NOTES:

1. C1 = 0.1µF ceramic

C2 = 4.7µF tantalum

C3 = 2.2 µF tantalum or 4.7 µF aluminum

2. If the DS2107A 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.
