NMTTL Digital Isolator and NM485 Driver

Murata Power Solutions offers isolation modules that provide bi-directional communication and multiple power rails, all powered by a single 5 V supply. The NMTTLD6S5MC and NM485D6S5MC integrate either an isolated DC-DC power supply and an RS-485 or TTL transceiver. The power supply provides regulated 5 V and ±6 V isolated supplies for system use.  

The TTL module supports data rates up to 25 Mbps, and the RS-485 module driver and receiver have active high and low enables that can be tied together to provide direction control. The modules are drop-in solutions that require no external components, are SMD-compatible, and have an industrial temperature range.
