Low supply current: 5mA max High data rate 30Mbps Designed for RS 485 interface applications -7 to 12 common mode input voltage range Driver maintains high impedance in 3-state or with the power off 70mV typical input hysteresis Operate from single 5 supply ±4kV ESD protection Current limiting and thermal shutdown for driver overload protection Latch-up free up to 500mA 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 ...
