Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is
not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratlng
conditions for extended periods may affect device reliability.
The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
Due to the limited drive capability use for input of the same package only.
Junction-to-board resistance assumes exposed pad is soldered (or equivalent) to the device’s most negative potential on the pcb.
The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
Specification for packaged product only.
Due to the internal termination (see Figure 2a) the input current depends on the applied voltages at IN, /IN and V
of voltages that causes the input current to exceed the maximum limit!
