Table 9: Absolute Maximum Ratings
Power: VDD Pin
The power supply for the device must be connected to the VDD
pin. The voltage should be +5 VDC and should be supplied to the
part through a regulator that has good noise rejection and an
adequate current rating. The controller requires up to a maximum
of 11mA with V

=5.00V.
Figure 14: Open Circuit Reference Example
Grounding: VSS, AVSS Pins
There are two ground pins. Both pins must be connected together
at the device. This point must have a direct connection to a solid
ground plane.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only.
Functional operation of the device at the Absolute Maximum Ratings or other conditions not consistent with the characteristics shown in this
document is not recommended. Exposure to absolute maximum rating conditions for extended periods may affect product reliability.
