Hello. I am looking for greater detail on Figure 17 found in the SN65HVD01 datasheet, specifically in the Receiver and driver portions of the figure. I'm looking for the values of R1, R2, and R3, the details (part number with specs would be ideal) of the back to back zener diodes as well as the unidirectional zener diode, and the purpose/details of the current source in the receiver schematic. Thank you
