The MAX3491EESD+T is a low-power, single-supply, differential bus transceiver manufactured by Analog Devices and Maxim Integrated. The device provides a 3.3V supply voltage and is designed to meet the electrical requirements for RS-422 and RS-485 Serial Data Bus (SDB) communications standards. It features a 12Mbps data rate and features a slew rate of 400kV/µs (typ). The MAX3491EESD+T also includes several on-chip features such as, a low-power sleep mode, thermal overload protection, overvoltage detection, and fault-tolerant discharge. The device is suitable for industrial automation, implementing point-to-point and multi-drop bus structures. It is also suitable for automation tasks in harsh environmental conditions. The MAX3491EESD+T is available in a 8-Pin SOIC package.
