Product Description
L6221 Quad Darlington Switch
The L6221 is a monolithic quad Darlington switch designed for high current, high voltage switching applications. It features four non-inverting inputs with a common enable control, offering TTL-compatible inputs and very low saturation voltage. Each switch includes an open-collector Darlington transistor and a fast recirculation diode, making it suitable for applications with inductive loads. The emitters are commoned, and any number of inputs and outputs can be paralleled for increased current handling.
