Caution: Permanent damage to the chip may result if absolute maximum ratings are exceeded.
Ensure so that the impressed voltage does not exceed 4.3 V for pins for which the
maximum rating is determined by the voltage on the V
CC
, AV
CC
, and V
CL
pins, or 7.0 V for
pins for which the maximum rating is determined by V
CC
B.
The V
CC
and V
CL
pins must be connected to the Vcc power supply.
