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  
(C-, I-grades), and a failsafe feature that guarantees a high  
outputstateunderconditionsoffloatingorshortedinputs.
