TYPICAL SCSI BUS CONFIGURATION Figure 2
NOTES:
1. C1 = 4.7 F tantalum
2. If the DS2105 is to be embedded into a peripheral that will act as a target on a SCSI bus, it is recommended that
3. A high frequency bypass capacitor (0.1 F recommended) can be added in parallel to C1 for applications using
C2 = 2.2 F tantalum or 4.7 F aluminum
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.
