6.3 TolerANT Technology Electrical Characteristics
The LSI53C876 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.

Note:
TolerANT applies only to the SCSI bus.
