Separate logic supply pin eliminates the need for an additional level shifter when the MCU and RS-485 transceivers are operating with different supplies. The bus pins are immune to high levels of IEC Contact Discharge ESD events eliminating the need for additional system level protection components. The wide common-mode voltage range and low input leakage on bus pins makes the device suitable for multi-point applications over long cable runs.

THVD1400V is available in space-saving thermally efficient 10-VSON package (3 mm x 3 mm). The device is characterized for ambient temperature from –40°C to 125°C.
