Figure 2. Typical Differential SCSI Bus Configuration
NOTE 1: C1 = 4.7µF TANTALUM CAPACITOR; C2 = 2.2µF TANTALUM OR 4.7µF ALUMINUM CAPACITOR.
NOTE 2: IF THE DS21S07A IS TO BE EMBEDDED INTO A PERIPHERAL THAT WILL ACT AS A TARGET
ON A SCSI BUS, IT IS RECOMMENDED THAT TERMPWR BE DERIVED FROM THE SCSI CABLE, NOT
GENERATED LOCALLY. IN THIS CONFIGURATION, IF A POWER FAILURE OCCURS IN THE
PERIPHERAL, IT WILL NOT AFFECT THE BUS.
NOTE 3: A HIGH-FREQUENCY BYPASS CAPACITOR (0.1µF RECOMMENDED) CAN BE ADDED IN
PARALLEL TO C1 FOR APPLICATIONS USING FAST RISE/FALL TIME DRIVERS.
