  • CMOS bus driver circuit
    Patent number: 6411125
    Abstract: A CMOS bus driver circuit includes an output stage of two complementary MOS transistors and an input stage, where in the connection of the source-drain paths of the MOS transistors (P1, N1) of the input stage a diode (D) is inserted so that the flow of a current in the direction of the MOS transistor (P1) connected to the supply voltage terminal (14) of the input stage is blocked, its cathode being connected to the gate of the one MOS transistor (P2) of the output stage. Connected in parallel to the diode D is the source-drain path of a further MOS transistor (P4), the gate of which is connected to the circuit output (18).
