Notes:
1. Functional and tested operating conditions are given in
Table 3
. Absolute maximum ratings are stress ratings only, and functional operation
at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause permanent damage to the device.
2.
Caution:
Vin must not exceed OV
