MAX3157CAI+ General Description

The MAX3157CAI+ is a precision, high-speed, low-power RS-485/RS-422 transceiver. It operates over a wide supply voltage range of 3V to 5.5V and supports data rates up to 20Mbps. This device features ±15kV ESD protection on RS-485 I/O pins, making it robust in harsh industrial environments. Its low quiescent current of 300µA maximizes efficiency in battery-powered applications. The MAX3157CAI+ incorporates a fail-safe circuitry to ensure a logic-high receiver output when inputs are open or shorted. It also includes hot-swap circuitry to prevent data corruption during live insertion or removal from a loaded data line. With a small footprint and industry-standard pinout, it facilitates easy integration into various designs. The MAX3157CAI+ is suitable for applications requiring high-speed, half-duplex communication over long distances, such as industrial automation, HVAC control, and motor control systems
