DESCRIPTION
Termination Power 1.
Should be connected to the SCSI TERMPWR
line. Must be decoupled with either a 2.2 μF or 4.7 μF. See Figure 2.
Signal Termination 1.
110-ohm termination.
Signal Termination 2.
110-ohm termination.
Signal Termination 3.
110-ohm termination.
Signal Termination 4.
110-ohm termination.
Signal Termination 5.
110-ohm termination.
Reference Voltage 1.
Must be externally connected directly to the
VREF2 pin. Must be decoupled with a 4.7 μF capacitor as shown in
Figure 2.
Ground.
Signal ground; 0.0V.
Termination Power 2.
Should be connected to the SCSI TERMPWR
line. Must be decoupled with either a 2.2 μF or 4.7 μF. See Figure 2.
No Connect.
Do not connect any signal to this pin.
Signal Termination 6.
110-ohm termination.
Signal Termination 7.
110-ohm termination.
Signal Termination 8.
110-ohm termination.
Signal Termination 9.
110-ohm termination.
Reference Voltage 2.
Must be externally connected directly to the
VREF1 pin. Must be decoupled with a 4.7 μF capacitor as shown in
Figure 2.
Power Down.
When tied low, the DS21T05 enters a power-down
mode. Contains an internal 50K pull-up. Strap low to deactivate the
DS21T05, leave open circuited to activate the DS21T05.
