DESCRIPTION  
The ST490A is a low power transceiver for  
RS-485 and RS-422 communications. The device  
contains one driver and one receiver in full duplex  
configuration. The ST490A draws 5mA (typ.) of  
supply current when unloaded or fully loaded with  
disabled drivers. It operates from a single 5V  
supply.  
Driver is short-circuit current limited and is  
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.
