    Hello


    Digital IO lines are not cheap. It becomes very costly when we require 100s of digital IOs. What would be the efficient way to generate IOs but cost effective.

    thanks

    1) Multiplexing to reduce the sheer number of I/Os.

    B) I/O Expanders

    C) a heap of cheap CMOS parallel buffers or serial shift registers.
