100EL11M

Overview

The Fairchild Semiconductor 100EL11M is a single differential ECL fanout buffer configured for a 1:2 output ratio. It operates within a supply voltage range of 4.2 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. The device is housed in an 8-SOIC package with a width of 3.90 mm, designed for surface-mount installation. As part of the 100EL series, it functions as a clock buffer and distribution component, providing differential input and output capabilities suitable for high-speed logic applications.

Feature Summary

• Single circuit differential ECL fanout buffer with 1:2 input-to-output ratio
• Operates on a 4.2 V to 5.5 V power supply
• Available in an 8-SOIC (0.154" width) surface-mount package

Applications

• Clock signal distribution in ECL-based systems
• Differential fanout buffering for high-speed logic circuits
• Signal integrity maintenance in telecommunications infrastructure

Procurement Notes

Verify the manufacturer designation, as this component is historically associated with Fairchild Semiconductor but may be produced by onsemi following industry acquisitions. Confirm the specific ordering suffix matches the 8-SOIC tube packaging requirement. Ensure the procurement source provides valid RoHS compliance documentation consistent with the 100EL series specifications.

Selection Notes

Select this component when a differential ECL fanout buffer with a 1:2 ratio is required. The 4.2 V to 5.5 V supply range must align with the system's power architecture. The 8-SOIC package is suitable for standard surface-mount assembly processes. Verify that the application does not require higher frequency performance metrics than those defined for the base 100EL series.

Part Context

This component belongs to the 100EL series of ECL logic devices. It serves as a fundamental building block for clock distribution networks requiring differential signaling. The 8-SOIC package offers a compact footprint for surface-mount technology implementations in industrial and communication equipment.

Replacement Considerations

Cross-reference with MC100EL11 variants from onsemi or other manufacturers offering identical 1:2 differential ECL fanout buffers in 8-SOIC packages. Ensure pin compatibility and electrical parameters match the original design requirements.
