input voltages pairs applied input respectively. When input voltages applied input #14, then output comparator decided depends input voltage status. shown above diagram, difference voltage, applied both terminals motor. direction motor decided voltage difference, output characteristics follows, 9=5V #14=0V, then 15=+V #16= hence motor turn forward direction. 9=0V #14=5V, then #16=+V, hence motor turn reverse direction. 9=5V #14=5V, then V=0V, hence motor stop. 9=0V #14=0V, then V=0V, hence motor stop. Loading Motor Speed Control torque loading motor when used with open, then should used above diagram. desired torque could obtained selecting appropriate resistor shown left diagram. necessary, zener diode used right diagram. maximum torque obtained when applied voltage about 6.8V VCC=8V).

Driver
voltage, VREF, reference voltage given bias voltage #23. input signal through amplified 10K/10K times then level shift. level shift produces current difference between input signal arbitrary reference signal. current produced into driver buffer. Driver Buffer operates power Transistor output stage according state input signal. output stage Driver motor rotating forward direction operating transostor other hand, transistor operating, motor rotating reverse direction. When input voltage through below VREF, then direction motor forward direction. When input voltage through above VREF, then direction motor reverse direction. desired change gain, then used. When bias voltage below 1.4V, then output circuit muted. Hence normal operation, bias voltage should used 1.6V~6.5V.
