• The resistors that are inserted into each pin are to protect the IC. They help to remove ESD and latch-up

damages.

• The capacitors help to reduce the effects of transient variations in voltage and electromagnetic waves,

and to improve ESD tolerance of the IC.

Please use either C2 or C3, or both of them by request of your application.

• These values in the above figure are for example. Please choose appropriate values.
