Electrical Specification
All voltages are referenced to ground (GND). Positive
currents flow into the IC.
The maximum ratings given in the table below are
limiting values that do not lead to a permanent damage of
the device but exceeding any of these limits may do so.
Long term exposure to limiting values may effect the
reliability of the device.
