Product Introduction
The MAX3483, MAX3485, MAX3486, MAX3488, MAX3490, and MAX3491 are 3.3V, low- power transceivers for RS- 485 and RS- 422 communication. Each part contains one driver and one receiver. The MAX3483 and MAX3488 feature slew- rate- limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error- free data transmission at data rates up to 250kbps. The partially slew- rate- limited MAX3486 transmits up to 2.5Mbps. The MAX3485, MAX3490, and MAX3491 transmit at up to 10Mbps.
Drivers are short- circuit, current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high- impedance state. The receiver input has a fail- safe feature that guarantees a logic- high output if both inputs are open circuit.
The MAX3488, MAX3490, and MAX3491 feature full- duplex communication, while the MAX3483, MAX3485, and MAX3486 are designed for half- duplex communication.
