UCC5638 15 线路 2.7-5V 多模端接器，用于 SCSI 至 Ultra320 SCSI
The UCC5638 Multimode SCSI Terminator provides a smooth transition into the LVD SCSI Parallel Interface (SPI-2, SPI-3, 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 UCC5638 can not be used on a HVD, EIA485, differential SCSI bus. If the UCC5638 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 and Differential impedances and currents are trimmed for maximum effectiveness
