WebApr 8, 2015 · Since the first buffer has 0 - 5 volt outputs, I chose a family with 0 - 5 volt inputs. The 120 ohms is a series terminator, and the value is a typical impedance for UTP. You can still use the transmitter/receiver idea, since 3 wires twisted together in a cable will have an impedance, and ~100 ohms is a good starting point. WebMar 23, 2024 · Scamper.
