L6221AD Datasheet

Transistors Darlington 1.8 Amp Quad Switch


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. L6221AD Features • Four non-inverting inputs with enable• Output voltage up t0 50 V• Output current up t0 1.8 A• Very low saturation voltage• TTL compatible inputs• Integral fast recirculation diodes L6221AD Applications The L6221AD monolithic quad Darlington switch is designed for high current, high voltage switching applications.
