*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

NOTE
Pins 1 and 16 are reserved for test purposes. Ideally these pins should be left
unconnected. If routing through these pins is required, then both should be at
the same potential (i.e., connected together).
