ELECTRICAL CHARACTERISTICS
Vcc=+5V and VDD=+5V) maximum ratings are stress ratings only and functional device operation is not implied.
Note 1: For operating at case temperatures above 25℃, the device must be derated based on a 150℃ maximum junction
temperature and a thermal resistance of θ
Note 2: Human body model, 100pF discharged through a 1.5KΩ resistor.
Note 3: The operating junction temperature maximum is 150℃.
