1. These values are guaranteed by periodic characterization; they are not 100% tested on every device.
2. Active negation outputs only: Data, Parity, SREQ/, SACK/. (Minus Pins) SCSI mode only.
3. Single pin only; irreversible damage may occur if sustained for more than one second.
4. SCSI RESET/ pin has 10 k

pull-up resistor.
