Notes: “x” defines port numbers, 0 to 11, inclusive.
(1) 80 VDC is the transient voltage that can be applied for up to one minute.
(2) Maximum voltage value between grounds.
(3) ESD Human Body Model is: (CZap = 100 pF, RZap = 1500 Ω).
Stresses beyond those listed above can cause permanent damage to the device. Exposure to absolute maximum rating
conditions for extended periods could affect device reliability.
