The sixteen pulses generator circuit which is composed of the SN74123 is as shown in the figure. When you input the negative pulse starting signal, it will produce the 1.2μS sixteen pulses, and the negative edge of the pulse controls the end of the counting, so we get the output of the counter. If you decode the output of the counter and use the pulse as the timing, so you can control the order of synchronous circuit. The figure 6-40(a) shows the practical circuit, it is composed of the multivibrator which is composed of the SN74123 and SN7476, the counter which is composed of the SN74161, the start/stop control part of the counter.
