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.
■ LOW SUPPLY CURRENT: 5mA MAX
■ DESIGNED FOR RS485 INTERFACE APPLICATIONS
■ -7 TO 12 COMMON MODE INPUT VOLTAGE RANGE
■ 70mV TYPICAL INPUT HYSTERESIS
■ DESIGNED FOR 25Mbps OPERATION
■ OPERATE FROM SINGLE 5 SUPPLY
■ ±4kV ESD PROTECTION
■ CURRENT LIMITING AND THERMAL SHUTDOWN FOR DRIVER OVERLOAD PROTECTION
