MC100E457FNG

Overview

The MC100E457FNG is a 3-bit differential 2:1 multiplexer from the 100 Series, designed for low skew clock or data path applications. It features fully differential data paths with separate and common select inputs. 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). Key electrical parameters include a maximum propagation delay of 700 ps, a maximum toggle frequency of 1.1 GHz, and internal input clamp structures that force outputs LOW during open input conditions.

Feature Summary

• Fully differential data path architecture minimizes signal skew for high-speed clock distribution
• Integrated temperature compensation within the 100 Series ensures stable performance across operating temperatures
• Internal input clamp structures prevent undefined states by forcing outputs LOW when differential inputs are left open
• Multiple VBB pins facilitate AC coupling and provide reference voltage switching capabilities

Applications

• Multiplexing low skew clock signals in demanding system architectures
• High-frequency data path routing requiring differential signal integrity
• Random logic applications utilizing separate or common select configurations

Procurement Notes

Verify component authenticity through authorized channels as counterfeit risks exist. Confirm RoHS compliance status and lead-free packaging specifications against current manufacturing standards. Check for specific moisture sensitivity level requirements during storage and handling. Ensure ordering suffixes match exact package and shipping format needs. Validate datasheet revisions to ensure compatibility with design specifications.

Selection Notes

Select this component for designs requiring differential ECL multiplexing with minimal skew. The 100 Series variant provides necessary temperature compensation compared to standard series options. Verify power supply configuration matches either PECL or NECL operational modes. Ensure PCB layout accommodates PLCC-28 surface mount package dimensions. Consider thermal resistance characteristics for adequate heat dissipation in enclosed environments.

Part Context

This device belongs to the MC100E457 family of triple differential 2:1 multiplexers manufactured by onsemi. It utilizes a 28-lead PLCC package suitable for surface mount technology. The component operates within the 5V ECL logic family, providing high-speed switching capabilities essential for modern digital communication systems and high-performance computing applications.

Replacement Considerations

MC10E457FNR serves as a functional substitute lacking temperature compensation. MC100E457FNR offers identical electrical performance in tape and reel packaging instead of tubes. Verify pinout compatibility and power supply requirements before substitution. Confirm package dimensions match existing board footprints to avoid mechanical interference.
