General Description

The MAX1481/MAX1484/MAX1485/MAX1486 provide software-selectable, half-/full-duplex, low-power, slewrate-limited, and high-speed (12Mbps) RS-485/RS-422 operation in a 10-pin µMAX® package—the smallest 10-pin package available.

The software-selectable, half-/full-duplex MAX1485/ MAX1486 make obsolete the normally larger and more expensive solutions required for selectable half-/fullduplex RS-485/RS-422 operation: 1) a 14-pin, fullduplex transceiver configured via jumpers between receiver and transmitter lines, or 2) two 8-pin, halfduplex transceivers, which require an additional inverter logic gate for software selectability.

The MAX1481/MAX1484 are functionally equivalent to the industry-standard MAX491 and 75180, and are designed for space-constrained, full-duplex RS-422 applications.
