DESCRIPTION

The LX5241/42/43 is a multimode SCSI terminator that is compatible with to the SCSI SPI02 (Ultra2 SCSI), SCSI SPI-3 (Ultra3 SCSI or Ultra160 SCSI), and pending SCSI SPI-4 (Ultra320) specifications developed by the T10 standards committee for low voltage differential (LVD) termination, while providing backwards compatibility to the SCSI, SCSI-2, and SPI single ended specifications. Multimode compatibility permits the use of legacy devices on the bus without hardware alterations. Automatic mode selection is achieved through voltage detection on the Diffsense line.
