2 Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond
the maximum rating may affect device reliability or cause permanent damage to the device.
3 CAUTION: All “5 V Tolerant” input voltages must not be more than 3.95 V greater than the supply voltage; this restriction
applies to “power on”, as well as during normal operation. In any case, the input voltages cannot be more than 5.75 V. “5 V
Tolerant” inputs are inputs that tolerate 5 V.

Junction-to-ambient thermal resistance1, 2 Natural Convection
1 Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site
(board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and board
thermal resistance.
