I am using the multplexer chip cd4067 and was wondering whether it is possible to chnage the direction of a pin from an output to an input.

Change the direction on the multiplexer or on the Netduino?

Chnage direction from netduino...want some ports on 4067 to act as inputs and others act as outputs. But signal line can only connect to one pin on the netduino.

Try defining a port as a TriStatePort.
