I designed a Master/Slave serial communications control system using a co-ex cable as the network medium.
It all works 100% over short distances, and to be quite truthful, I haven’t yet tested if for long distances (40-50m). I was planning on using the 74LS243 Bus Transceiver IC, but I don’t have any in stock to test with.
Question: How do I create the same functionality as the Bus Transceiver IC using just discrete components like transistors, diodes and resistors?
As a hobbyist my design sucks to say the least.
Can any of you smart Electronic Engineers perhaps model something for me on LTSpice? (Operating voltage 5V)
Thanks.
