MC10H159M

Overview

The MC10H159M is a quad 2-input multiplexer with enable, belonging to the MECL 10H family. It offers functional and pinout compatibility with the standard MECL 10K series while providing a 100% improvement in propagation delay without increasing power-supply current. The device operates with voltage-compensated inputs and features improved noise margins of 150 mV over the operating voltage and temperature range. It utilizes a SOEIAJ-16 package.

Feature Summary

• Provides quad 2-input multiplexing functionality with common enable and select inputs.
• Delivers significantly faster propagation delay compared to the legacy MECL 10K family.
• Maintains identical pinout and functionality for seamless integration into existing designs.
• Features voltage-compensated inputs and enhanced noise margin stability.

Applications

• High-speed data routing in MECL-based logic systems
• Signal selection in differential communication interfaces
• Multiplexing applications requiring low propagation delay

Procurement Notes

Verify the specific ordering suffix to confirm the package type and lead-free status. The 'M' suffix indicates the SOEIAJ-16 package. Confirm availability of Pb-Free variants if required by environmental regulations. Ensure supply chain documentation matches the exact part number MC10H159M to guarantee correct package dimensions and marking specifications.

Selection Notes

Select this component when upgrading from MECL 10K devices to achieve higher speed without redesigning the PCB layout. It is suitable for applications requiring quad multiplexing with inverted outputs. Verify that the system power supply aligns with the specified VEE range of -5.2 V ±5%. Consider thermal management requirements based on the typical power dissipation of 218 mW.

Part Context

This component is part of the MECL 10H high-speed logic family produced by onsemi. It serves as a direct replacement for the MECL 10K equivalent, offering performance improvements while maintaining backward compatibility. The family is designed for applications demanding fast switching speeds and reliable operation in negative voltage logic environments.

Replacement Considerations

The MC10H159M is functionally and pinout compatible with the standard MECL 10K family parts. No external resistor changes are typically required for basic substitution, but verify signal integrity and termination networks due to the reduced propagation delay.
