产品概述

The MAX1482 and MAX1483 are low-power transceiversfor RS-485 and RS-422 communication. Bothfeature slew-rate-limited drivers that minimize EMI andreduce reflections caused by improperly terminatedcables. Data rates are guaranteed up to 250kbps.

The MAX1482/MAX1483 draw only 20µA of supply current.Additionally, they have a low-current shutdownmode that consumes only 0.1µA. Both parts operatefrom a single +5V supply.

Drivers are short-circuit current limited and are protectedagainst excessive power dissipation by thermalshutdown circuitry that places the driver outputs into ahigh-impedance state. The receiver input has a fail-safefeature that guarantees a logic-high output if the inputis open circuit.
The MAX1482 is full duplex and the MAX1483 is halfduplex. Both parts have a 1/8-unit-load input impedancethat guarantees up to 256 transceivers on the bus.
