MC100EP56MNTXG

Overview

The MC100EP56MNTXG is a dual, fully differential 2:1 multiplexer from the onsemi 100 Series ECL logic family. It features a propagation delay of 360 ps typical and supports maximum frequencies exceeding 3 GHz. The device operates in PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) or NECL mode with VEE ranging from -3.0 V to -5.5 V (VCC = 0 V). It includes temperature compensation, separate and common select inputs, and an internally generated VBB output reference voltage. The component is housed in a QFN-20 package.

Feature Summary

• Dual fully differential data path designed for low skew clock or skew-sensitive signal multiplexing
• Temperature compensated circuitry within the 100 Series architecture
• Internally generated VBB pin available as a switching reference voltage or AC coupling rebias source
• Outputs default to LOW state when inputs are open or at VEE

Applications

• Multiplexing low skew clock signals
• Skew-sensitive signal routing applications
• Random logic applications requiring individual or common select inputs

Procurement Notes

Verify the specific suffix 'MNTXG' against official documentation, as datasheets list 'MNG' for the QFN-20 tube variant. Confirm current status, as the MC100EP56 series is marked discontinued and not recommended for new designs. Ensure compatibility with required packaging formats and lead-free specifications.

Selection Notes

Select this component for high-speed differential signal routing where minimal skew is critical. The 100 Series offers temperature compensation compared to the standard 10EP series. Verify power supply requirements align with either PECL or NECL configurations. Consider the discontinued status when planning long-term production cycles.

Part Context

FAQ

What is the function of the VBB pins?

The VBB pins provide an internally generated voltage supply used as a switching reference voltage for unused differential inputs or to rebias AC coupled inputs.

How does the device handle open inputs?

The device features an open input default state where the Q outputs will default to LOW if inputs are left open or are at VEE.
