DESCRIPTION
The SP481E and SP485Eare a family of half-duplex transceivers that meet the specifications of RS-485 and RS-422 serial protocols with enhanced ESD performance. The ESD tolerance has been improved on these devices to over +5kV for both Human Body Model and IEC1000-4-2 Air Discharge Method. These devices are pin-to-pin compatible with Exars SP481 and SP485 devices as well as popular industry standards. As with the original versions, the SP481E and SP485E feature Exars BiCMOS design allowing low power operation without sacrificing performance. The SP481E and SP485E meet the requirements of the RS-485 and RS-422 protocols up to 10Mbps under load. The SP481Eis equipped with a low power shutdown mode.
