MC10EL57D

Overview

The MC10EL57D is a fully differential 4:1 multiplexer from the onsemi 10EL series, operating in PECL or NECL modes. It supports VCC ranges of 4.2 V to 5.7 V (VEE = 0 V) and VEE ranges of -4.2 V to -5.7 V (VCC = 0 V). The device features internal input pulldown resistors of 75 kΩ and provides two VBB reference voltage outputs. Propagation delay from data inputs to outputs ranges from 350 ps to 580 ps depending on temperature, while select line propagation delay spans 440 ps to 710 ps. Input skew is specified at 100 ps, with output rise/fall times between 125 ps and 375 ps.

Feature Summary

• Configurable as either a 4:1 or 2:1 multiplexer by leaving the SEL1 line open.
• Includes multiple VBB outputs for single-ended operation and AC coupled interface rebiasing.
• Features internal input pulldown resistors on all inputs to simplify circuit design.
• Q outputs default to LOW state when inputs are left open or connected to VEE.

Applications

• High-speed data routing in communication systems
• Signal selection in differential logic circuits
• Clock distribution networks requiring low skew

Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-16 package configuration. Confirm RoHS compliance status and lead-free marking requirements for your assembly process. Check current availability as some variants may be discontinued or subject to change. Ensure thermal management meets the junction-to-ambient resistance specifications for your enclosure design.

Selection Notes

Select this component for applications requiring fully differential ECL signaling with configurable mux ratios. Consider the 100EL variant if temperature compensation is required for wider thermal stability. Evaluate power supply constraints against the specified PECL or NECL operating ranges. Verify that the SOIC-16 package dimensions fit your PCB layout constraints.

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 operates as a 2:1 multiplexer selecting between D0 and D1 based on the SEL0 input.

What is the purpose of the VBB pins?

The VBB pins provide an internally generated reference voltage used for single-ended input conditions or to rebias AC coupled inputs. They must be decoupled with a 0.01 μF capacitor when used.
