ST490AB

低功耗全双工高速RS-485/RS-422收发器，温度范围[-40℃, 85℃]; • Current limiting and thermal shutdown for driver overload protection \n• ±4 kV ESD protection \n• Low supply current: 5mA max \n• 70mV typical input hysteresis \n• -7V to 12V common mode input voltage range \n• Operate from a single 5 V supply \n• Designed for 25Mbps operation;

The ST490A is a low power transceiver for RS485 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. \n\n 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. \n\n
