ST485A  
Very high speed  
low power RS-485/RS-422 transceiver  
General features  
Low supply current: 5mA max  
High data rate > 30Mbps  
Designed for RS 485 interface applications  
-7 to 12 common mode input voltage range  
Driver maintains high impedance in 3-state or  
with the power off  
70mV typical input hysteresis  
Operate from single 5 supply  
±4kV ESD protection  
DIP-8  
SO-8  
Driver is short-circuit current limited and is  
Current limiting and thermal shutdown for  
protected against excessive power dissipation by  
thermal shutdown circuitry that place the driver  
outputs into a high-impedance state. The receiver  
input has a fail-safe feature that guarantees a  
logic high output if both inputs are open circuit.  
driver overload protection  
Latch-up free up to 500mA  
Description  
The ST485A is designed for bi-directional data  
communications or multipoint bus transmission  
lines.  
The ST485A is a low power, high speed  
transceiver for RS-485 and RS-422  
communications. The device contains one driver  
and one receiver in half duplex configuration. The  
ST485A draws 3mA (typ.) of supply current when  
unloaded or fully loaded with disabled drivers. It  
operates from a single 5V supply.
