DESCRIPTION These devices consist of two independent low power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even thoughoperatedfrom a single power supply voltage.

2. At out put switch point, VO 1.4V, R S = 0 with VC C+ fr om 5V to 30V and over the full input common-mode range (0V to V CC + 1.5V). 3. The direct ion of the input current is out of the IC due to the PNP i nput stage. T his cur rent is essent ial ly const ant, independent of the state of the output, so no loadi ng charge exists on the reference or input l ines. 4. The input common-mode volt age of either input si gnal vol tage shoul d not be all owed to go negat ive by more than 0.3V . The upper end of the common-mode vol tage range is VCC + -1.5V , but either or bot h inputs can go to +30V wi thout damage. 5. The response ti me specifi ed is for a 100mV i nput step w it h 5mV overdr ive. For l arger over drive signal s 300ns can be obtained. 6. Posit ive excursions of i nput voltage may exceed the power suppl y level. A s l ong as the other voltage remai ns within the common-mode range the compar ator wil l provide a proper output state. The low input voltage state must not be less than -0.3V (or 0.3V below the negat ive power supply, if used).
