2

Normal operation, unless dual supply voltage was intended.

D
+IN3Input at V- (GND) is valid input, however, desired application result is unlikely. Output goes low if -IN is greater than zero volts.B
-IN4Input at V- (GND) is valid input, however, desired application result is unlikely. Output goes high if +IN is greater than zero volts.C
V+5Diodes from input to V+ may turn on due to input signal and cause electrical overstress (EOS). Main supply shorted. No power to device.B

Lowest voltage pin will drive V- pin internally via internal diode.

B
+IN3Floating input, circuit will likely not function as expected. Output may be high or low.C
-IN4

Floating input, circuit will likely not function as expected. Output may be high or low.
