SP483E - Enhanced Low EMI Half-Duplex RS-485 Transceiver

General Description

The SP483E 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.

Key Features

  • Sipex's BiCMOS design allowing low power operation without sacrificing performance. The SP483E meet the requirements of the RS-485 and RS-422 protocols up to 250kbps under load. TheSP483E is internally slew rate limited to reduce EMI and can meet the requirements of RS-485 and RS-422 up to 250kbps. The SP483E is also equipped with a low power Shutdown mode.
