Note 2: ESD applied to input and output pins with respect to GND, one at a time. Clamping voltage is measured at the opposite side
of the EMI filter to the ESD pin (i.e. if ESD is applied to pin 1 then clamping voltage is measured at pin 8).
Note 3: These parameters guaranteed by design and characterization.
