  • Three state bus driver with protection circuitry
    Patent number: 4178620
    Abstract: A protective circuit arrangement for three state bus drivers, incorporating insulated gate field effect transistors, affords protection against short circuiting of the output bus. The protective circuit senses the short circuit condition at the output bus of two push-pull output transistors and feeds back a signal to the input circuit of the ON transistor which reduces the input drive to that transistor and limits the output current through that transistor to a safe value.
