The NM485D6S5MC from Murata Power Solutions is an isolated DC/DC RS485 driver. It is a low power electrically isolated differential driver and receiver which is designed for bi-directional data communication or multipoint bus transmission. The device combines a tristate differential line driver and a differential input line receiver. The driver and receiver have active high and active low enables respectively which can be connected together to function as direction control. No external components are needed as a single 5V supply powers all functions either side of the isolation boundary. NM485D655MC also provides a regulated 5V, unregulated 6V and -6V isolated supply"s for system use. Complies with ANSI TIA/EIA RS-485-A-1998 and ISO 8482: 1987(E) standards.
