The L6221 monolithic quad darlington switch is de-
signedfor high current, high voltageswitching appli-
cations. Each of the four switches is controlled by a
logic input and all four are controlled by a common
enableinput.All inputsare TTL-compatiblefor direct
connection to logic circuits.
Eachswitch consists of an open-collectordarlington
transistorplus a fast diodefor switchingapplications
with inductivedevice loads. The emitters of thefour-
switches are commoned. Any numberof inputs and

Three versions are available : the L6221C mounted
in a Powerdip 12 + 2 + 2 package and the L6221CN
mounted in a 15--lead Multiwatt package, the
L6221CDin SO16+2+2 package.
