MAXIM INTEGRATED / ANALOG DEVICES MAX3157CAI RS-485 Transceiver
The MAX3157CAI+ is a high CMRR RS-485 transceiver with ±50V isolation, capable of data rates up to 250 kbps. It features a fail-safe receiver, short-circuit current limited drivers, thermal shutdown protection, and supports full and half duplex configurations. Powered by a single +5V supply with external +50V isolation capacitors, it is ideal for industrial control, telecommunications, building automation, and remote sensing applications. The device's low power shutdown mode lowers current to 25µA, making it energy-efficient for remote and embedded systems.
