DESCRIPTION

The L6221 monolithic quad darlington switch is de-

signed for 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 inputsareTTL-compatiblefor direct

connection to logic circuits.

Eachswitch consists of an open-collectordarlington

transistor plus a fast diodefor switchingapplications

with inductive device loads. The emitters of the four

switches are commoned. Any number of inputsand

outputs of the same device may be paralleled.
