Abstract
A multi-voltage multiplexer system includes multiple voltage inputs, each voltage input providing a different input voltage, and multiple control inputs operative to select one of the input voltages for output. Each of multiple transistors is connected to a different one of the voltage inputs and to a different one of the control inputs, and the transistors are connected to an output such that the selected input voltage is provided at the output. A bulk of each of the transistors is connected together to form a bulk network, and the bulk network is connected to the gate of each transistor such that the transistors connected to non-selected voltage inputs have gates set at approximately the maximum of the input voltages.
