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