The MC3424 seriesisa dual-channel super~isory circuit, consisting 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, capable 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 or other exteris pinned-out for referertci!~g the input comparators, 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 .,~,:*~ + ~~,+, Activation of each chann~l’s outputs. An Input Enable pir] allows “,,,,?+\ ~ :i:;, ~,*P control of the input comparators. Aiihougt] this device is intended for power supply supervision,, the ‘K~~, pinrled-out refere!]ce, uncommitted ir)put comparators, and ,~’%~~ other features, enable the MC3424 series to be utiiized fo$W~d8 range of applications. $::,.,,~!sii:,i ei. ,,, . ?+?. ~~~..:ya~d @ Pinned-Out 2.5 V Ref~rence ~ >\’. ,C,t. @ Wide Common-Mode Range +,+};. ~ Hysteresis ~ Programmable ,,>.F P SUFFIX PLASTIC PACK.4GE CASE $48
