sentence: Logic gates are digital components.
sentences_before: A 'logic gate' is an electronic component that can be used to conduct electricity based on a rule. These sources may be two wires or the output of other logic gates.
sentences_after: They normally work at only two levels of voltage, a positive level and a zero level. In the On state, voltage is present. In the Off state, the voltage is at zero. The On state usually uses a voltage in the range of 3.5 to 5 volts. This range can be lower for some uses.
