(1)

VO

≅ 1.4 V, RS = 0Ω with V+ from 5 V to 30 V; and over the full input common-mode range (0 V to V+ - 1.5 V) at 25°C.

(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 no loading change exists on the input lines.

(3)

The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V (at 25°C). The

upper end of the common-mode voltage range is V+ - 1.5 V at 25°C, but either or both inputs can go to +32 V without damage,

independent of the magnitude of V+.
