MC10H161P

Overview

The MC10H161P is a binary to 1-8 decoder manufactured by onsemi in 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 (VEE = -5.2V ±5%). It features a typical propagation delay of 1.0 ns and power dissipation of 315 mW. The component is housed in a 16-pin PDIP 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 that the specific ordering suffix 'P' corresponds to the Plastic Dual In-Line Package (PDIP) as documented in the datasheet. Confirm RoHS compliance status, noting that lead-free variants typically carry a 'G' suffix. Ensure the procurement matches the obsolete or active status indicated in official manufacturer records.

Selection Notes

Select this component for applications requiring true parallel decoding without unequal path delays. It is suitable for systems utilizing MECL 10K compatible logic levels. Consider the 16-pin PDIP package for through-hole mounting requirements. Verify thermal equilibrium conditions during testing to ensure electrical parameters meet specifications.

Part Context

The MC10H161 belongs to the MECL 10H series of high-speed logic integrated circuits produced by onsemi. This series is designed for performance comparable to the legacy MECL 10K standard while offering modern packaging options. The part functions specifically as a binary decoder within this family.

Replacement Considerations

Consult the manufacturer's documentation for direct substitutes. Variants such as MC10H161FN (PLCC) or MC10H161L (CDIP) offer different package footprints but share identical logical functionality. Verify pin compatibility before substitution.
