MaxLinear | SP485ECN-L/TR

The SP481E and the SP485E are 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 +15KV for both Human Body Model and IEC1000-4-2 Air Discharge Method.

The SP481E and the SP485E are pin-to-pin compatible with Exar's SP481 and SP485 devices as well as popular industry standards. As with the original versions, the SP481E and the SP485E feature Exar's 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.

In telecommunications, RS485 is an electrical specification of a two-wire,[1] half-duplex, multipoint serial communications channel. Since it uses a differential balanced line over twisted pair (like RS-422), it can span relatively large distances (up to 4,000 feet (1,200 m)).
