MAX485CSA+

RS-485/RS-422 Transceiver MAX485CSA+T

The MAX485CSA+T is a popular low-power transceiver (transmitter/receiver) designed by Maxim Integrated (now Analog Devices) for implementing RS-485 and RS-422 communication standards. The device enables bidirectional (half-duplex) serial communication over long distances, making it a key component in industrial automation, security, and access control systems. It features an unlimited slew-rate design, allowing data transmission speeds of up to 2.5 Mbps. The component is supplied in a compact SO-8 surface-mount (SMD) package.
