Continued from preceding page.
NC pins must be left open.
Pin names that start with a ‘Z’ are negative logic (i.e. active low) pins.
VSS0 is the logic system ground, and VSS1 is the SCSI interface system ground.
If DRAM is used, undershoot prevention measures, such as inserting resistors in the RAS and CAS lines and inserting capacitors to ground, must be taken.
Since this IC includes buffers that sink 48 mA, applications must take adequate noise reduction measures.
