The stepper motor driver circuit is using a pair of TEA3718/3717 to drive the stepper motor in bipolar chopper configuration. The U3 555 timer provides the clock pulse. The U1 and U2 form a two-direction TTL full step generator. If only one direction is needed then the circuit below can be used.

An extended TTL generator, which can generate control signals for full step and half step is shown in Figure 2.
