Note 1:
2:
Input voltages may exceed the supply voltages provided that input current is limited to ±100 μA. Current above this
value may result in invalid display readings, but will not destroy the device if limited to ±1 mA.
Dissipation ratings assume device is mounted with all leads soldered to printed circuit board.
