DESCRI PT ION
This device consists of four independent precision voltage comparators. All these comparators were designedspecificallytooperatefroma singlepower supply over a wide range of voltages. Operation fromsplit power supplies is also possible.
These comparators also have a unique characteris-tic in that the input common-mode volt­age range includes ground even though operated froma singlepower supply voltage.

Notes : 2.
At output sw itch point, VO≈ 1.4V , RS=0withV range (0V to V
3. T he direction of the i nput current i s out of the IC due to the PNP i nput stage. This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference of i nput lines.
4. T he input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of t he common-mode volt age range is V can go to +30V without damage.
5. T he response time specifi ed is for a 100mV input step wi th 5mV overdrive.
6. P ositi ve excursions of i nput voltage may exceed the power supply level. As long as the other v oltage re­mains within the common-mode range, the comparator wi l l provide a proper output state. The low i nput voltage state m ust not be less than –0.3V (or 0.3V bellow t he negative power supply, if used).
7. M aximum values are guaranteed by design.
