MC100EL57DG

Overview

The MC100EL57DG is a high-speed, fully differential 4:1 multiplexer from the onsemi MC100E logic series. It operates within a supply voltage range of -4.2 V to -5.7 V for VEE and 0 V to 5.7 V for VCC. The device features a propagation delay of 0.56 ns at 5 V and functions in both PECL and NECL modes. Packaged in a 16-pin SOIC (NB) surface-mount format, it supports an operating temperature range from -40 °C to +85 °C. This component integrates internal input pull-down resistors and provides multiple VBB outputs for single-ended or AC-coupled interface flexibility.

Feature Summary

• Fully differential architecture supporting flexible configuration as either a 4:1 or 2:1 multiplexer by manipulating select line states.
• Integrated VBB output pins generate internal reference voltages suitable for single-ended inputs or AC-coupled signal re-biasing.
• Built-in input clamping circuits ensure stable low-level default outputs when inputs are open or pulled to VEE.
• Temperature-compensated design maintains consistent performance across the specified industrial temperature range.

Applications

• High-speed data routing in communication systems requiring differential signal integrity.
• Clock distribution networks where low skew and precise timing selection are critical.
• Test and measurement equipment utilizing ECL-compatible logic families for rapid signal processing.

Procurement Notes

Verify current availability status as this specific part number may be subject to end-of-life transitions or obsolescence notices. Confirm that the SOIC-16 NB package matches your PCB footprint requirements. Ensure power supply rails strictly adhere to the specified PECL or NECL voltage ranges to prevent device malfunction. Check for RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when designing with 5V ECL logic families requiring differential signaling capabilities. It is appropriate for applications needing fast switching speeds with minimal propagation delay. Consider the MC10EL57 variant if tape-and-reel packaging is preferred over tubes. Ensure the system can accommodate the required dual-supply voltage configuration typical of ECL technology.

Part Context

This device belongs to the MC100E series, which represents advanced emitter-coupled logic optimized for high-frequency operations. The MC100 prefix typically indicates temperature compensation compared to the standard MC10 series. It serves as a functional equivalent to legacy ECL mux devices but offers improved speed and reliability characteristics suitable for modern high-performance digital designs.

Replacement Considerations

MC10EL57DG is a compatible alternative within the same family offering identical logical functionality. MC100EL57DR2G provides the same core specifications but utilizes a tape-and-reel packaging format instead of tubes. Verify pinout compatibility before substituting these variants in existing designs.
