MC100EP56DWG

Overview

The MC100EP56DWG is a dual differential 2:1 multiplexer from the onsemi 100EP series, designed for low skew clock or other skew-sensitive signal multiplexing applications. It operates within a supply voltage range of 3 V to 5.5 V and features a propagation delay of 0.47 ns at 3 V to 5.5 V. The device is housed in a QFN-20 package and supports surface mount installation. It functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Designed specifically for low skew clock or other skew-sensitive signal multiplexing applications
• Features differential data paths with separate and common select inputs for data path and random logic needs
• Includes internal generated power voltage (VBB) pins for switch reference voltage and AC-coupled input re-biasing
• Provides input open default states and safety clamps to ensure output stability and protection against overvoltage

Applications

• Low skew clock signal multiplexing
• Skew-sensitive signal routing
• High-speed data path switching
• Random logic applications requiring differential inputs

Procurement Notes

Verify the specific suffix 'DWG' corresponds to the SOIC-20 package variant when sourcing, as the MNG suffix denotes QFN-20. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design accounts for the required 0.01μF decoupling capacitors for VBB and VCC pins. Validate that the selected package aligns with PCB footprint requirements for thermal management and mechanical stability.

Selection Notes

Select this component for designs requiring differential ECL multiplexing with minimal propagation delay. The 100EP series offers temperature compensation, enhancing reliability across varying environmental conditions. Consider the available package options, such as SOIC-20 or QFN-20, based on space constraints and thermal performance needs. Ensure the application benefits from the device's ability to handle skew-sensitive signals effectively.

Part Context

The MC100EP56DWG belongs to the MC100EP56 family of high-performance multiplexers. This family is characterized by its use in demanding high-speed digital systems where signal integrity is critical. The device complements other logic ICs in the 100EP series, providing specialized functionality for signal routing and selection in complex electronic architectures.

FAQ

How should unused differential inputs be handled?

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

What is the function of the VBB pin?

The VBB pin provides an internally generated power voltage available only to the device, used for setting switch reference levels and biasing AC-coupled inputs.
