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 the four-

switches are commoned. Any numberof inputs and

outputs of the same device may be paralleled.

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

L6221CD in SO16+2+2 package.
