MC10H161M

Overview

The MC10H161M is a binary to 1-8 decoder manufactured by onsemi, belonging to the MECL 10H series. It provides parallel decoding of a three-bit binary word to one of eight lines, with outputs going low when selected and high otherwise. The device operates on dual power supplies ranging from -4.94V to -5.46V, typically centered at -5.2V. It features a typical propagation delay of 1.0 ns and power dissipation of 315 mW. The component is housed in a 16-SOEIAJ package.

Feature Summary

• True parallel decoding architecture eliminates unequal parallel path delays found in other designs.
• Compatible with MECL 10K logic standards for system integration.
• Voltage compensated design ensures improved noise margin over operating voltage and temperature ranges.

Applications

• High-speed multiplexer applications
• Demultiplexer applications
• Parallel decoding of three-bit binary words

Procurement Notes

Verify the specific suffix 'M' corresponds to the SOEIAJ-16 package configuration as listed in the ordering information table. Confirm RoHS compliance status if lead-free requirements are necessary, noting that the base part number may differ from the Pb-Free variant (MC10H161MG). Check current product status as older revisions may be obsolete.

Selection Notes

Select this component for applications requiring fast parallel decoding within the MECL 10H ecosystem. Ensure the design supports dual power supply rails between -4.94V and -5.46V. Consider the 16-SOEIAJ package dimensions for PCB layout constraints. Verify thermal management capabilities given the typical power dissipation of 315 mW.

Part Context

This decoder is part of the MC10H161 family, which includes variants like MC10H161FN (PLCC) and MC10H161P (PDIP). All variants share the same logical function but differ in packaging and shipping configurations. The MC10H161M specifically utilizes the SOEIAJ-16 case outline.

Replacement Considerations

Direct substitutes include other MC10H161 variants such as MC10H161FN or MC10H161P if package compatibility allows. For lead-free requirements, consider MC10H161MG. No functional equivalents outside the MECL 10H/10K families are documented in the source material.
