Input Offset Voltage

1. At output switch point, VO=1.4V, RS=0Ω with V+ from 5VDC to 30 VDC; and over the full input common-mode range (0VDC to

V+-1.5V

DC).

Range,2, V

CM = 0V

2. The direction of the input current is out of the IC due to the PNP input stage. This current essentially constant, independent of

the state of the output so no loading change exists on the reference or input lines.

3. The input common-mode voltage or either input voltage signal should not be allowed to go negative by more than 0.3V. The

upper end of the common-mode voltage range is V+-1.5V at 25°C, but either or both inputs can go to +30V without damage,

independent of the magnitude of V+.

5. Positive excursions of input voltage may exceed the power level as long as the other voltage remains within the common

mode range, the comparator will provide a proper output state. The low input voltage state must not be less than -0.3 V

DC (or

0.3V

DC below the magnitude of the negative power supply, if used) (at 25°C).
