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 po.
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.
