ST485  
Low power  
RS-485/RS-422 transceiver  
General features  
I Low quiescent current: 300mA  
I Designed for RS-485 interface application  
I -7V to 12V common mode input voltage range  
I Driver maintains high impedance in 3-state or  
with the power OFF  
I 70mV tipycal input hysteresis  
I 30ns propagation delay, 5ns skew  
I Operate from a single 5V supply  
DIP-8  
SO-8  
I Current limiting and thermal shutdown for  
driver overload protection  
I Allows up to 64 transceivers on the bus  
Description  
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.  
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 designed for bi-directional data  
communications on multipoint bus transmission  
line (half-duplex applciations).  
This transceiver draw 300mA (typ.) of supply  
current when unloaded or fully loaded with  
disabled drivers.  
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)  
It operates from a single 5V supply.
