The MC10H186 is a hex D type flipflop with common reset and clock lines. This MECL 10H part is a functional/pinout duplication of the standard MECL 10K family part, with 100 % i mprovement in clock toggle frequency and propagation delay and no increase in powersupply current. Propagation Delay, 1.7 ns Typical Power Dissipation, 460 mW Typical Improved Noise Margin 150 mV (Over Operating Voltage and Temperature Range)
