Output Interface Applications
Figure 1. Parallel Termination-Thevenin Equivalent
Notes:
1. For +2.5V systems: R1 = 250, R2 = 82.5.
Figure 2. Three-Resistor “Y-Termination
Notes:
1. Power-saving alternatives to Thevenin termination.
2. Place termination resistors as close to destination inputs as possible.
3. For +2.5V systems, R
b
= 19. R
b
resistor sets the DC bias voltage, equal to V
t
.
Figure 3. Terminating Unused I/O
Notes:
1. Unused output (/Q) must be terminated to balance the output.
2. For 2.5V systems: R1 = 250, R2 = 62.5, R3 = 1.25k, R4 = 1.2k.
