Input Equivalent Circuit
To prevent static charges, protective diodes are provided for each pin except the power supplies. In addition,
protective resistors are added to all pins except the video signal inputs. All pins are connected to V
SS
with a
high resistor of 1M
(typ.). The equivalent circuit of each input pin is shown below: (Resistance value: typ.)
