Analog Devices offers one of the highest ESD rated RS-422, RS-485, and Profibus transceivers in the industry. By integrating this protection function into the same package as the transceiver, designers save more than 50% PC board space eliminating the need for external protection diodes, saving components, warehousing, and placement costs. As shown in this slide, two TVS diodes in SMB packages, which are the most common package size, are no longer needed. The protection level of Analog Devices' transceivers are typically two to three times what other suppliers have.
