hello.. i dont know how to post my quetion so i m writing my question here..
i want to test HCPL 072 optocoupler but there are 2.4v on its VO pin without giving input signal to LED.. and when i give input signal then there are 5v on its VO pin..
i want to operate NPN transistor with optocoupler's VO pin.. but transistor turns on without giving input signal to optocoupler.. bcz there are already 2.4 volts..
