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 1M

Ω (typ.). The equivalent circuit of each input pin is shown below: (The resistor value: typ.)
