At output switch point, Vo = 1.4V, Rs = 0 with Vcc* from 5Vto 30V, and over the full input common-mode range (OV to Vec* -1.5). 3. The direction of the input currant is out of the IC due to the PNP input stage. This current is essentially con- stant, independent of the state of the output, so no loading charge exists on the reference of input lines. 4. The input common-mode voltage of either input signal vottage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is Vcc* -1.5V, but either or both inputs can go to +30V without damage. 5, The response time specified is for a 100mV input step with SmV overdrive. For larger overdrive signals 300ns can be obtained. 6 . Positive excursions of input voltage may exceed the power supply 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 -0.3V (or 0.3V bellow the negative power supply, if used).
