  • Driver circuit for an attachment unit interface used in a network system
    Patent number: 5309036
    Abstract: A driver circuit is to be used with an attachment unit interface in a network system and receives complementary data signals and an enable signal from constant current source and a differential transistor pair which includes a pair of differential transistors and a pair of load resistors. Each of the differential transistors has a gate terminal which receives one of the complementary data signals, a drain terminal which is connected to one of the load resistors, and a source terminal which is connected to the constant current source. A switch network is connected to the drain terminal of the differential transistors and is activated by the enable signal so as to generate a differential voltage output. Each of a pair of source followers has a gate terminal connected to the switch network and a source terminal The source followers receive the differential voltage output from the switch network.
