ABSTRACT:
A dynamic priority multiplexer including a complementary pair of evaluation devices responsive to a clock signal defining evaluation periods, and multiple evaluation legs coupled in cascade between a top node and a bottom node and arranged in order of priority. The complementary pair includes a pull-up device that pre-charges the top node and a pull-down device that pulls the bottom node low during evaluation. Each higher priority evaluation leg receives a corresponding select signal and a corresponding data signal and includes a corresponding pass device. A select signal, when asserted, enables evaluation of a corresponding data signal and disables a corresponding pass device. The lowest priority evaluation leg includes a pull-down data device that receives a lowest priority data signal and which is coupled between a pass device of a higher priority evaluation leg and the bottom node.
