TYPICAL DIFFERENTIAL SCSI BUS CONFIGURATION
Figure 2
NOTES:
1.
Two DS2108s required per 8–bit SCSI device and three DS2108s per 16–bit SCSI device.
2.
Mid–bus termination effectively removed by grounding
PD
pin.
3.
Termination power to be provided as specified in SCSI–3 Parallel Interface (SPI) document.
4.
Local TERMPWR bypassing is recommended by the SPI document with values shown. The bypass
capacitors should be located as close as possible to the DS2108s. Only one pair of capacitors is
required per SCSI device (may be shared between DS2108s on same device).

Power Down.
When tied low, the DS2108 enters a power-down mode.
Contains an internal 50K pull-up. Strap low to deactivate the DS2108,
leave open circuited to activate the DS2108.
