The SN75161BDWR can support data rates up to 100 Mbps.
Yes, the SN75161BDWR is compatible with other RS-485 transceivers that comply with the EIA/TIA-485 standard.
To ensure reliable communication in noisy environments, use twisted-pair cables, keep the cable length as short as possible, and use proper termination and shielding.
The maximum cable length supported by the SN75161BDWR depends on the data rate and cable characteristics, but a general guideline is to keep the cable length below 4000 feet (1219 meters) at 100 Mbps.
The SN75161BDWR can be configured for half-duplex or full-duplex operation by connecting the DE (driver enable) pin to VCC or GND, respectively.
