CAUTION:

While all input and output pins have inter-

nal protection networks, these parts should

be considered ESD (ElectroStatic Dis-

charge) sensitive devices. Permanent dam-

age may occur on unconnected devices sub-

ject to high energy electrostatic fields. Un-

used devices must be stored in conductive

foam or shunts. Personnel should be prop-

erly grounded prior to handling this device.

The protective foam should be discharged to

the destination socket before devices are re-

moved.
