4. The maximum output current may be as high as 20 mA, independent of the magnitude of V_CC, output short circuits to V_CC can cause
excessive heating and eventual destruction.
5. At output switch point, V_O]1.4 Vdc, R_S = 0 W with V_CC from 5.0 Vdc to 30 Vdc, and over the full input common mode range (0 V to
V_CC = −1.5 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 V_CC −1.5 V.
8. Response time is specified with a 100 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 V_CC, 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.
