MC100EL58D

Overview

The MC100EL58D is a 2:1 multiplexer from the 100 Series, functionally equivalent to the E158 device but with significantly faster propagation delays and output transition times. It features temperature compensation for stable performance across operating conditions. The device supports PECL mode (VCC = 4.2 V to 5.7 V, VEE = 0 V) and NECL mode (VCC = 0 V, VEE = −4.2 V to −5.7 V). Propagation delay is typically 230 ps. Internal input pulldown resistors are present on Da, Db, and SEL inputs.

Feature Summary

• Temperature compensated design ensures consistent AC performance across varying environmental conditions.
• Internal input pulldown resistors on data and select lines simplify circuit design and improve signal stability.
• Supports both PECL and NECL logic families with wide supply voltage ranges for flexible system integration.

Applications

• High-speed data acquisition systems requiring low latency signal selection
• Telecommunications equipment utilizing ECL logic standards
• Test and measurement instruments demanding precise timing control

Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-8 package configuration. Confirm RoHS compliance status as some variants may differ. Check current availability status as older revisions or packages might be discontinued. Ensure thermal management meets junction-to-ambient requirements for the selected mounting method.

Selection Notes

Choose this component when temperature stability is critical for high-speed ECL applications. The 100 Series offers superior performance over the standard 10 Series due to integrated temperature compensation. Verify that the required propagation delay of 230 ps meets system timing constraints. Ensure power supply rails align with PECL or NECL specifications.

Part Context

This device belongs to the MC10EL/100EL series of high-performance ECL multiplexers manufactured by onsemi. It serves as an upgraded alternative to legacy E158 devices, providing enhanced speed and reliability. The product line includes various package options including SOIC and TSSOP configurations to suit different PCB layout requirements.

Replacement Considerations

MC10EL58D is functionally equivalent to the E158 device but offers improved performance metrics. Designers replacing older components should verify pin compatibility and ensure that the new device's temperature compensation does not conflict with existing thermal designs.
