PACUSB-U1/U2/U3

Specifications (con’t)

Note 1: ESD applied to input/output/V3.3 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 6). Unused pins are

open.

Note 2: These parameters guaranteed by design.
