The MC3424 seriesisa dual-channel super~isory circuit, consist-
ing of two uncommitted input comparators, a reference, otdtput
comparators, with high current Drive ar)d !r}dicator outputs for eac!~
channel. The input comparators feature programmable k)ys~eresis,
high common-mode rejection, and wide commoYI-rnode range, capa-
ble of comparing at ground potentia! with single-supply operation.
Separate De/ay pins are provided tO increase noise immunity by
de[aying atiivation of the outputs. A2.5 V bandgap vo!tage reference
is pinned-out for referertci!~g the input comparators, or other exter-
nal functions. Independent high current Drive and Indicator ~utputs
for each channel can source and sink up to 300 mA and 30 mA
respectively, Cfd OS/TTL compatible digital inputs provide Reii;ote
