2R1
Signal Termination 1. 110-ohm termination.
3R2
Signal Termination 2. 110-ohm termination.
4R3
Signal Termination 3. 110-ohm termination.
5R4
Signal Termination 4. 110-ohm termination.
6R5
Signal Termination 5. 110-ohm termination.
7VREF1
Reference Voltage 1. Must be externally connected directly to the
VREF2 pin. Must be decoupled with a 4.7 F capacitor as shown in
Figure 2.
8
GND
Ground. Signal ground; 0.0V.
9
TERMPWR2
Termination Power 2. Should be connected to the SCSI TERMPWR
line. Must be decoupled with either a 2.2 F or 4.7 F. See Figure 2.
10
NC
No Connect. Do not connect any signal to this pin.
11
R6
Signal Termination 6. 110-ohm termination.
12
R7
Signal Termination 7. 110-ohm termination.
13
R8

PD
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.
