DS485 Low Power RS-485/RS-422 Multipoint Transceiver July 1998 DS485 Low Power RS-485/RS-422 Multipoint Transceiver General Description The DS485 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 2.5 Mbps (see Applications Information section). 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.
