(1) Propagation delay is measured on this circuit from VCC/2 on the input waveform to the 50% point on the output waveform.

NOTE:

Each MECL 10H series circuit has been designed to meet the dc specifications shown in the test table, after thermal equilibrium has been established. The

circuit is in a test socket or mounted on a printed circuit board and transverse air flow greater than 500 lfpm is maintained. Outputs are terminated through

a 50–ohm resistor to VCC – 2.0 Vdc.
