(1) The direction of the input current is out of the device. This current essentially is constant, independent of the state of the output, so no
loading change exists on the input lines.
(2) The input common-mode voltage of either input signal should not be allowed to go negative by more than 0.3 V. The upper end of the
common-mode voltage range is VCC+ â 1.5 V, but either or both inputs can go to 32 V without damage.
