Notes: “x” defines port numbers, 0 thru 11, inclusive.

(1) 80 V is the transient voltage that can be applied for at most one minute.

(2) Maximum value between grounds.

(3) ESD testing is performed in accordance with the Human Body Model (CZap = 100 pF, RZap = 1500 Ω).

Stresses beyond those listed above, may cause permanent damage to the device. Exposure to absolute maximum rating conditions for

extended periods, may affect device reliability.
