MC100EL51DG

Flip Flops Overview

The MC100EL51DG is a single D-type flip-flop from the onsemi 100EL series, designed for high-speed digital applications. It features differential outputs and accepts single-ended inputs with inverting/non-inverting polarity options. The device operates within a supply voltage range of -4.2 V to -5.7 V and supports clock frequencies up to 2.8 GHz. Key electrical parameters include a propagation delay of 0.565 ns and a static current consumption of 29 mA. It is housed in an 8-SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Supports high-frequency operation with a maximum clock rate of 2.8 GHz
• Provides differential outputs for improved signal integrity in noise-sensitive environments
• Includes reset functionality for controlled state initialization
• Features input clamping circuits to maintain stable output states during open-input conditions

Flip Flops Applications

• Clock distribution networks utilizing ECL logic families
• Digital signal processing circuits demanding low propagation delay
• Communication equipment interfaces requiring differential signaling

Flip Flops Procurement Notes

Verify that the specific order matches the MC100EL51DG part number, as suffixes may indicate different packaging or tape-and-reel configurations. Confirm compliance with RoHS3 standards if environmental regulations apply to the project. Ensure the procurement channel provides valid datasheets and material declarations. Check for any recent product change notices that might affect pinout or electrical characteristics. Validate that the supplier offers genuine onsemi components to avoid counterfeit risks.

Flip Flops Selection Notes

Select this component when a single D-type flip-flop with differential outputs is required for ECL-based designs. It is suitable for systems needing a propagation delay under 0.6 ns and operation at voltages between -4.2 V and -5.7 V. Consider the 8-SOIC package for surface-mount assembly constraints. Compare against the MC10EP51DG if higher speed (3 GHz) or wider voltage ranges are necessary, noting differences in power consumption and series specifications.

Flip Flops Part Context

This device belongs to the MC100EL family of emitter-coupled logic (ECL) integrated circuits. It serves as a fundamental sequential logic element within high-performance digital systems. The 100EL series is characterized by its compatibility with standard ECL power supplies and its ability to interface with other high-speed logic families. It complements other devices in the onsemi portfolio such as multiplexers and gates designed for similar voltage and speed requirements.

Flip Flops Replacement Considerations

The MC10EL51DTG is a pin-compatible alternative in the 10EL series, though it is listed as obsolete. For active replacements, consider the MC100EP51DG, which offers higher speed performance but differs in power consumption and voltage tolerance. Verify functional equivalence regarding reset behavior and output drive capabilities before substitution.
