DS481 Low Power RS-485/RS-422 Multipoint Transceiver with Sleep Mode July 1998 DS481 Low Power RS-485/RS-422 Multipoint Transceiver with Sleep Mode General Description The DS481 is a low-power transceiver for RS-485 and RS-422 munication. 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 draws 200 µA of supply current when unloaded or 0.2 µA when in the automatic sleep mode. Sleep mode is activated by inactivity on the enables (DE and RE (Note 1)). Holding DE = L and RE (Note 1) = H for greater than 600 ns will enable the sleep mode. The DS481 operates from a single +5V...
