In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are measured
with respect to ground (pin 11); positive currents flow into the chip; pin V
driven. The voltage ratings are valid provided other ratings are not violated; current ratings are valid
provided the maximum power rating is not violated.
