MC100EL51DT

Flip Flops Overview

The MC100EL51DT is a single D-type flip-flop from the onsemi 100EL series, designed for high-speed ECL applications. It features differential clock inputs and supports both positive and negative edge triggering. The device operates within a supply voltage range of -4.2V to -5.7V and delivers a typical propagation delay of 0.565 ns with a maximum clock frequency of 2.8 GHz. Packaged in an 8-TSSOP surface-mount format, it functions across an industrial temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Supports dual-edge triggering via differential clock inputs for flexible timing control
• Provides complementary differential outputs for noise immunity in high-speed circuits
• Includes input clamping circuitry to maintain stable output states during open-input conditions

Flip Flops Applications

• High-speed serial data transmission systems
• Clock distribution networks requiring precise timing alignment
• Buffering and latching stages in ECL-based logic architectures

Flip Flops Procurement Notes

Verify that the specific part number matches the required 8-TSSOP package configuration and lead-free RoHS compliance status. Confirm that the operating voltage requirements align with standard -5V ECL power supplies. Ensure thermal management strategies account for the specified industrial temperature range limits during integration.

Flip Flops Selection Notes

Select this component when differential clock signaling is required to minimize jitter in high-frequency designs. Consider the 8-TSSOP footprint for space-constrained PCB layouts. Evaluate the 2.8 GHz speed capability against system timing budgets to ensure adequate performance margins for signal integrity.

Flip Flops Part Context

This device belongs to the MC100EL family of emitter-coupled logic components. It shares functional similarities with other ECL flip-flops but is distinguished by its specific differential clock interface and 8-TSSOP packaging. It serves as a fundamental building block for synchronous digital systems requiring fast switching speeds.

Flip Flops Replacement Considerations

Direct substitutes include MC100EL51DG (SOIC-8 package) and MC100LVEL51DTR2G (TSSOP-8 package). Verify pinout compatibility and voltage level differences before substitution, particularly regarding the LVEL variant's lower voltage operation.
