QUAD DARLINGTON SWITCH
L6221AS L6 221AD 6221NJune 2003
QUAD DARLINGTON SWITCH FOUR NON INVERTING INPUTS WITH
ENABLE. OUTPUT VOLTAGE UP TO 50 V. OUTPUT CURRENT UP TO 1.8 A. VERY LOW SATURATION VOLTAGE. TTL COMPATIBLE INPUTS. INTEGRAL FAST RECIRCULATION DIODES
DESCRIPTIONThe 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.
