The ISOW308x devices are isolated RS-485/RS-422 transceivers with a built-in isolated DC-DC converter, that eliminates the need for a separate isolated power supply in space constrained isolated designs. The low-emissions, isolated DC-DC converter meets CISPR 32 radiated emissions Class B standard on a simple two-layer PCB.

Two options of data rates are provided: ISOW3080 is optimized for maximum 500kbps and ISOW3086 is designed for maximum 12Mbps data rate. These devices do not require any external components other than supply decoupling capacitors to realize an isolated RS-485 port, best for long distance communications. Isolation breaks the ground loop between the communicating nodes, allowing for a much larger common mode voltage range. Both signal and power paths are 5kVRMS isolated per UL1577 and are qualified for reinforced and basic isolation per VDE, TUV and CQC. The bus pins of these devices can endure up to 16kV of HBM stress.

The ISOW308x can operate from a single supply voltage of 3V to 5.5V by connecting VDDL and VDD together on PCB. If lower logic levels are required, 2.25V to 5.5V logic supply (VDDL) can be separated and independent from the power converter supply (VDD) of 3V to 5.5V. These devices support a wide operating ambient temperature range from –55°C to +125°C and are available in 16-pin DWE (SOIC-16 footprint compatible package) offering a minimum of 8mm creepage and clearance.
