Abstract

PURPOSE:To secure the insulation even for the transmitting circuit from the transmission line, by converting the input signal into the AC signal and then transmitting the AC signal to the transmission line via a transformer. CONSTITUTION:When input signal IN is in logic 1, the output emerging at output terminal Q repeats logics 1 and 0 by clock signal CLK. This signal is transmitted to transmission line 1 via transformer T and then rectified by diodes CR1 and CR2 to be transmitted to the receiving circuit via photocoupler PC after the smoothing through capacitor C1.
