MC10EP56DTG

Overview

The MC10EP56DTG is a dual, fully differential 2:1 multiplexer from the 10EP series designed for low skew clock or skew-sensitive signal routing. It operates in PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) and NECL mode with VEE from -3.0 V to -5.5 V (VCC = 0 V). The device features typical propagation delays of 360 ps and supports maximum frequencies exceeding 3 GHz. It includes separate and common select inputs, internal VBB outputs for reference biasing, and safety clamps on inputs.

Feature Summary

• Dual fully differential data path optimized for low skew applications
• Supports both PECL and NECL operating voltage ranges
• Includes individual and common select input configurations
• Provides internally generated VBB output reference voltage

Applications

• Multiplexing low skew clock signals
• Routing skew-sensitive high-speed data paths
• Random logic applications requiring differential switching

Procurement Notes

Verify that the ordering suffix DTG corresponds to the TSSOP-20 package configuration. Confirm RoHS compliance status as indicated by the G suffix. Ensure power supply connections are properly decoupled according to datasheet requirements for stable operation.

Selection Notes

Select this component when differential signal integrity is critical for clock distribution or high-speed data routing. Consider the 100EP variant if temperature compensation is required for the application environment. Verify that the 20-pin TSSOP footprint fits the PCB layout constraints.

Part Context

This part belongs to the MC10/100EP56 family of ECL multiplexers manufactured by onsemi. It is distinct from the 100EP series which adds temperature compensation. The device utilizes a 20-lead TSSOP package and contains 140 transistors within its architecture.

Replacement Considerations

MC100EP56DTG is a parameter-equivalent alternative within the same package offering temperature compensation.
