CA UTION: ESD (Electro-Static Discharge) sensitive device.
Permanent damage may occur when unconnected devices are
subjected to high energy electrostatic fields. Unused devices must
be stored in conductive foam or shunts. Protective foam should be
discharged to the destination socket before devices are removed.
Devices should be handled at static safe workstations only. Unused
digital inputs must be grounded or tied to the logic supply voltage.
Unless otherwise noted, the supply voltage at any digital input
should never exceed the supply voltage by more than 0.5 volts or
go below –0.5 volts. If this condition cannot be maintained, limit
input current on digital inputs by using series resistors or contact
Hybrid Systems for technical assistance.
Specifications subject to change without notice.
