At output switch point, VO ≈ 1.4V, RS = 0Ω with VCC + from 5V to 30V and over the full input common-mode range (0V to VCC + -1.5V). 2. 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 there is no loading charge on the reference or input lines. 3. 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 below the negative power supply, if used). 4. The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals, 300ns can be obtained. |
