Hot-selling and scarce MAX485ESA+T Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers 8-SOIC spot stock

Product Descriptions

The MAX481, MAX483, MAX485, MAX487–MAX491, andMAX1487 are low-power transceivers for RS-485 and RS -422 communication . Each part contains one driver and onereceiver . The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize EMI andreduce reflections caused by improperly terminated cables,thus allowing error-free data transmission up to 250kbps .The driver slew rates of the MAX481, MAX485, MAX490,MAX491, and MAX1487 are not limited, allowing them totransmit up to 2.5Mbps .

These transceivers draw between 120µA and 500µA ofsupply current when unloaded or fully loaded with disableddrivers . Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consumeonly 0.1µA .All parts operate from a single 5V supply .

Drivers are short-circuit current limited and are protectedagainst excessive power dissipation by thermal shutdowncircuitry that places the driver outputs into a high-impedance state . The receiver input has a fail-safe feature thatguarantees a logic-high output if the input is open circuit .

The MAX487 and MAX1487 feature quarter-unit-loadreceiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus . Full-duplex communications are obtained using the MAX488–MAX491, whilethe MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications .
