SP3485 3.3V低功耗半双工RS-485收发器，10Mbps数据传输速率
The SP3481 and the SP3485 are a family of +3.3V low power half-duplex transceivers that meet the specifications of the RS-485 and RS-422 serial protocols. These devices are pin-to- pin compatible with the Exar SP481, SP483, and SP485 devices as well as popular industry standards. The SP3481 and the SP3485 feature Exar's BiCMOS process, allowing low power operation without sacrificing performance. The SP3481 and SP3485 meet the electrical specifications of RS-485 and RS-422 serial protocols up to 10Mbps under load. The SP3481 is equipped with a low power Shutdown mode.
