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
enable input. All inputs are TTL-compatible for direct
connection to logic circuits.
Each switch consists of an open-collector darlington
transistor plus a fast diode for switching applications
with inductive device loads. The emitters of the four
switches are commoned. Any number of inputs and
outputs of the same device may be paralleled.
