MC10171P

Overview

The MC10171P is a dual binary to 1-to-4 decoder manufactured by onsemi, belonging to the MECL 10K logic family. It features two independent decoders that convert binary coded inputs into four selected outputs which are active low. The device operates with a typical propagation delay of 2 ns and power dissipation of 325 mW. It provides improved noise margins of 150 mV over the operating voltage and temperature range. The component utilizes voltage compensation for stable performance and is housed in a standard 16-pin DIP package.

Feature Summary

• Dual binary to 1-to-4 decoding capability with selected outputs held low
• High-speed operation with typical 2 ns propagation delay
• Enhanced noise margin of 150 mV across operating conditions
• Voltage compensated design ensuring stability within the MECL 10K family

Applications

• High-speed digital data routing systems
• Address decoding in memory architectures
• Control signal distribution in telecommunications equipment
• Logic level translation interfaces compatible with MECL standards

Procurement Notes

Verify the specific suffix 'P' indicates the plastic DIP package configuration as documented. Confirm RoHS compliance status, as older MECL 10K variants may not meet current environmental directives. Check for obsolescence notices or PCN documents from onsemi regarding this specific part number before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring dual independent decoding functions within the MECL 10K ecosystem. Ensure the system power supply aligns with the negative voltage requirements typical of ECL families. Verify that the 16-pin DIP footprint matches the PCB layout constraints and thermal management requirements for the specified power dissipation levels.

Part Context

This decoder is part of the broader MC10H17x series from onsemi, designed for high-speed digital applications. It shares functional similarities with other decoders in the line but offers specific output polarity characteristics. The device supports legacy MECL 10K designs while providing improved noise immunity compared to earlier generations.

Replacement Considerations

Direct substitutes include MC10H171FN and MC10H171FNG from onsemi, which offer identical functionality in surface-mount packages. Cross-reference with other MECL 10K compatible decoders if pin-out compatibility is required.
