FEATURES  
DESCRIPTION  
The LTC®2850, LTC2851, and LTC2852 are low power,  
20Mbps RS485/RS422 transceivers operating on 3.3V  
supplies.Thereceiverhasaone-eighthunitloadsupporting  
up to 256 nodes per bus (C, I-Grade), and a failsafe feature  
that guarantees a high output state under conditions of  
floating or shorted inputs.
