1 / 17 page  May 2007 Rev 6 1/17 17 Order code Part number Temperature range Package Packaging ST491ACN 0 to 70 °C DIP-14 25parts per tube / 40tube per box ST491A Low power high speed RS-485/RS-422 transceiver Features ■ Low supply current: 5mA max ■ Designed for RS485 interface applications ■ -7V to 12V common mode input voltage range ■ 70mV typical input hysteresis ■ Designed for 25Mbps operation ■ Operate from a single 5V supply ■ ±4kV ESD protection ■ 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. DIP-14 www.st.com |
