RS-485 bus transceiver — supply rail and data rate
The MAX3085ESA+T is a half-duplex RS-485/RS-422 transceiver from Analog Devices, integrating one driver and one receiver in an 8-SOIC package. Data rate is specified at 500 kbps, which suits multi-drop RS-485 networks where cable lengths exceed 100 m and the bus capacitance limits the toggle rate. The 100 mV receiver hysteresis provides noise margin on long runs in electrically noisy environments.
