7 Parameter Measurement Information
Figure 11 and Figure 12 show the resistive-load test circuit and voltage waveforms. One can see from Figure 12
that with G held low and CLR held high, the status of each drain changes on the rising edge of the register clock,
indicating the transfer of data to the output buffers at that time.
