The UCC5629 multimode SCSI terminator provides a smooth transition into the low-voltage differential (LVD) SCSI parallel interface (SPI2, SPI3, SPI4). It automatically senses the bus, via DIFFB, and switches the termination to either single-ended (SE) or low-voltage differential (LVD) SCSI, dependent on which type of devices are connected to the bus. The UCC5629 can not be used on a HVD, EIA485, differential SCSI bus. If the UCC5629 detects a HVD SCSI device, it switches to a high-impedance state.
