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 includesground even thoughoperatedfrom a single power supply voltage.

No tes :	2. At out put switch point, VO ≈ 1.4V, RS = 0Ω with VC C+ from 5V to 30V and over the full input common-mode range
	(0V to VCC+ 1.5V).

3.The direct ion of the input current is out of the IC due to the PNP i nput stage. T his current 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 signal 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 VC C+ ±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 wit h 5mV overdrive. For l arger overdrive 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 comparator 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).
