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.
