Output Interface Applications
Notes:
1. For +2.5V systems: R1 = 250Ω, R2 = 82.5Ω.
2. For +5.0V systems: R1 = 82Ω, R2 = 130Ω.
Notes:
1. Power-saving alternatives 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 = 250Ω, R2 = 62.5Ω, R3 = 1.25kΩ, R4 = 1.2kΩ.
