Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Unless otherwise specified, (V_CC – GND) = 20V and the output
load is referred to the ground pin (GND) of the device. Positive current
values are defined to flow out of the device.
Note 3: For input voltages greater than 2.4V the device Is guaranteed to be
turned on. 1.5V is the typical threshold at 25°C.
Note 4: For input voltages less than 0.8V, the device is guaranteed to be in
an off state. 1.5V is the typical switch threshold at 25°C.
Note 5: For reactive loads such as large capacitors, the output falltime will
be determined by the load.
