Note:
1. For +2.5V systems: R1 = 250 , R2 = 62.5
Notes:
1. Power-saving alternative to Thevenin termination.
2. Place termination resistors as close to destination inputs as possible.
3. R
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 .
2. Unused output pairs (Q and /Q) may be left floating.
