4 Description Continued

These devices are used for long distance communications. Isolation breaks the ground loop between the communicating nodes, allowing for a much larger common mode voltage range. The symmetrical isolation barrier of each device is tested to provide 5000VRMS of isolation for 1 minute per UL 1577 between the bus-line transceiver and the logic-level interface.

The ISO14xx devices can operate from 1.71V to 5.5V on side 1 which lets the devices be interfaced with low voltage FPGAs and ASICs. The wide supply voltage on side 2 from 3V to 5.5V eliminates the need for a regulated supply voltage on the isolated side. These devices support a wide operating ambient temperature range from –40°C to 125°C.
