Note:
1. For +5.0V systems: R1 = 82Ω, R2 = 130Ω.
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. Micrel's differential I/O logic devices include a V
3. Connect unused input through 50Ω to V
