Product Summary

The SP483EEP is an Enhanced Low EMI Half-Duplex RS-485 Transceiver. 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. This device is pin-to-pin compatible with Sipex’s SP483 device as well as popular industry standards. As with the original version, the SP483EEP features Sipex’s BiCMOS design allowing low power operation without sacrificing performance. The SP483EEP meet the requirements of the RS-485 and RS-422 protocols up to 250kbps under load. The SP483EEP is internally slew rate limited to reduce EMI and can meet the requirements of RS-485 and RS-422 up to 250kbps. The SP483EEP is also equipped with a low power Shutdown mode.
