LSI53C825A Host Interface Data Paths
The LSI53C825A supports both SE and differential operation.
All SCSI signals are active LOW. The LSI53C825A contains the SE
output drivers and can be connected directly to the SCSI bus. Each
output is isolated from the power supply to ensure that a powered-down
LSI53C825A has no effect on an active SCSI bus (CMOS “voltage
feed-through” phenomena). TolerANT technology provides signal filtering
at the inputs of SREQ/ and SACK/ to increase immunity to signal
reflections.
