Series Termination In practice, the resistor (R) can be omitted at the buffer output because impedance matching is difficult to achieve due to its dynamic impedance change with frequency. Advantages...
Let's talk about "fake" today
Have you ever wondered: the circuit cannot be debugged, "I may have bought a fake chip"?
Do you have any doubts: Is it a problem with your circuit design or debugging?
Ha...
