    Hey,
    Description:
    In my project i got one xor(2 input) and one nor(2 input) gate. Im using cmos and since there is 4 gates on each IC, and both have 3 unused gates. I would like to reduce it to one IC.

    Question:
    Do you know how to make an XOR from 3 NOR gates? OR the other way around.. NOR from 3 XOR gates.

    ???
    Would a wired-OR (or diode-OR) circuit feeding into one input of an XOR ckt, with the other input tied high be feasible?

    Just askin'
