Note 2: ESD applied to input and output pins with respect to GND, one at a time.
Note 3: Clamping voltage is measured at the opposite side of the EMI filter to the ESD pin (i.e. if ESD is applied to pin A1 then
clamping voltage is measured at pin C1). Unused pins are left open.
Note 4: These parameters are guaranteed by design and characterization.
