MC100EP57MNG

Overview

The MC100EP57MNG is a fully differential 4:1 multiplexer from the onsemi 100 Series, housed in a QFN-20 package. It operates within a PECL voltage range of VCC = 3.0 V to 5.5 V (VEE = 0 V) or an NECL range of VCC = 0 V and VEE = -3.0 V to -5.5 V. The device features typical propagation delays of 375 ps and supports maximum frequencies exceeding 2 GHz. It includes temperature compensation, internal input pulldown resistors, and safety clamps.

Feature Summary

• Fully differential architecture designed for low skew applications such as clock distribution
• Configurable as either a 4:1 or 2:1 multiplexer by leaving the SEL1 line open
• Includes multiple VBB outputs for use as switching reference voltages or AC coupling rebiasing
• Features open input default states with safety clamps to prevent undefined output conditions

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance and Pb-Free status. Check datasheet revision history for updates. Ensure proper thermal management via the exposed pad connection to VEE. Validate operating conditions against specified electrical limits before integration.

Selection Notes

Select this component for high-frequency differential signal routing where minimal skew is critical. The 100 Series offers temperature compensation for stable operation across varying environments. Consider the QFN-20 package for compact surface-mount designs requiring efficient heat dissipation through the exposed pad.

Part Context

Part of the MC10/100EP57 family of ECL multiplexers. The 100 Series distinguishes itself with temperature-compensated characteristics compared to the standard 10 Series. Available in TSSOP-20 and QFN-20 packages, providing flexibility for different PCB layout requirements while maintaining identical functional specifications.

Replacement Considerations

MC10EP57MNG serves as a direct functional substitute within the same family. Verify package compatibility when transitioning between MC10 and MC100 series variants. Consult official documentation for any pinout differences or specific ordering suffix variations.
