SK2485

The SK2485 is high- speed transceivers for RS- 485 communication, which contain one driver and one receiver. The SK2485 feature fail- safe circuitry, which guarantees a logic- high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). The SK2485 driver slew rates are not limited, making transmit speeds up to 10Mbps possible. And this device has a 1/8- unit- load receiver input impedance that allows up to 256 transceivers on the bus.
