MC10H158M

Overview

The MC10H158M is a quad two-input multiplexer from the MECL 10H family, featuring common input select. It provides non-inverting logic with four independent channels. The device operates within a temperature range of 0°C to +75°C and dissipates approximately 197 mW typical power. Propagation delay is typically 1.5 ns for data paths and 2.9 ns for select lines at 25°C. It utilizes an SOEIAJ-16 package.

Feature Summary

• Provides four independent two-channel multiplexing functions controlled by a single select line
• Features voltage compensated design ensuring improved noise margins across operating conditions
• Offers functional and pinout compatibility with the standard MECL 10K family

Applications

• High-speed digital signal routing in communication systems
• Data selection circuits requiring low propagation delay
• MECL 10K compatible logic system upgrades

Procurement Notes

Verify the specific suffix 'M' corresponds to the SOEIAJ-16 package configuration required for your PCB layout. Confirm whether Pb-free variants (suffix G) are needed for compliance. Ensure supply chain sources provide original manufacturer documentation to validate authenticity and revision status.

Selection Notes

Select this component when MECL 10H speed improvements over the 10K family are required without increasing power consumption. Verify that the -5.2 V power supply requirement aligns with your system architecture. Consider the SOEIAJ-16 footprint constraints during schematic capture.

Part Context

This part belongs to the MECL 10H series, designed as a high-speed replacement for legacy MECL 10K components. It maintains identical pinouts while delivering faster switching speeds. The MC10H158 specifically addresses applications needing multiple parallel data selection paths.

Replacement Considerations

MC10H158P (PDIP-16), MC10H158L (CDIP-16), MC10H158FN (PLCC-20). These variants share identical electrical characteristics but differ in physical package dimensions.
