ASTABLE OPERATION

If the circuit is connected as shown in Figure 15 (pins 2 and 6 connected) it will trigger itself and free run as a

multivibrator. The external capacitor charges through R_A+ R_Band discharges through R_B. Thus the duty cycle

may be precisely set by the ratio of these two resistors.

Figure 15. Astable

In this mode of operation, the capacitor charges and discharges between 1/3 V_CCand 2/3 V_CC. As in the

triggered mode, the charge and discharge times, and therefore the frequency are independent of the supply

voltage.

Figure 16 shows the waveforms generated in this mode of operation.

V_CC= 5V

Top Trace: Output 5V/Div.

TIME = 20μs/DIV.

R_A= 3.9kΩ

R_B= 3kΩ

Bottom Trace: Capacitor Voltage 1V/Div.

C = 0.01μF
