The ISO1500 device is a galvanically-isolated differential line transceiver for TIA/EIA RS-485 and RS-422 applications. This device has a 3-channel digital isolator and an RS-485 transceiver in an ultra-small 16-pin SSOP package. The bus pins of this transceiver are protected against IEC ESD contact discharge and IEC EFT events. The receiver output has a failsafe for bus open, short, and idle conditions. The small solution size of ISO1500 greatly reduces the board space required compared to other integrated isolated RS-485 solutions or discrete implementation with optocouplers and non-isolated RS-485 transceiver.

The device is 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 3000 VRMS of isolation for 1 minute per UL 1577 between the bus-line transceiver and the logic-level interface.

The ISO1500 device can operate from 1.71 V to 5.5 V on side 1 which lets the devices interface with low-voltage FPGAs and ASICs. The supply voltage on side 2 is from 4.5 V to 5.5 V. This device supports a wide operating ambient temperature range from –40°C to +125°C.
