MC10E457FN

Overview

The MC10E457FN is a 5 V ECL triple differential 2:1 multiplexer manufactured by onsemi. It features a fully differential data path suitable for low skew clock signals, with high frequency outputs providing over 1.0 GHz bandwidth. The device supports PECL mode (VCC = 4.2 V to 5.7 V, VEE = 0 V) and NECL mode (VCC = 0 V, VEE = -4.2 V to -5.7 V). It includes separate and common select inputs, internal input clamp structures, and VBB reference voltage pins. Operating temperature range is -40°C to +85°C.

Feature Summary

• Fully differential data path designed for multiplexing low skew clock or other skew sensitive signals
• High frequency outputs provide greater than 1.0 GHz bandwidth for demanding system clocks
• Internal clamp structures force Q output to LOW state in open input conditions
• Separate and common select inputs support both data path and random logic applications

Applications

• Multiplexing low skew clock signals
• Multiplexing skew sensitive signals
• Data path applications
• Random logic applications

Procurement Notes

Verify the specific suffix 'FN' corresponds to the PLCC-28 package configuration as documented. Confirm RoHS compliance status against current manufacturer announcements, as historical data indicates potential variations. Ensure supply chain sources are authorized distributors to guarantee component authenticity and traceability.

Selection Notes

Select this component when differential signal integrity is critical due to its fully differential architecture. Consider the >1.0 GHz bandwidth requirement for high-speed system clocks. Verify compatibility with PECL or NECL power supply configurations based on the target circuit design requirements.

Part Context

This part belongs to the MC10E/100E series of 5 V ECL logic devices from onsemi. It is functionally related to the MC100E457, which offers temperature compensation. Both variants share the same pinout and basic functionality but may differ in specific electrical characteristics across temperature ranges.

Replacement Considerations

MC100E457FNR2G is a documented alternative within the same family offering temperature compensation.
