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. © 2007 California Micro Devices Corp. All rights reserved. 03/30/07 490 N.
