The maximum output current may be as high as 20 ma, independent of the magnitude of, output short circuits to can cause excessive heating and eventual destruction. 5. At output switch point, V O.4 Vdc, R S = 0 with from 5.0 Vdc to 30 Vdc, and over the full input common mode range (0 V to =.5 V). 6. 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 lines. 7. 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 of common mode range is.5 V.. Response time is specified with a 00 mv step and 5.0 mv of overdrive. With larger magnitudes of overdrive faster response times are obtainable. 9. The comparator will exhibit proper output state if one of the inputs becomes greater than, the other input must remain within the common mode range. The low input state must not be less than 0.3 V of ground or minus supply. 3

5 APPLICATIONS INFORMATION These dual 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 during output transitions (V OL to V OH ). To alleviate this situation, input resistors <0 k should be used. +5 V The addition of positive feedback (<0 mv) 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. Voltages more negative than 0.3 V should not be used.
