SN65HVD485E: Layout example error in datasheet

Part Number: SN65HVD485E


Hello, I believe there is an error in figure 9-6 in the datasheet for this part.  The figure shows the DE and !RE pins being connected to D and R respectively through resistors, with vias indicating that D and R are directly tied to GND.  I believe that the D and R traces should not connect to the pull-down resistors for DE and !RE.

Here is how I believe the figure was intended to look:

    Hi Scott,

    You are correct - the second one is what was intended. Resistors shouldn't really exist between enable lines and data lines in standard applications.

    I have added it to our backlog of datasheet typos/errors. 

    Thanks for pointing out this issue!

    Best,
