Web腳踏車騷年MAX Web6 Oct 2016 · Note that the maximum rate a shift register can go is 1 t s u ( m i n) + t p r o p ( m a x) as the D input must be stable for at least the setup time after the previous Q output has become stable. Provided the propagation delay is greater than the hold time, it can be ignored for the maximum clock rate.
