Hello all, I want to serially communicate two pic16f628s, but the distance between them is long, i.e, more than 30 meter, do you know any integrated cicuit for obtaining greater voltages-currents from pic16f628 output pins (i.e., amplify) and at the receiver side convert it to the pic16f628 input level.
