Explanation of Maxim RS-485 Features

Abstract: Features are described for Maxim's large selection of RS-485 transceivers. Devices are identified to meet requirements for half- or full-duplex operation, supply voltages down to 2.5V, ESD protection up to ±15kV, data rates from 250kbps to 12Mbps, slew-rate limited devices for low radiated noise operation, fail-safe operation with open or shorted cables, normal 1 unit-load to 1/8 unit-load for expanded networks, and low-power shutdown operation.
