Note 1:
Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device
should be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation.
Note 2:
Unless otherwise specified, all voltages are referenced to ground.
Note 3:
Unless otherwise specified, Min/Max limits apply over recommended operating conditions. All typicals are given for V
CC
= 5V and T
A
= 25˚C.
Note 4:

Note 5:
Ratings apply to ambient temperature at 25˚C. Above this temperature derate N Package 13.16 mW/˚C, J Package 15.38 mW/˚C, M Package 9.52 mW/˚C,
E Package 12.04 mW/˚C, and W package 6.94 mW/˚C.
