In the typical application example shown, the SA A10 42 drives a 12V stepper
motor with a phase winding current of 200mA. Select Figure 5-10 from RB and take RE=56kfl.
It is connected to the MC14007 NOT gate output. The clock in Figure 5-9 is
generated by a phase-locked frequency synthesizer composed of MC14046 and MC14024. The step clock
can be selected in seven levels of 12. 5- SOOHz.
