TolerANT Technology Electrical Characteristics for SE SCSI Signals
The LSI53C040 features TolerANT technology, which includes active
negation on the SCSI drivers and input signal filtering on the SCSI
receivers. Active negation actively drives the SCSI Request,
Acknowledge, Data, and Parity signals HIGH rather than allowing them
to be passively pulled up by terminators.
characteristics for SE SCSI signals.
