CAUTION: ESD (ElectroStatic Discharge) sensitive device. Permanent damage may occur on unconnected devices subject to high energy 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 (Typical @ 25 °C with V CC = +15V, VEE = 0V, VLOGIC = +5V unless otherwise noted.)
