(1)

All characteristics are measured with zero common-mode input voltage, unless otherwise specified.

(2)

The voltage at either input or common-mode must not be allowed to go negative by more than 0.3 V. The upper end of the common-

mode voltage range is VCC+ – 1.5 V; however, one input can exceed VCC, and the comparator will provide a proper output state as long

as the other input remains in the common-mode range. Either or both inputs can go to 30 V without damage.
