Notes

(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.
