Description
The DS2108 integrates 18 330-ohm and nine 150-ohm precisely switched resistors for terminating nine high-voltage differential (HVC) SCSI pairs of lines and includes a power-down feature. The power-down can be switched via software, which is simpler than opening the box to switch it manually. The 24-pin SOIC saves board space for space-critical applications.
SCSI termination is used wherever data must be transmitted without voltage drops caused by signal reflection at the parallel bus termination point, which is often significant in multidropped systems.
All Dallas terminators feature power-down mode with extremely low-quiescent consumption. Different SCSI terminators are available to match every existing SCSI protocol and to address different design concerns, such as price, board space, and voltage differential.
