Note 2: All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to ground unless otherwise
specified.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
The q denotes specifications which apply over the full operating temperature range, otherwise specifications are TA = 25°C.
V12VIN = 12V, VEE = – 12V, V3VIN = 3.3V, V5VIN = 5V.(Note 2)
