22.2 Circuit 2 – ccTalk Low Cost Interface
Assuming that the transmitting device is capable of sinking a reasonable amount of current,
a direct diode interface can be used rather than a full transistor interface. Although cheaper
to implement, this circuit does not have the drive capability or the robustness of other
designs.
