5. The bias current flows out of the inputs due to the PNP input stage. This current is virtually constant, independent of the output state.
6. The response time specified is for a 100 mV input step with 5.0 mV overdrive. For larger signals, 300 ns is typical.

APPLICATIONS INFORMATION
These quad comparators feature high gain, wide
bandwidth characteristics. This gives the device oscillation
tendencies if the outputs are capacitively coupled to the
inputs via stray capacitance. This oscillation manifests itself
of positive feedback (< 10 mV) is also recommended. It is
good design practice to ground all unused input pins.
Differential input voltages may be larger than supply
voltages without damaging the comparator’s inputs. Voltages
more negative than –300 mV should not be used.
