The MC10H124 is a quad translator for interfacing data and control signals between a saturated logic section and the MECL section of digital systems. The 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, 1.5 ns Typical
• Improved Noise Margin 150 mV (Over Operating Voltage and
    Temperature Range)
• Voltage Compensated
• MECL 10K–Compatible
