MC100EL31DR2

Flip Flops Overview

The MC100EL31DR2G is a 5 V ECL D Flip-Flop with Set and Reset functions, manufactured by onsemi. It operates within a supply voltage range of -4.2 V to -5.7 V and supports clock frequencies up to 2.8 GHz. The device features a single element with one bit per element, utilizing positive-edge triggering. It provides complementary outputs and includes preset and reset capabilities. The component is housed in an 8-SOIC package (0.154" width) designed for surface mount installation. Static current consumption is specified at 32 mA. The operating temperature range extends from -40°C to +85°C.

Flip Flops Procurement Notes

Verify the complete part number suffix, as 'MC100EL31DR2' typically corresponds to 'MC100EL31DR2G' for tape-and-reel packaging or 'MC100EL31DG' for tube packaging. Confirm RoHS compliance status and specific package variant requirements before ordering. Ensure supply chain sources provide official manufacturer documentation to validate authenticity and revision levels.

Flip Flops Selection Notes

Select this component when a high-speed, low-voltage ECL D flip-flop with asynchronous control is required. The 2.8 GHz capability suits demanding timing applications. Verify that the system power supply aligns with the -4.2 V to -5.7 V operational range. Consider the 8-SOIC package dimensions for PCB layout constraints and thermal management requirements relative to the 32 mA static current draw.

Flip Flops Part Context

This device belongs to the MC100EL series of 5 V ECL logic components produced by onsemi. The series encompasses various logic families including buffers, drivers, and sequential elements. The MC100EL31 specifically addresses sequential logic needs within high-speed communication and computing systems requiring reliable data latching and transfer characteristics.

Flip Flops Replacement Considerations

Public confirmed substitutes include MC100EL31D, MC100EL31DG, and MC100EL31DTG. These variants share identical functional specifications but differ in packaging formats such as tubes or tape-and-reel configurations.
