I'm using an LMV331 comparator in a battery powered circuit.
The comparator is powered by +5V while the open collector output
is connected through a resistor to +3.3V.
Because the comparator function is needed only intermittently, the
+5V to the comparator is switched off when the comparator is not
needed, but the +3.3V is constant.
Will the open collector output stay off (no current flow) when the
power to the comparator is switched off? I'm concerned about
parasitic diodes that might switch on.
