SP481E - Enhanced Low Power Half-Duplex RS-485 Transceivers

General Description

The SP481E and 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 IEC61000-4-2 Air Discharge Method.
