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.

SPECIFICATIONS
