I use a fast optocoupler(6n137) to interface two circuits. When ON signal comes to input, the output transistor immediately turns on without a significant delay. But when OFF signal comes to input, the output transistor of the optocoupler doesn't turn off immediately. It takes 6-7us to turn off. How can i reduce this time. The load is an igbt driver and optocoupler has a delay capability of sub microsecond at ON and OFF.
