NOTES:
1. Positive excursions of input voltage may exceed the power supply level by 17 V. 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 VDC (or
0.3 VDC below the magnitude of the negative power supply, if used).
2. At output switch point, VO ≈ 1.4 VDC, RS = 0 Ω with V+ from 5 VDC to 30 VDC; and over the full input common-mode range (0 VDC to
V+ – 1.5 VDC).
3. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of
the common-mode voltage range is V+ – 1.5 V, but either or both inputs can go to 30 VDC without damage.
4. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of
the output so no loading change exists on the reference or input lines.
5. The response time specified is for a 100 mV input step with a 5 mV overdrive. For larger overdrive signals, 300 ns can be obtained (see
Typical Performance Characteristics section).
