MC10EL57DR2G

Overview

The MC10EL57DR2G is a fully differential 4:1 multiplexer from the onsemi 10EL series, packaged in a 16-lead SOIC. It operates with a constant power supply current of 24 mA across PECL and NECL modes. The device supports VCC ranges of 4.2 V to 5.7 V (VEE = 0 V) for PECL and VEE ranges of -4.2 V to -5.7 V (VCC = 0 V) for NECL. Propagation delays range from 350 ps to 580 ps depending on the signal path and temperature. It includes internal input pulldown resistors and provides multiple VBB outputs for single-ended or AC-coupled interfaces.

Feature Summary

• Configurable as either a 4:1 or 2:1 multiplexer by leaving the SEL1 line open.
• Provides internally generated VBB reference voltage outputs for single-ended operation and AC coupling rebiasing.
• Features internal input pulldown resistors that ensure Q outputs default to LOW when inputs are open.
• Includes ESD protection exceeding 1 kV Human Body Model and 100 V Machine Model standards.

Applications

• SONET/SDH clock and data multiplexing
• Fibre Channel and Gigabit Ethernet distribution
• Media tablet storage and peripheral multiplexing
• Wireless LAN card broadband access

Procurement Notes

Verify the specific ordering suffix DR2G corresponds to the 2500-unit tape and reel packaging configuration. Confirm the component status is active for new designs, noting that related variants like the MC100EL57DG may be discontinued. Ensure compliance with RoHS and lead-free requirements during procurement validation.

Selection Notes

Select this component for applications requiring differential ECL logic with flexible 4:1 or 2:1 selection capabilities. Consider the 10EL series characteristics for standard performance needs, while noting the 100EL series offers temperature compensation if required. Verify interface compatibility with PECL or NECL power supply configurations before integration.

Part Context

This device belongs to the 10EL family of high-speed ECL multiplexers manufactured by onsemi. It is designed for robust signal routing in high-frequency digital systems. The part utilizes a standard SOIC-16 surface mount package, facilitating integration into dense circuit board layouts requiring reliable differential signal processing.

Replacement Considerations

MC100EL57DG is listed as an alternative within the same product family.

FAQ

How does the device function as a 2:1 multiplexer?

By leaving the SEL1 line open, which pulls it low via internal resistors, the device selects between D0 and D1 based solely on the SEL0 input.

What is the purpose of the VBB pins?

Multiple VBB outputs provide an internally generated reference voltage used for single-ended input conditions or to rebias AC coupled inputs.
