Note 1: Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. Under
“recommended operating conditions” the device operation is assured, but some particular parameter may not be achieved.
The electrical characteristics table defines the operation range of the device, the electrical characteristics is assured on DC and
AC voltage by test program. For the parameters without minimum and maximum value in the EC table, the typical value defines
the operation range, the accuracy is not guaranteed by spec.
Note 2: The maximum power dissipation decrease if temperature rise, it is decided by TJMAX, θ JA, and environment
temperature (TA). The maximum power dissipation is the lower one between PDMAX = (TJMAX - TA)/ θ JA and the number
listed in the maximum table.
Note 3: Human Body mode, 100pF capacitor discharge on 1.5KΩ resistor
