... Active termination provides greater immunity to voltage drops on the TERMPWR (TERMination PoWeR) line, enhanced high-level noise immunity, intrinsic TERMPWR decoupling, and very low quiescent current consumption. One DS21T06 can be used to terminate the Narrow SCSI bus DS21T07 can be used with a DS21T06 for termination of a Wide SCSI bus. ...

... Figure 2 details a typical SCSI bus configuration 8-bit data SCSI bus (Narrow SCSI), one DS21T06 is needed for proper termination of the 18 active signal lines. One DS21T06 and one DS21T07 can be used to terminate the 27 active signal lines in a 16- bit data SCSI bus (Wide SCSI). ...

... C2 = 2.2 F tantalum or 4.7 F aluminum C3 = 0.01 F ceramic 2. If the DS21T06 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. ...

... GND DESCRIPTION Power Down. When tied low, the DS21T06 enters power-down mode. Contains an internal 50 kΩ pull-up. Tie low to deactivate the DS21T06. Tie high or leave open circuited to activate the DS21T06. Signal Termination 1. 110 ohms termination. Connect to SCSI bus signal lines. Heat Sink Ground. Internally connected to the mounting pad. Should be either grounded or electrically isolated from other circuitry ...
