5.2 Electrical Characteristics
Input Signal:
Each input signal is connected to the LED (cathode side) of the photo-coupler. The LED
(anode side) is connected to the pull-up power supply voltage.
Output Signal:
Each output signal is outputted via an open collector by using a photo-coupler. The voltage
of each output is obtained by connecting pull-up resistors, inside or outside of the
AT682/683.
