IC 7408

Basic gates are already packed in an IC (Integrated Circuit), for gate use type IC 7408. Since in this case will use the input / input 3 pieces then by combining the two gates can be obtained 3 input meant (by connecting the output 3 feet to 4 feet or five inputs as shown in the image below. gate basic price only had 2 are 0 and 1. valuable 0 if the voltage is worth 0 to 0.8 volts and a valuable one if the voltage is worth 2-5 Volts. Operating gates : If all input is connected to the ground or everything apart then the output will be worth 0, so that the indicator lights are not on. Similarly, if only one apart and other inputs given input voltage of Vcc, the light still will not turn on. the lights will be lit if all inputs rated voltage of Vcc
