Abstract: An apparatus relating generally to an analog multiplexer is disclosed. In such an apparatus, the analog multiplexer has first select circuits and at least one second select circuit. The first select circuits have respective input nodes and output nodes. The output nodes are all coupled to one another to provide an output node of the analog multiplexer. The first select circuits are coupled to a first supply voltage of a first supply domain. The at least one second select circuit is coupled to a second supply voltage of a second supply domain different from the first supply domain. The at least one second select circuit has an input port and an output port. The output port is coupled to an input node of the input nodes.
