MC100EL56DWR2G

Overview

The MC100EL56DWR2G is a high-speed, fully differential 4:1 multiplexer from the onsemi 100ECL series. It operates within a supply voltage range of 3.0V to 5.5V and supports both PECL and NECL logic families. The device features a typical propagation delay of 360ps and a maximum operating frequency exceeding 3GHz. It includes dedicated VBB pins for internal bias generation, facilitating AC coupling and single-ended interface configurations. The component is housed in a 20-SOIC (0.295", 7.50mm Width) package with an industrial temperature range of -40°C to 85°C.

Feature Summary

• Fully differential architecture designed for low skew clock and sensitive signal multiplexing applications
• Integrated VBB pin providing internal bias voltage for input re-biasing and reference levels
• Robust input protection featuring open-circuit defaults and safety clamping mechanisms

Applications

• High-speed clock distribution networks requiring minimal skew
• Data path selection in telecommunications infrastructure
• Random logic applications utilizing differential signaling

Procurement Notes

Verify the specific suffix 'R2G' confirms the reel packaging format when sourcing. Confirm RoHS compliance status as required by project specifications. Ensure the SOIC-20 footprint matches the PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any potential lifecycle changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component for designs requiring high-frequency differential signal routing with low propagation delay. The wide supply voltage compatibility allows integration into systems using either standard 5V or lower voltage ECL/PECL standards. The inclusion of separate and common select inputs provides flexibility for complex data path management compared to simpler multiplexer variants.

Part Context

This part belongs to the 100ECL family of high-performance emitter-coupled logic devices. It shares functional similarities with the MC10EP56 but offers enhanced temperature compensation characteristics typical of the 100-series designation. The device serves as a critical interconnect element in high-speed digital systems where signal integrity and timing precision are paramount.

Replacement Considerations

The MC10EP56DTG is documented as a parameter-equivalent alternative within the same product family.
