Notes: “x” defines port numbers, 0 thru 3, inclusive.
(1) _{80 V is the transient voltage that can be applied for 1 min max.}
(2) _{Maximum value between grounds.}
(3) _{ESD testing is performed in accordance with the Human Body}
Model (CZap = 100 pF, RZap = 1500 Ω).
(4) _{with 4ML PCB – no air flow}
Stress beyond those listed above may cause permanent damage
to the device. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
