概述

完整的数据资料 (PDF, 604kB) 英文 下载 The MAX1482 and MAX1483 are low-power transceivers for RS-485 and RS-422 communication. Both feature slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables. Data rates are guaranteed up to 250kbps. The MAX1482/MAX1483 draw only 20µA of supply current. Additionally, they have a low-current shutdown mode that consumes only 0.1µA. Both parts operate from a single +5V supply. 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 the input is open circuit. The MAX1482 is full duplex and the MAX1483 is half duplex. Both parts have a 1/8-unit-load input impedance that guarantees up to 256 transceivers on the bus.
