MAX3157CAI+ Product Details

The MAX3157CAI+ is a high CMRR RS485 transceiver with ±50V isolation in 28 pin SSOP package. The high CMRR RS485/RS422 data communications interface providing ±50V isolation in a hybrid microcircuit. A single +5V supply on the logic side powers both sides of the interface with external ±50V capacitors transferring power from the logic side to the isolated side. Each MAX3157CAI+ contains one transmitter and one receiver and operates at a data rates up to 250Kbps. Drivers are short-circuit current limited and protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high impedance state. The receiver input has a fail-safe feature that has a logic high receiver output if the inputs are open, shorted or connected to a terminated transmission line with all drivers disabled.
