Tool/software:
Hi team ,
Whether RE# should be pulled down or high.I am seeing one of the reference both DE and RE are Pulled down
Hi Jaya,
Thanks for reaching out.
RE/ is an active low input where as DE is active high input. In case of half duplex operation you can short DE and RE/ so that device is either transmitting or receiving at any given time.
RE/ is internally pulled high so you really don't need any pull up on outside. Can you share the details of the reference you're referring to above for us to review better?

Hi Jaya,
Yes, that will ensure no floating voltage at DE when the line is pulled low for RE/
