SSP3485
The SSP3485 is a half-duplex high speed transceiver for RS-485 and RS422 communication. IC contains one driver and one receiver.
The SSP3485 has a fail-safe circuit. It has a slew-rate-limited driver that reduces EMI and reflection due to improperly matched terminal cables, and achieves error-free data transmission of up to 10Mbps. Each driver output and receiver input is protected against ±15kV electrostatic discharge (HBM) (ESD)shocks.
The SSP3485 receiver has 1/8 unit load input impedance, allows up to 256 devices can be attached to the bus. Mainly used in RS-485/RS-422 communication system.
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.
