Note 4.
Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended.
Shutdown current is defined as the sum of current going into pin 1, 5, and 6 when the device is disabled.
