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 VSS with a

high resistor of 1MΩ (typ.). The equivalent circuit of each input pin is shown below: (Resistance value: typ.)
