MAX481/MAX483/MAX485/ MAX487MAX491/MAX1487 Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers General Description Next Generation Device Features The MAX481, MAX483, MAX485, MAX487MAX491, and For Fault-Tolerant Applications MAX1487 are low-power transceivers for RS-485 and RS- MAX3430: 80V Fault-Protected, Fail-Safe, 1/4 422 communication. Each part contains one driver and one Unit Load, +3.3V, RS-485 Transceiver receiver. The MAX483, MAX487, MAX488, and MAX489 MAX3440EMAX3444E: 15kV ESD-Protected, feature reduced slew-rate drivers that minimize EMI and 60V Fault-Protected, 10Mbps, Fail-Safe, reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. RS-485/J1708 Transceivers The driver slew rates of the MAX481, MAX485, MAX490, For Space-Constrained Applications MAX491, and MAX1487 are not limited, allowing them to MAX3460MAX3464: +5V, Fail-Safe, 20Mbps, transmit up to 2.5Mbps. Profibus RS-485/RS-422 Transceivers These transceivers draw between 120A and 500A of MAX3362: +3.3V, High-Speed, RS-485/RS-422 supply current when unloaded or fully loaded with disabled Transceiver in a SOT23 Package drivers. Additionally, the MAX481, MAX483, and MAX487 have a low-current shutdown mode in which they consume MAX3280EMAX3284E: 15kV ESD-Protected, only 0.1A. All parts operate from a single 5V supply. 52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422, Drivers are short-circuit current limited and are protected True Fail-Safe Receivers against excessive power dissipation by thermal shutdown MAX3293/MAX3294/MAX3295: 20Mbps, +3.3V, circuitry that places the driver outputs into a high-imped- SOT23, RS-485/RS-422 Transmitters ance state. The receiver input has a fail-safe feature that For Multiple Transceiver Applications guarantees a logic-high output if the input is open circuit. MAX3030EMAX3033E: 15kV ESD-Protected, The MAX487 and MAX1487 feature quarter-unit-load +3.3V, Quad RS-422 Transmitters receiver input impedance, allowing up to 128 MAX487/ MAX1487 transceivers on the bus. Full-duplex communi- For Fail-Safe Applications cations are obtained using the MAX488MAX491, while MAX3080MAX3089: Fail-Safe, High-Speed the MAX481, MAX483, MAX485, MAX487, and MAX1487 (10Mbps), Slew-Rate-Limited RS-485/RS-422 are designed for half-duplex applications.
