ABSOLUTE MAXIMUM RATINGS
Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is
not implied.
(*) A higher positive voltage level can be applied to the pin with a resistor which limits the current flowing into the pin to 10mA maximum
THERMAL DATA
(*) This value is referred to one layer pcb board with minimum copper connections for the leads. a minimum value of 120 °C/W can be
obtained improving thermal conductivity of the board
