Hi Team,
quick question,
can our 485 IC implement intern loopback? Thanks.

With all half-duplex transceivers like this one, the receiver reads back the bus state when it is enabled.
It is no possible to have loopback without transmitting on the bus.
Hollis,
As Clemens said, there is no feature on our RS485 transceivers that allows for loopback from D->R without also transmitting on the A and B pins. We have something like this on some of our older CAN transceivers, but not RS485.
