Criss cross resistor net?

  1. Apr 4, 2013 #1
    Does a criss-cross resistor network exist?

    I need something (preferably passive), that comes in both criss cross and straight paths.
    Maybe a switching array of some sort?
    I am looking for something that connects-
    A-->A
    B-->B
    C-->C
    D-->D

    and
    A-->D
    B-->C
    C-->B
    D-->A

    It can be 2 different parts for straight and cross connection. But the package has to be same.

    I know I can use FPGA/CPLD. But I want something simpler.

    What you want is called a passive crosspoint switch. You can easily make one yourself with a few resistors and four 2-1 analog muxes.

    Well, making one is the last option. I wanted to check if anything already existed.
