Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

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 2: Unless otherwise specified, (V – 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 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.
