This is a experiment about a 2 wire latched shift register driver. Latched shift registers usually needs 3 signal wires to work. In this post I will show how to drive such a shift register using a propagation delay circuit made out from discrete parts, in this case 3 transistors and 5 resistors. With this setup you can save one microcontroller pin.
