MC100EL56DW

Overview

The MC100EL56DW is a dual differential 2:1 multiplexer from the onsemi 100 series, designed for high-speed signal routing in ECL logic applications. It features temperature compensation and supports both PECL and NECL operating modes with wide voltage ranges. The device includes internal VBB generation for biasing and input clamping for protection. It operates within a -40°C to +85°C temperature range and utilizes a SOIC-20 package.

Feature Summary

• Dual differential 2:1 multiplexing architecture
• Temperature compensated performance
• Internal VBB generation for biasing
• Input clamping protection

Applications

• High-speed clock distribution networks
• Signal routing in telecommunications equipment
• Data acquisition systems requiring low skew
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 Wide package variant. Confirm RoHS compliance status as manufacturing processes evolve. Check for obsolescence notices or lifecycle changes directly from onsemi documentation before finalizing procurement plans.

Selection Notes

Select this component when differential signaling integrity is critical. Ensure supply voltages align with PECL or NECL requirements. Verify that the SOIC-20 footprint matches the PCB layout constraints. Consider thermal management capabilities if operating near maximum temperature limits.

Part Context

Part of the MC100EL series, which offers enhanced performance over legacy ECL devices. The 100 series typically includes temperature compensation for stable timing characteristics across varying environmental conditions. This family targets applications demanding precise signal switching without degradation.

Replacement Considerations

MC10EP56 serves as a functional equivalent within the same product family. Cross-reference pinouts and electrical specifications carefully. Verify package compatibility and ensure substitute parts meet identical speed and voltage requirements.
