1 / 12 page 1/12 July 2003 s LOW SUPPLY CURRENT: 5mA MAX s DESIGNED FOR RS485 INTERFACE APPLICATIONS s -7 TO 12 COMMON MODE INPUT VOLTAGE RANGE s 70mV TYPICAL INPUT HYSTERESIS s DESIGNED FOR 25Mbps OPERATION s OPERATE FROM SINGLE 5 SUPPLY s ±4kV ESD PROTECTION s CURRENT LIMITING AND THERMAL SHUTDOWN FOR DRIVER OVERLOAD PROTECTION DESCRIPTION The ST491A 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 ST491A draws 5mA (typ.) of supply current when unloaded and 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.
