FEATURES  
DESCRIPTIO  
The LTC®1481 is an ultralow power differential line trans-  
ceiver designed for data transmission standard RS485  
applications. It will also meet the requirements of RS422.

Ground Difference Between Devices on the Data Line  
The driver and receiver feature three-state outputs, with  
the driver outputs maintaining high impedance over the  
entire common mode range. Excessive power dissipation  
caused by bus contention or faults is prevented by a  
thermal shutdown circuit which forces the driver outputs  
into a high impedance state. The receiver has a fail-safe  
feature which guarantees a high output state when the  
inputs are left open.
