*Comments
Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to this device.
These are stress ratings only. Functional operation of this
device at these or any other conditions above those indicated
in the operational sections of this specification is not implied
or intended. Exposure to the absolute maximum rating
conditions for extended periods may affect device reliability.
! All voltage values are referenced to GND = 0V
! V1 to V5, must maintain VDD ≥ V1 ≥ V2 ≥ V3 ≥ V4 ≥ V5 ≥ GND
