Overview
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 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 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 suppl...
