MC100LVEL56DWG

Overview

The MC100LVEL56DWG is a dual differential 2:1 multiplexer from the MC100LVEL series, manufactured by onsemi. It operates within a supply voltage range of 3.0 V to 5.5 V and supports ECL logic families. The device features a propagation delay of 760 ps and functions across an operating temperature range of -40°C to +85°C. It is housed in a 20-pin SOIC-Wide package with surface mount installation.

Feature Summary

• Dual differential data paths for high-speed signal routing
• Wide operating voltage compatibility with standard ECL power supplies
• Temperature-compensated internal biasing for stable performance

Applications

• Low skew clock signal multiplexing
• High-frequency data path switching
• Random logic applications requiring differential inputs

Procurement Notes

Verify the specific suffix 'DWG' against current manufacturer documentation to confirm package type and RoHS compliance status. Check for obsolescence notices or recommended new design alternatives, as older ECL components may have limited production runs or be superseded by newer low-voltage variants.

Selection Notes

Select this component when differential signaling integrity is critical at frequencies exceeding typical TTL/CMOS limits. Ensure the system power supply aligns with the 3V to 5.5V operational window. Consider thermal management requirements given the continuous current draw inherent to ECL logic families during operation.

Part Context

This part belongs to the MC100LVEL family of low-voltage ECL devices designed for high-speed digital applications. It serves as a core switching element in communication systems and test equipment where signal fidelity and speed are prioritized over power consumption.

FAQ

What is the maximum operating frequency?

The device supports typical operation frequencies greater than 3 GHz.

How should unused differential inputs be handled?

Unused differential inputs can be connected to the internal V_BB pin to serve as a switch reference voltage or to re-bias AC-coupled inputs.
