100LVEL11MX

Overview

The Fairchild Semiconductor 100LVEL11MX is a single-channel clock buffer within the 100LVEL series, designed for 3.3V ECL applications. It functions as a differential fanout buffer with a 1:2 distribution ratio, converting one differential input to two differential outputs. The device operates on a supply voltage ranging from 3V to 3.8V and supports surface-mount installation in an 8-SOIC package (0.154 inch width). It is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Differential 1:2 Fanout Buffer topology
• 3.3V ECL compatible input and output signals
• Supply voltage range of 3V to 3.8V
• 8-SOIC surface-mount package

Applications

• Clock distribution networks requiring signal buffering
• ECL-based logic systems
• High-speed digital circuit interfaces

Procurement Notes

Verify the manufacturer designation, as this part number is associated with Fairchild Semiconductor but shares specifications with onsemi equivalents. Confirm the specific ordering suffix 'MX' corresponds to the bulk packaging format and SOIC-8 dimensions. Ensure compatibility with existing 3.3V ECL power rails before integration.

Selection Notes

Select this component when a low-power, high-speed differential buffer is required for 3.3V ECL environments. The 1:2 ratio suits simple fanout needs without inversion. Verify that the 8-SOIC footprint fits the PCB layout constraints and that the -40°C to +85°C industrial temperature range meets the system's thermal requirements.

Part Context

This device belongs to the 100LVEL family of low-voltage ECL components. It serves as a fundamental building block for clock tree structures, providing signal integrity maintenance between source generators and downstream loads in high-frequency digital designs.

Replacement Considerations

The MC100LVEL11DR2G from onsemi offers identical electrical characteristics and pinout in an SOIC-8 package. Cross-reference datasheets to confirm mechanical tolerance alignment for the 8-SOIC case before substitution.
