ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of the device
at these or any other above those indicated in the operation
sections of the specifications below is not implied. Exposure to
absolute maximum rating conditions for extended periods of time
may affect reliability.

CAUTION:
While all input and output pins have
internal protection networks, these
parts should be considered ESD
(ElectroStatic Discharge) sensitive de-
vices. Permanent damage may occur on
unconnected devices subject to high en-
ergy electrostatic fields. Unused devices
must be stored in conductive foam or
shunts. Personnel should be properly
grounded prior to handling this device.
The protective foam should be discharged
to the destination socket before devices are
removed.
