NOTES:

1. Positive excursions of input voltage may exceed the power supply level by 17V. 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 –0.3VDC (or

0.3VDC below the magnitude of the negative power supply, if used).

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

V+ – 1.5VDC). Inputs of unused comparators should be grounded.

3. The input common–mode voltage or either input signal voltage 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, but either or both inputs can go to 30VDC 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 100mV input step with a 5mV overdrive. For larger overdrive signals, 300ns can be obtained (see typical

performance characteristics section).
