
Delay time (td): the response time from OUTPUT1 rises to 50% of amplitude to LINE1+ decreases to
90% of amplitude

Falling time (tf): the response time for LINE1+ to decrease from 90% of the amplitude to 10%

Storage time (ts): the response time from OUTPUT1 decreases to 50% of amplitude to LINE1+ rises
to 10% of amplitude

Rising time (tr): the response time for LINE1+ to rise from 10% of the amplitude to 90%
