The MC10H109 is a dual 4–5–input OR/NOR gate. This MECL 10H part is a functional/pinout duplication of the standard MECL 10K family part, with 100% improvement in propagation delay, and no increase in power–supply current.

• Propagation Delay, 1.0 ns Typical
• Power Dissipation 35 mW/Gate Typical (same as MECL 10K)
• Improved Noise Margin 150 mV (Over Operating Voltage and Temperature Range)
• Voltage Compensated
• MECL 10K–Compatible
