Mouser offers Murata’s NM485D6S5MC isolated RS485 driver

Distributor, Mouser Electronics, now stocks the NM485D6S5MC isolated RS485 driver DC/DC from Murata Power Solutions.

The driver is engineered for bi-directional data communication or multi-point bus transmission. The low-power, electrically isolated TTL data transmission NM485D6S5MC powers system circuitry through three power options. It provides an unregulated 6V supply, a -6V isolated supply, or a regulated 5V supply, which can eliminate the need for external components and supply all the functions on both sides of the isolation boundary.

The Murata NM485D6S5MC isolated RS485 driver is an EIA-485-compatible differential communications interface that enables data transmission at high rates over long distances. The built-in, tri-state differential line driver and differential input line receiver both have active high and active low enable pins, allowing the device to be connected together to function as a direct control, says Mouser. This means the device can receive when the receiver enable pin is low and transmit when the driver enable pin is high. As the driver is active high, to reduce the power dissipation even further, designers can simply disable the driver when it is not transmitting data.

The NM485D6S5MC provides a 500kbit/s data rate and has been tested at 3000 VACRMS hi-pot test. It features current limiting and thermal shutdown as well as short circuit protection at ambient temperatures down to -40 degrees C. The SMD/SMT NM485D6S5MC driver complies with ANSI TIA/EIA RS-485-A-1998 and ISO 8482: 1987(E) specifications, and offers a compact, low-power solution for a wide range of half-duplex and full-duplex RS-485 computer and industrial serial interfacing and network configuration applications.

Mouser strives to empower innovation among design engineers and buyers by delivering advanced technologies. The distributor claims to stock the world’s widest selection of the latest semiconductors and electronic components for the newest design projects. Its website is continually updated and offers advanced search methods to help customers quickly locate inventory. It is also the place to find data sheets, supplier-specific reference designs, application notes, technical design information, and engineering tools.
