PROTECTION  
DIP  
SOP  
It operates from a single 5V supply.  
ALLOWS UP TO 64 TRANSCEIVERS ON  
THE BUS  
Driver is short-circuit current limited and is  
protected against excessive power dissipation by  
thermal shutdown circuitry that placed the driver  
outputs into a high-impedance state. .  
DESCRIPTION  
The ST485 is designed for bi-directional data  
communications on multipoint bus transmission  
line (half-duplex applciations).  
The ST485 is al low power transceiver for RS-485  
and RS-422 communication. Each part contains  
one driver and one receiver.  
The ST485 is available in three temperature  
range: commercial (0°C to 70°C), industrial (-40°C  
to 850°C) and automotive (-55°C to 125°C)  
This transceiver draw 300µA (typ.) of supply  
current when unloaded or fully loaded with  
disabled drivers.
