FEATURES  
DESCRIPTION  
The LMS485 is a low power differential bus/line  
transceiver designed for high speed bidirectional data  
communication on multipoint bus transmission lines.  
It is designed for balanced transmission lines. It  
meets ANSI Standards TIA/EIA RS422-B, TIA/EIA  
RS485-A and ITU recommendation and V.11 and

X.27. The LMS485 combines  
a
TRI-STATE  
Low Power BiCMOS  
differential line driver and differential input receiver,  
both of which operate from a single 5.0V power  
supply. The driver and receiver have an active high  
and active low, respectively, that can be externally  
connected to function as a direction control. The  
driver and receiver differential inputs are internally  
connected to form differential input/output (I/O) bus  
ports that are designed to offer minimum loading to  
Allows Up To 32 Transceivers on the Bus  
Open Circuit Fail-Safe for Receiver  
Extended Operating Temperature Range −40°C

Drop-In Replacement to MAX485  
Available in 8-pin SOIC and 8-Pin DIP Package  
bus whenever the driver is disabled or when VCC  
=
0V. These ports feature wide positive and negative  
common mode voltage ranges, making the device  
suitable for multipoint applications in noisy  
environments. The LMS485 is available in a 8-Pin  
SOIC and 8-Pin DIP packages. It is a drop-in socket  
replacement to Maxim’s MAX485
