?

In PECL mode, VCC is set between 3.0 V and 5.5 V with VEE at 0 V. In NECL mode, VCC is at 0 V and VEE is set between -3.0 V and -5.5 V.

How does the device behave when inputs are left open?

The device has an open-input default state where the Q output will default LOW if inputs are open or connected to VEE.

Is the reset function synchronous or asynchronous?

The reset pin is asynchronous and is activated by a logic HIGH signal, independent of the clock edge.
