Logic pen is also called as logic test probe, which is a commonly-used tool in testing the logic states of the dots in a digital circuit. The logic states in a digital circuit can be divided as high level ‘1’, low level ‘o’ and high impedance state (infloating). The test results of the logic states can be displayed by a luminous diode, or an acoustical generator, or a digital luminous diode. The above picture is a logic test pen composed of hex-inverter CD4069 and luminous diode.
