ABSTRACT:
A multiplexer circuit includes switches 26 or 260 each having a hold portion 120 or 1200 and driving portion 110 or 1100 for providing a hold voltage or a select voltage to an output 14. If all control inputs 28A or 280A are at a first level, then the output has the select voltage, whereas if one input 28A is at a second level, the output has the hold voltage. The switches 26 may be integrated onto the substrate of a diode-based array of electrical elements, for example image sensing pixels. In this case, the output 14 includes a row conductor for a row of such pixels.
