MC10EP56DTR2G

Overview

The MC10EP56DTR2G is a dual, fully differential 2:1 multiplexer from the onsemi 10EP series. It operates in PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) and NECL mode with VEE ranging from -3.0 V to -5.5 V (VCC = 0 V). The device features typical propagation delays of 360 ps and a maximum frequency exceeding 3 GHz. It includes separate and common select inputs, open input default states, safety clamps, and internally generated VBB output reference voltage pins.

Feature Summary

• Dual fully differential data path designed for low skew clock or skew-sensitive signal multiplexing
• Provides both individual and common select inputs for flexible data path and random logic applications
• Includes internally generated VBB pins that serve as switching reference voltages or AC coupling re-bias points
• Features open input default states and safety clamps to ensure Q outputs default LOW when inputs are open or at VEE

Applications

• Multiplexing low skew clock signals
• Multiplexing other skew sensitive signals
• Data path applications requiring differential signaling
• Random logic applications utilizing separate or common select inputs

Procurement Notes

Verify the specific package suffix matches the required form factor; this part number corresponds to the TSSOP-20 tape and reel configuration. Confirm RoHS compliance and Pb-free status by checking the marking diagram or official documentation. Ensure power supply connections for all VCC and VEE pins are established externally to guarantee proper operation. Validate thermal requirements against the junction-to-ambient resistance values provided in the datasheet for the specific airflow conditions.

Selection Notes

Select this component when differential signaling is required to minimize skew in high-speed applications. The 10EP series offers standard performance, whereas the 100 series provides temperature compensation if environmental stability is critical. Consider the availability of separate versus common select inputs based on control logic complexity. Verify that the operating voltage range aligns with the system's PECL or NECL power rails.

Part Context

This device belongs to the MC10/100EP56 family of dual differential 2:1 multiplexers manufactured by onsemi. It is available in multiple packages including SOIC-20, TSSOP-20, and QFN-20. The DTR2G suffix specifically denotes the TSSOP-20 package supplied in a tape and reel format. The 10EP variant represents the standard performance level within the product line.

Replacement Considerations

MC100EP56DTR2G is a parameter-equivalent alternative within the same family, offering temperature compensation.
