The software-selectable, half-/full-duplex MAX1485/ MAX1486 make obsolete the normally larger and more expensive solutions required for selectable half-/full- duplex RS-485/RS-422 operation: 1) a 14-pin, full- duplex transceiver configured via jumpers between receiver and transmitter lines, or 2) two 8-pin, half- duplex transceivers, which require an additional invert- er 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. All parts contain one driver and one receiver and fea- ture a 1/8-unit-load receiver input impedance, allowing up to 256 transceivers on the bus. The MAX1481/ MAX1485 feature reduced-slew-rate drivers that mini- mize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. The MAX1484/MAX1486 driver slew rates are not limited, allowing them to transmit up to 12Mbps. The MAX1481/MAX1484/MAX1485/MAX1486 draw only 300µA of supply current. The MAX1481 has a low-power shutdown mode that reduces supply current to only 0.1µA. All devices operate from a single 5V supply. Drivers are output 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. ____________________________Features o 10-Pin µMAX Package: Smallest 10-Pin Package o Software-Selectable Half-/Full-Duplex Operation (MAX1485/MAX1486) o 0.1µA Low-Current Shutdown Mode (MAX1481) o Slew-Rate Limiting Allows Error-Free Data Transmission (MAX1481/MAX1485) o 12Mbps High-Speed Operation (MAX1484/MAX1486) o Allow up to 256 Transceivers on the Bus ________________________Applications Low-Power RS-422/RS-485 Communications Level Translators Hand-Held Equipment Battery-Powered Equipment Transceiver for EMI-Sensitive Applications Industrial-Control Local Area Networks Software-Selectable, Half-/Full-Duplex, Slew-Rate-Limited, 12Mbps, RS-485/RS-422 Transceivers in µMAX Package ________________________________________________________________ Maxim Integrated Products 1 19-1312; Rev 0; 10/97 PART MAX1481CUB MAX1481EUB MAX1484CUB 0°C to +70°C -40°C to +85°C 0°C to +70°C TEMP.
