MAX3490EESA+T Description

Devices in the MAX3483E family (MAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E) are±15kV ESD-protected, +3.3V, low-power transceivers forRS-485 and RS-422 communications. Each device contains one driver and one receiver. The MAX3483E andMAX3488E feature slew-rate-limited drivers that minimizeEMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission atdata rates up to 250kbps. The partially slew-rate-limitedMAX3486E transmits up to 2.5Mbps. The MAX3485E,MAX3490E, and MAX3491E transmit at up to 12Mbps.All devices feature enhanced electrostatic discharge(ESD) protection. All transmitter outputs and receiverinputs are protected to ±15kV using IEC 1000-4-2 AirGap Discharge, ±8kV using IEC 1000-4-2 ContactDischarge, and ±15kV using the Human Body Model.Drivers are short-circuit current limited and are protected against excessive power dissipation by thermalshutdown circuitry that places the driver outputs into ahigh-impedance state. The receiver input has a fail-safefeature that guarantees a logic-high output if bothinputs are open circuit.The MAX3488E, MAX3490E, and MAX3491E featurefull-duplex communication, while the MAX3483E,MAX3485E, and MAX3486E are designed for halfduplex communication.
