LX5240CDB中文资料美高森美数据手册PDF规格书

DESCRIPTION

The LX5240 is a multimode SCSI terminator with plug-and-play capability that conforms to the SCSI Parallel Interconnect-2 (SPI-2) specification 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.
