Opto-isolated Notes

The rise and fall times are the times that the output voltage takes to get from zero to maximum. The rise time is dependent on the load resistor, since that is what's pulling the output up. Other factors include circuit impedance, the stability of the voltage supply, and the quality of the stimulus signal. An ideal circuit will have a response time that is the sum of the specification's propagation delay and rise or fall time. MEI recommends that one assumes that opto-isolated circuits will have a total response time between 100 and 200 microseconds.
