FEATURES  
DESCRIPTION  
The LTC®2859 and LTC2861 are low power, 20Mbps  
RS485/422 transceivers operating on 5V supplies. The  
receiver includes a logic-selectable 120Ω termination,  
one-eighth unit load supporting up to 256 nodes per bus,  
and a failsafe feature that guarantees a high output state  
under conditions of floating or shorted inputs.
