The MC10H130 is a MECL 10H part which is a functional/pinout duplication of the standard MECL 10K family part, with 100% improvement in clock speed and propagation delay and no increase in power–supply current.
   
• Propagation Delay, 1.0 ns Typical
• Power Dissipation, 155 mW Typical
• Improved Noise Margin 150 mV (Over Operating Voltage and
    Temperature Range)
• Voltage Compensated
• MECL 10K–Compatible
