UCC5628 14 线路 2.7-5V 多模端接器，用于 SCSI 至 Ultra320 SCSI
The UCC5628 Multimode SCSI terminator provides a smooth transition into the low-voltage differential SCSI parallel interface (SPI-2, SPI-3 and SPI-4). 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 UCC5628 can not be used on a high voltage differential (HVD), EIA485, differential SCSI bus. If the UCC5628 detects a HVD SCSI device, it switches to a high-impedance state.
The Multimode terminator contains all functions required to terminate and auto detect and switch modes for SPI-2, SPI-3 and SPI-4 bus architectures. Single ended, differential impedances and currents are trimmed for maximum effectiveness
