MC10H174FN

Overview

The MC10H174FN is a dual 4-to-1 multiplexer from the MECL 10H series, manufactured by onsemi. It operates with a negative supply voltage ranging from -4.94 V to -5.46 V and features a 20-pin PLCC package. The device provides two independent multiplexing channels with differential outputs. Typical propagation delay is 1.5 ns, with typical power dissipation of 305 mW at 25°C. It maintains compatibility with standard MECL 10K logic levels while offering improved noise margins.

Feature Summary

• Dual 4-to-1 multiplexing functionality with differential outputs
• Compatible with MECL 10K logic standards
