摘要： A circuit device having a transistor-based switch topology that substantially eliminates the possibility of latchup of the device. A series-connected low voltage threshold (LVT) N-channel transistor and a pull-up resistor are coupled across a switching (P-channel) transistor so that an integral body connection is provided for the switching transistor, which connects the body of the switching transistor to a node between the pull-up resistor and source terminal of the LVT transistor. The LVT transistor is connected with its gate and drain terminal connected to the output terminal of the switching transistor. The resistor is connected at its other end to the power supply side terminal of the switching transistor. The addition of these components in the particular configuration allows the body connection of the switching transistor to be automatically switched to the highest potential diffusion node.
