Absolute Maximum Ratings
(Note 1)
Note 1:
The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the “Electrical
Characteristics” table are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.

Note 3:
Not more than one output should be shorted at a time, and the duration should not exceed one second.
Note 4:
I
CC1
is measured with all outputs OPEN, and all the inputs grounded.
Note 5:
I
CC2
is measured with the outputs OPEN, OUTPUT CONTROL at 4.5V and all other inputs grounded.
