Analog Devices / Maxim Integrated MAX485ESA+T is a low-power RS-485/RS-422 half-duplex transceiver featuring one driver and one receiver, a 4.75–5.25V supply range and data rates up to 2.5Mbps. It provides 300µA typical quiescent current, standard 12kΩ receiver input resistance, support for 32 unit loads, selectable driver and receiver enables, open-circuit receiver fail-safe operation, short-circuit current limiting and thermal shutdown. The 8-pin narrow SOIC package is suitable for industrial serial communication, Modbus RTU, PLC interfaces and embedded control systems.
The Analog Devices / Maxim Integrated MAX3485EESA+T is a high-speed half-duplex RS-485/RS-422 transceiver integrating one differential driver and one receiver, operating from a 3.0V to 3.6V supply with a nominal 3.3V voltage and guaranteed data rates up to 12Mbps. The device features ±15kV Human Body Model ESD protection, ±8kV IEC contact-discharge protection, a −7V to +12V receiver common-mode input range, and open-input receiver fail-safe operation. Active-high driver enable and active-low receiver enable provide flexible bus-direction control, while low-power shutdown reduces typical supply current to 2nA. Integrated driver short-circuit current limiting and thermal shutdown improve reliability in demanding environments. Housed in an SOIC-8 package and rated from −40°C to +85°C, the MAX3485EESA+T is suitable for industrial RS-485 networks, PLC communication, microcontroller UART interfaces, embedded gateways, instrumentation and distributed control systems.
UMW SN75176BDR is a 5V half-duplex differential RS-485/RS-422 transceiver featuring one driver and one receiver for multipoint serial communication. It supports up to 32 standard unit loads, a -7V to +12V bus common-mode range, 12kΩ minimum receiver input resistance and 70mV typical receiver hysteresis. Additional features include three-state bus outputs, driver and receiver enable controls, thermal shutdown and short-circuit current limiting. The compact SOP-8 surface-mount package is suitable for industrial automation, PLC communication, Modbus RTU and embedded RS-485 networks.
