Abstract
A dynamic logic multiplexer has pull-ups on its input signals that pull-up the input signals when not selected. This reduces leakage current that may contribute to incorrect switching of the output. The output stage of the multiplexer includes a latched dynamic node followed by two gain stages, and an open-drain output.
