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. This device is pin-to-pin compatible with Sipex's SP483 device as well as popular
industry standards. As with the original version, the SP483E 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. 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.
