The SP1485E is a half-duplex transceiver that meets the specifications of RS-485 and RS-
422 serial protocols with enhanced ESD performance. The ESD tolerance has been improved
on this device to over +15KV for both Human Body Model and IEC1000-4-2 Air Discharge
Method. This device is pin-to-pin compatible with Sipex's SP485 devices as well as popular
industry standards. As with the original version, the SP1485E features Sipex's BiCMOS
design allowing low power operation without sacrificing performance. The SP1485E meets
the requirements of the RS-485 and RS-422 protocols up to 20Mbps under load.
