SP1481E Datasheet | Sipex

DESCRIPTION The SP1481E is a half-duplex transceiver that meets the specifications of RS-485 and RS422 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 patible with Sipex's SP485 and SP481 devices as well as popular industry standards. As with the original version, the SP1481E features Sipex's Bi CMOS design allowing low power operation without sacrificing performance. The SP1481E meets the requirements of the RS-485 and RS-422 protocols up to 20Mbps under load.
