                                   RS-485/RS-422 Transceivers

                        General Description                   __Next Generation Device Features                          MAX481/MAX483/MAX485/MAX487MAX491/MAX1487

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,          RS-485/J1708 Transceivers
thus allowing error-free data transmission up to 250kbps.
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
                                                                    MAX3362: +3.3V, High-Speed, RS-485/RS-422
These transceivers draw between 120A and 500A of                  Transceiver in a SOT23 Package
supply current when unloaded or fully loaded with disabled          MAX3280EMAX3284E: 15kV ESD-Protected,
drivers. Additionally, the MAX481, MAX483, and MAX487               52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,
have a low-current shutdown mode in which they consume              True Fail-Safe Receivers
only 0.1A. All parts operate from a single 5V supply.              MAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,
                                                                    SOT23, RS-855/RS-422 Transmitters
Drivers are short-circuit current limited and are protected
against excessive power dissipation by thermal shutdown        For Multiple Transceiver Applications
circuitry that places the driver outputs into a high-imped-         MAX3030EMAX3033E: 15kV ESD-Protected,
ance state. The receiver input has a fail-safe feature that         +3.3V, Quad RS-422 Transmitters
guarantees a logic-high output if the input is open circuit.
                                                               For Fail-Safe Applications
The MAX487 and MAX1487 feature quarter-unit-load                    MAX3080MAX3089: Fail-Safe, High-Speed
receiver input impedance, allowing up to 128 MAX487/                (10Mbps), Slew-Rate-Limited RS-485/RS-422
MAX1487 transceivers on the bus. Full-duplex communi-               Transceivers
cations are obtained using the MAX488MAX491, while
the MAX481, MAX483, MAX485, MAX487, and MAX1487                For Low-Voltage Applications
are designed for half-duplex applications.                          MAX3483E/MAX3485E/MAX3486E/MAX3488E/
                                                                    MAX3490E/MAX3491E: +3.3V Powered, 15kV
