100LVEL11M

Overview

The Fairchild Semiconductor 100LVEL11M is a differential ECL fanout buffer designed for high-speed clock distribution. It features a single circuit with a 1:2 input-to-output ratio, providing two differential outputs from one differential input. The device operates within a supply voltage range of 3V to 3.8V and supports an operating temperature range of -40°C to +85°C. Packaged in an 8-SOIC surface-mount case (0.154" width), it is part of the 100LVEL series intended for low-voltage ECL applications requiring signal buffering and distribution.

Feature Summary

• Differential ECL input and output configuration
• 1:2 fanout ratio for clock distribution
• Operates on 3V to 3.8V supply voltage
• Available in 8-SOIC surface-mount package

Applications

• High-speed clock distribution networks
• ECL-based system timing architectures
• Signal buffering in differential data paths

Procurement Notes

Verify the specific datasheet for the 100LVEL11M variant to confirm propagation delay and skew specifications, as these are critical for timing-sensitive designs. Ensure the 8-SOIC footprint matches the target PCB layout. Confirm RoHS compliance status if required by assembly standards.

Selection Notes

Select this component when a differential ECL buffer with a 1:2 split is required. Compare against other 100LVEL series parts for pin compatibility and electrical performance differences. Verify that the 3V-3.8V supply range aligns with the system power rails and that the -40°C to 85°C temperature range meets environmental requirements.

Part Context

This part belongs to the 100LVEL series of low-voltage ECL logic devices. It serves as a specialized buffer within Fairchild's portfolio for managing differential signals in high-speed digital systems, distinct from standard TTL or CMOS buffers.
