    Do you have a circuit in mind (please post). You have to offer us a starting point for your question. Are you sensing multiple inputs, driving multiple 7-segment displays, what are you doing.

    Also, do you want to multiplex with software and the pins on the 8051 or do you want to drive an external 4000 series or 7400 series logic chip that can Mux?
