9-Channel LVD-SCSI Transceiver 56-SSOP 0 to 70

The SN75LVDM976 and SN75LVDM977 have nine transceivers for transmitting or receiving the signals to or from a SCSI data bus. They offer electrical compatibility to both the single-ended signaling of X3.277:1996-SCSI-3 Parallel Interface (Fast-20) and the new low-voltage differential signaling method of proposed standard 1142-D SCSI Parallel Interface - 2 (SPI-2). The differential drivers are nonsymmetrical. The SCSI bus uses a dc bias on the line to allow terminated fail safe and wired-OR signaling. This bias can be as high as 125 mV and induces a difference in the high-to-low and low-to-high ...
