Maxim Integrated MAX3097ECEE Multi-Channel RS-422/RS-485 Receiver

The Maxim Integrated MAX3097ECEE is a high-performance, multi-channel RS-422/RS-485 receiver designed to meet the demanding requirements of industrial communication systems. This robust integrated circuit is capable of receiving up to four differential data signals, making it an ideal solution for applications that require high data rates, noise immunity, and long cable runs.

The MAX3097ECEE features a quarter-load receiver input impedance, allowing up to 128 transceivers on the bus, which is four times more than standard RS-485/RS-422 receivers. This high-density receiver operates from a single 5V supply and is characterized for operation from -40°C to +85°C, ensuring reliable performance in a wide range of environments.

With a maximum data rate of 250kbps, the MAX3097ECEE is suitable for low-speed data communication in complex systems. It includes integrated fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted, or when they are connected to a terminated transmission line with all drivers disabled. This feature significantly enhances the safety and reliability of the communication system.

The device's proprietary low-power RS-485/RS-422 receivers consume just 375µA of supply current while unloaded, and only 1µA in shutdown mode, making it an energy-efficient choice for power-sensitive applications. Additionally, the MAX3097ECEE features ±15kV ESD protection on the receiver inputs, providing robust protection against electrostatic discharge events.

Available in a 16-pin QSOP package, the MAX3097ECEE is compact and suitable for space-constrained applications. Its integrated features and high level of integration make it a versatile component for designers working on industrial automation, HVAC systems, data acquisition systems, and networked devices requiring multiple channel communications.

Overall, the Maxim Integrated MAX3097ECEE is a reliable and efficient solution for multi-channel RS-422/RS-485 communication, offering the performance and features necessary to facilitate complex data transmission in industrial settings.
