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

We suggest to put in parallel channel 1 and 4 and channel2 and 3 as shown in figure 19 for the similar L6221C-L6221CN-L6221CD APPLICATION INFORMATION When inductive loads are driven by L6221C/CD, a zener diode in series with the integral free-wheeling diodes increases the voltage across which energy stored in the load is discharged and therefore speeds the current decay (fig ...
