MC100EL56DWG

Overview

The MC100EL56DWG is a dual differential 2:1 multiplexer from the onsemi 100LVEL series, designed for high-speed signal routing in ECL logic applications. It operates within a supply voltage range of -3.0 V to -5.5 V (Vee) with Vcc at 0 V, supporting NECL mode functionality. The device features separate and common select inputs to accommodate data path and random logic requirements. It is housed in a 20-pin SOIC package and is rated for operation between -40°C and +85°C.

Feature Summary

• Dual differential 2:1 multiplexing architecture for high-speed signal selection
• Temperature-compensated design inherent to the 100LVEL series for stable performance
• Separate and common select input configurations for flexible logic integration

Applications

• Low skew clock signal multiplexing
• Skew-sensitive signal routing systems
• High-speed data path switching

Procurement Notes

Verify current availability status as the MC100EP56MNG variant is noted as obsolete; confirm lead times with authorized distributors. Ensure the specific DWG suffix corresponds to the required SOIC-20 packaging and RoHS compliance standards before finalizing procurement orders.

Selection Notes

Select this component for designs requiring differential ECL multiplexing with temperature compensation. Verify that the system power supply aligns with the -3.0 V to -5.5 V negative rail requirement. Confirm that the 20-pin SOIC footprint fits the PCB layout constraints compared to alternative QFN or TSSOP packages.
