SSP485N

The SSP485N is a half- duplex high speed transceiver for RS- 485 communication. IC contains one driver and one receiver, It has adaptive function. The SSP485N has a fail- safe circuit, ensure logical high level of receiver output when receiver input is open or short. The SSP485N receiver has 1/8 unit load input impedance, allows up to 256 devices can be attached to the bus. The SSP485N is a half- duplex high speed transceiver for RS- 485 communication. IC contains one driver and one receiver. It has adaptive function, AB terminal reverse connection can also communicate normally. The SSP485N receiver has 1/8 unit load input impedance, allows up to 256 devices can be attached to the bus.
