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
these devices to over +15kV for both Human Body Model and IEC61000-4-2 Air Discharge
Method. This devices is pin-to-pin compatible with Exar's SP483 device as well as popular
industry standards. As with the original versions, the SP483E feature Exar's BiCMOS de-
sign allowing low power operation without sacrificing performance. The SP483E 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.
