DESCRIPTION

· The L6221 is a monolithic quad Darlington switch designed for high current and high voltage switching applications.

· Each of the four switches is controlled by a logic input, with all four switches also controlled by a common enable input.

· The switch includes an open-collector Darlington transistor and a fast diode for inductive device loads.

· The emitters of the four switches are commoned, allowing any number of inputs and outputs to be paralleled.

FEATURES

· 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.

APPLICATIONS

· High current, high voltage switching applications.
