DESCRIPTION
The L6221 monolithic quad darlington switch is de-
signedfor high current, high voltage switching 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
