Abstract
A multiplexer circuit includes a plurality of switch circuits coupled between respective input nodes and an output node. The switch circuits include first and second switch elements coupled in series, at an intermediate node, between the respective input node and the output node. A third switch element is coupled between an output of a buffer and the intermediate node. The buffer is configured to generate a buffered voltage based on the output voltage. When a particular switch circuit is selected, its respective first and second switch elements are active while its third switch element is inactive, resulting in a path between its input node and the output node. When the particular switch circuit is not selected, its third switch element is active while its first and second switch elements are inactive. The buffered voltage is driven to the intermediate node via the active third switch element.
