DESCRIPTION
The SP3483 device is part of a family of +3.3V low power half-duplex transceivers that meet
the specifications of the RS-485 and RS-422 serial protocols. This device is pin-to-pin
compatible with the Sipex SP483 device as well as popular industry standards. The SP3483
features Sipex's BiCMOS process, allowing low power operation without sacrificing
performance. The SP3483 is internally slew rate limited to reduce EMI and can meet the
requirements of RS-485 and RS-422 up to 250kbps.
