DESCRIP TION
TheL6221monolithicquaddarlington switchis designedforhighcurrent,highvoltageswitchingapplications.Eachof thefourswitchesis controlledby a
logicinput and allfourare controlledby a common
enableinput.AllinputsareTTL-compatiblefordirect
connectiontologic circuits.
Eachswitchconsistsofanopen-collectordarlington
transistorplusafastdiodeforswitchingapplications
withinductivedeviceloads.The emittersof thefour
switchesare commoned.Anynumberofinputsand
outputsof the samedevice maybe paralleled.
