May 1997
QUAD DARLINGTON SWITCH
.
FOUR NON INVERTING INPUTS WITH
ENABLE
.
OUTPUT VOLTAGE UP TO 60 V
.
OUTPUT CURRENT UP TO 1.8 A
.
VERY LOW SATURATION VOLTAGE
.
TTL COMPATIBLE INPUTS
.
INTEGRAL FAST RECIRCULATION DIODES
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.
