Figure 8.32. Now we are on the outside of the IC looking in. Pins 8, V plus, and 4, Reset, are tied together and go to plus 12 volts. pin 1 is grounded. There is a .01 u f capacitor connected from pin 5, control input, to ground. There is a resistor from pin 2, trigger input, to plus 12 volts. There is another resistor from plus 12 volts to pin 6, threshold. Pin 6 is tied to pin 7, discharge. A capacitor connects from pins 6 and 7 to ground. Pin 3, output, is not shown connected to anything. End verbal description.
