MC10H161FNR2

Overview

The MC10H161FNR2 is a binary to 1-8 decoder (low) from the MECL 10H series, designed for high-speed multiplexer/demultiplexer applications. It provides parallel decoding of a three-bit binary word to one of eight output lines, with outputs going low when selected and high otherwise. The device features voltage compensation and improved noise margins over operating voltage and temperature ranges. It operates within a supply voltage range of -4.9V to -5.46V and supports an operating temperature range of 0°C to +75°C.

Feature Summary

• Provides parallel decoding of a three-bit binary input to one of eight output lines
• Features voltage compensation for stable operation across varying conditions
• Offers improved noise margin of 150 mV over the operating voltage and temperature range
• Compatible with MECL 10K logic families

Applications

• High-speed multiplexer/demultiplexer systems
• Parallel decoding circuits requiring fast response times
• MECL 10K compatible digital logic designs

Procurement Notes

Verify the specific ordering suffix 'R2' corresponds to the tape and reel packaging configuration as documented in the official datasheet. Confirm that the Pb-free status aligns with project requirements by checking for the 'G' suffix if lead-free compliance is mandatory. Ensure compatibility with existing MECL 10H/10K infrastructure before procurement.

Selection Notes

Select this component for applications requiring fast parallel decoding with minimal propagation delay. Consider the MECL 10H series characteristics, including voltage compensation and noise immunity, when designing high-speed digital systems. Verify power dissipation requirements against thermal constraints, as typical power dissipation is specified at 315 mW.

Part Context

The MC10H161 belongs to the MECL 10H family of high-speed logic devices manufactured by onsemi. This family is known for its speed and compatibility with earlier MECL 10K standards. The FNR2 suffix indicates a specific package type and shipping configuration, distinguishing it from other variants like the DIP or SOEIAJ packages available in the same product line.

Replacement Considerations

Direct replacements include other MC10H161 variants such as MC10H161FN or MC10H161L, provided the package and pinout are compatible. Verify electrical specifications and environmental ratings match the original design requirements when substituting.
