... TERMPWR decoupling, and very low quiescent current consumption. The DS2114 integrates a regulator and nine precise 110 ohms termination re- sistors into a monolithic IC. The DS2114 is intended for cable end terminator assemblies and devices where the terminators do not need to be isolated from the SCSI bus ...

... C1 = 4.7 F tantalum C2 = 2.2 F tantalum or 4.7 F aluminum 2. If the DS2114 embedded into a peripheral that will act as a target on a SCSI bus recommended that 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. ...

... Exposure to absolute maxi- mum rating conditions for extended periods of time may affect reliability. The Dallas Semiconductor DS2114 is built to the highest quality standards and manufactured for long term reliability. All Dallas Semiconductor devices are made using the same quality materials and manufacturing methods. However, the DS2114 is not exposed to environmental stresses, such as burn– ...
