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 o
