In this circuit, the National's MM74C908/MM74C918 dual CMOS driver is connected as the oscillator with Schmitt trigger type; R1, R2 are used to generate hysteresis, and R3, C are the inverted timing components, R4 is the down load of the first driver. The current-driving capability is greater than 250mA, so it can be used to the LED matrix or light bulbs.
