DESCRIP TION
TheL6220monolithicquaddarlingtonswitchis designedforhighcurrent,highvoltageswitchingapplications.Eachofthefour switchesis controlledby a
logicinput and all four are controlledby a common
inhibitinput.AllinputsareTTL-compatiblefor direct
connectiontologic circuits.
Eachswitchconsistsofanopen-collectordarlington
transistorplusafastdiodeforswitchingapplications
with inductive loads. The emitters of the four
switchesarecommoned.Anynumberof inputsand
outputsof thesamedevice may be paralleled.
Two versionsare available: theL6220 mountedin
a Powerdip 12 + 2 + 2 packageand the L6220N
mountedin a 15-leadMultiwattpackage.
