DESCRIPTION
The SP3493 and the 3494 devices are +3.3V, low power transceivers that meet the
specifications of the RS-485 and RS-422 serial protocols. The SP3493 and the 3494 devices
are pin-to-pin compatible with the Sipex SP3490 and the SP3481 devices, respectively, as well
as other popular industry standards. The devices feature Sipex's BiCMOS process, allowing
low power operation without sacrificing performance. The partially slew-rate limited drivers
minimize EMI and reduce reflections caused by improperly terminated cables allowing
error-free data transmission. The SP3493 is a full-duplex low power transceiver that will
deliver a data transmission rate up to 250kbps. The SP3494 is a half-duplex partially slew-rate
limited transceiver that will deliver a data transmission rate up to 2.5Mbps. The SP3494 is
equipped with a low-power shutdown mode and driver/receiver high-Z enable lines.
