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.
