DS1487M

The DS1487M RS-485 transceiver is a versatile and robust solution for multipoint communication, adhering to the TIA/EIA RS-485 standard. With support for up to 128 transceivers on the bus, a guaranteed full load output voltage, low quiescent current, and a wide common-mode input voltage range, it excels in industrial applications. The TRI-STATE outputs, AC performance metrics, half-duplex flow-through pinout, and single 5V supply operation contribute to its efficiency and ease of integration. Additional features such as current-limiting, thermal shutdown, and compatibility with MAX1487 further enhance its reliability and usability in demanding environments. The DS1487M is a comprehensive and high-performance transceiver, well-suited for building resilient communication networks.

The DS1487 is a low-power transceiver for RS-485 and RS-422 communication. The device contains one driver and one receiver. The drivers slew rate allows for operation up to 2.0 Mbps (see Applications Information section). The transceiver presents 1⁄4 unit loading to the RS-485 bus allowing up to 128 nodes to be connected together without the use of repeaters.

The transceiver draws 200 µA of supply current when unloaded or fully loaded with the driver disabled and operates from a single +5V supply. The driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into TRI-STATE® (High Impedance state) under fault conditions. The driver guarantees a minimum of 1.5V differential output voltage with maximum loading across the common mode range (VOD3).

The receiver has a failsafe feature that guarantees a logic-high output if the input is open circuit.

The DS1487 is available in surface mount and DIP packages.
