Note 1: Absolute maximum ratings are limiting values, to be applied individually, and beyond which the serviceability of the circuit may be impaired. Functional
operability under any of these conditions is not implied. Exposure to maximum ratings for extended periods may affect device reliability.
Note 2: Data sheet min/max specification limits are guaranteed by design, test, or statistical analysis.
Note 3: Except power supply pins.
Note 4: Independent of supply voltage.
