This current is essentially constant, independent of the output state,therefore, no loading changes will exist on the input lines.6.Input common mode of either input should not be permitted to go more than 0.3 V negative of ground or minus supply. The upper limit ofcommon mode range is V CC −1.5 V.7.Response time is specified with a 100 mV step and 5.0 mV of overdrive. With larger magnitudes of overdrive faster response times areobtainable.8.The comparator will exhibit proper output state if one of the inputs becomes greater than V CC, the other input must remain within the commonmode range. The low input state must not be less than −0.3 V of ground or minus supply.LM293/393LM2903Figure 2. Input Bias Current versusPower Supply Voltage Figure 3.

This gives the device oscillation tendencies if the outputs are capacitively coupled to the inputs via stray capacitance. This oscillation manifests itself during output transitions (V OL to V OH ). To alleviate this situation, input resistors <10 k W should be used.The addition of positive feedback (<10mV) is also recommended. It is good design practice to ground all unused pins.Differential input voltages may be larger than supply voltage without damaging the comparator’s inputs. V oltages more negative than −0.3 V should not be used.Figure 8. Zero Crossing Detector(Single Supply)Figure 9. Zero Crossing Detector(Split Supply)Figure 10.
