1. CAUTION: ESD (electrostatic discharge) sensitive device. The digital control inputs are diode protected; how-

ever, permanent damage may occur on unconnected devices subject to high energy electrostatic fields. Unused

devices must be stored in conductive foam or shunts. The protective foam should be discharged to the destina-

tion socket before devices are inserted.
