Hi Mick,
I’m not sure if you have any other masters but your RPI3 boards
already have a DS9503 on each channel.

I know this is a very basic question, but my electronics knowledge is
not great.
Following on from recent discussions re adding DS9503 to increase
reliability I am trying to design a PCB for them. Looking at the
diagram on page 2 of the spec sheet
(https://datasheets.maximintegrated.com/en/ds/DS9503.pdf)
<DS9503cct.jpg>
my understanding is that pin 1 is the signal line out to the devices,
pin 2 is the ground to devices, pin 5 is the ground to the adapter
and pin 6 is the signal line to the adapter.
I assume that I need to add the two 5 ohm resistor at pins 1 and 2.
Also there is no need for a resistor in the 5v line? Like this -
<DS9503MyCct.jpg>
Is that correct?
What power rating resistors are needed?
Thanks
Mick
