When I originally designed this circuit it was meant to be use as a pulse width modulated signal for a motor speed control. As such I have used it with both P & N type fetís and it has worked well.
However there is no reason they cannot drive an opto-coupler. The chips output is an open collector transistor (emitter to ground) and able to carry 16 milliamp.
