Unused ("NC") pins must be left open.
Pins whose name is under a bar operate with inverted (negative) logic.
VSS0 is the logic system ground and VSS1 is the SCSI interface driver ground.
Since this device includes buffers that sink a current of 48 mA, applications must take adequate noise prevention measures.
