... TERMPWR decoupling, and very low quiescent current consumption. The DS21S07A integrates a reg- ulator and nine precise switched 110 ohm termination resistors into a monolithic IC. The DS21S07A can be electrically isolated from the SCSI bus without physical removal from the SCSI device. 022798 1/7 ...

... C1 = 4.7 F tantalum C2 = 2.2 F tantalum or 4.7 F aluminum 2. If the DS21S07A embedded into a peripheral that will act as a target on a SCSI bus that recom- mended TERMPWR be derived from the SCSI cable, not generated locally. In this configuration power failure occurs in the peripheral, it will not affect the bus. ...
