SN75LVDM977 Overview
The SN75LVDM976 and SN75LVDM977 have nine transceivers for transmitting or receiving the signals to or from a SCSI data bus. They offer electrical patibility 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.
