MC100EL58DR2

Overview

The MC100EL58DR2 is a high-performance 5.0V ECL 2:1 multiplexer manufactured by onsemi. It functions as a differential data selector with two data inputs and one select input, providing complementary outputs. The device belongs to the 100 series, which incorporates temperature compensation to maintain stable performance across varying thermal conditions. It supports wide supply voltage ranges for both PECL and NECL configurations, ensuring compatibility with diverse system power architectures while delivering fast signal switching capabilities.

Feature Summary

• Temperature-compensated design ensures consistent electrical performance across operating temperature variations
• Supports flexible power integration through wide voltage range compatibility for both PECL and NECL logic families
• Internal pull-down resistors on data and select inputs simplify circuit design and improve signal stability

Applications

• High-speed data routing in communication systems
• Signal selection in high-frequency processing circuits
• Differential logic interfacing in telecommunications equipment

Procurement Notes

Verify the specific suffix DR2 indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status for environmental requirements. Ensure the selected variant matches the required temperature compensation features of the 100 series. Cross-reference the datasheet revision to confirm pinout and electrical specifications align with current design standards before finalizing procurement.

Selection Notes

Select this component when temperature stability is critical for ECL logic applications. The 100 series offers superior thermal consistency compared to standard EL variants. Verify that the system operates within the specified 5.0V ECL voltage windows. Consider the internal pull-down features if minimizing external components is a priority for the board layout.

Part Context

This part is part of onsemi's MC10EL/100EL logic family, designed for high-speed differential signaling. The 100 series designation specifically denotes devices with integrated temperature compensation, distinguishing them from the standard MC10EL counterparts. It serves as a direct functional replacement for legacy ECL multiplexers requiring enhanced thermal stability.

Replacement Considerations

The MC10EL58 is a compatible alternative but lacks the temperature compensation found in the 100 series. Verify if the application requires the specific thermal stability provided by the 100 series or if the standard EL version suffices.
