The SS7500 provides backward compatibility to the SCSI and SCSI-2 specifications. Multimode function sets up the use of legacy devices on the bus without changing any hardware setting. Automatic selection is made by voltage detection on the diffsense line. If the device is connected to an LVD-only bus, the SS7500 will use LVD termination. If the device is connected in a Single Ended mode, the SS7500 will be connected in a SE termination. The SCSI termination architecture uses high speed elements for the design, therefore providing fast response time.
