The DS2108 SCSI Terminator has been specifically designed for High Voltage Differential (HVD) SCSI systems requiring switchable termination. The DS2108 integrates eighteen 330-ohm and nine 150-ohm precise switched termination resistors into a monolithic IC. The surface mount SOIC package saves board space over conventional resistor SIPs. The termination resistors can be isolated from the SCSI bus under software or hardware control. While in the powered down mode, the DS2108 isolates the nine terminator blocks from the bus while adding only 6 pF capacitance to each signal line of the SCSI bus.
