MC100EP56DWR2

Overview

The MC100EP56DWR2 is a dual, fully differential 2:1 multiplexer from the 100 Series. It features typical propagation delays of 360 ps and a maximum frequency exceeding 3 GHz. Operating in PECL mode requires VCC between 3.0 V and 5.5 V with VEE at 0 V; NECL mode uses VCC at 0 V and VEE between -3.0 V and -5.5 V. The device includes temperature compensation, internal VBB outputs, and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Dual fully differential data path designed for low skew clock or skew-sensitive signal multiplexing
• Temperature compensated circuitry characteristic of the 100 Series
• Internal VBB output reference voltage available for single-ended input biasing or AC coupling rebiasing
• Separate and common select inputs support both data path and random logic applications

Applications

• Multiplexing low skew clock signals
• Processing skew-sensitive signals
• Random logic applications requiring differential switching

Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 package configuration required for your layout. Confirm that the 'R2' designation aligns with the intended tape and reel packaging specifications. Ensure the component meets RoHS compliance standards for your manufacturing process. Validate that the operating voltage ranges match your system's power supply architecture before finalizing procurement.

Selection Notes

Select this component when differential signal integrity and minimal skew are critical requirements. The 100 Series offers temperature compensation compared to the standard 10EP variant. Consider the SOIC-20 package if space constraints allow for wider pitch connections. Verify compatibility with PECL or NECL logic levels based on your system's power supply configuration.

Part Context

This part belongs to the MC10/100EP56 family of high-speed ECL multiplexers. The 100 Series distinguishes itself through integrated temperature compensation, enhancing performance stability across varying thermal conditions. The device integrates two independent 2:1 multiplexers into a single compact package, optimizing board space for complex signal routing architectures.

Replacement Considerations

MC10EP56 variants serve as functional equivalents but lack the temperature compensation found in the 100 Series. MC100EP56DTG and MC100EP56DTR2G offer identical electrical characteristics in TSSOP-20 packages. Direct pin-to-pin substitution is possible provided the package footprint matches the design constraints.
