Note:
²*² It is recommended that this component is added for added ESD protection.
²**² It is recommended that this component is added in environments where power line noise is significant.
²#² may be resistor or capacitor. The resistance of ²#² must be greater than 1kW or the capacitance of ²*² must
be less than 1nF.
