The MC10H101 is a quad 2input OR/NOR gate with one input from each gate common to pin 12. This MECL 10H part is a functional/pinout duplication of the standard MECL 10K family part, with 100% improvement in propagation delay, and no increases in powersupply current. Propagation Delay, 1.0 ns Typical Power Dissipation 25 mW/Gate (same as MECL 10K) Improved Noise Margin 150 mV (Over Operating Voltage and Temperature Range)
