Due to the PNP transistor inputs, bias current will flow out of the inputs. This current is essentially constant, independent of the output state,therefore, no loading changes will exist on the input Input common mode of either input should not be permitted to go more than V negative of ground or minus supply.
6 The upper limit ofcommon mode range is VCC Response time is specified with a 100 mV step and mV of overdrive. With larger magnitudes of overdrive faster response times The comparator will exhibit proper output state if one of the inputs becomes greater than VCC, the other input must remain within the commonmode range. The low input state must not be less than V of ground or minus , LM393E, LM293, lm2903 , LM2903E, lm2903v , 2. Input Bias Current versusPower Supply VoltageFigure 3.

This gives the device oscillationtendencies if the outputs are capacitively coupled to theinputs via stray capacitance. This oscillation manifestsitself during output transitions (VOL to VOH). To alleviatethis situation, input resistors < 10 k should be addition of positive feedback (< 10 mV) is alsorecommended. It is good design practice to ground allunused input voltages may be larger than supplyvoltage without damaging the comparator s inputs.
