The LTC®1485 is a low power differential bus/line trans-  
ceiverdesignedformultipointdatatransmissionstandard  
RS485 applications with extended common-mode range  
(12V to –7V). It also meets the requirements of RS422.  
■
■
■
The CMOS with Schottky design offers significant power  
savings over its bipolar counterpart without sacrificing  
ruggedness against overload or ESD damage.  
■
■
■
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. I/O pins are protected against  
multiple ESD strikes of over ±10kV.  
■
■
■
Pin Compatible with the SN75176A, DS75176A, and  
SN75LBC176  
The receiver has a fail-safe feature which guarantees a  
high output state when the inputs are left open.
