Logic Probe Circuit Diagram - span class news dt sep 14 2019 span nbsp 0183 32 a logic probe is useful tool to measure in checking digital circuits as a meter which is used to measure power in electrical circuits the logic probe will detect a logic 1 and 0 or pulse in a digital circuit it has a handle at the head of a pin for measuring different parts of the circuits or ic pin notes this logic probe is based on a single cmos 4001 ic this ic contains four 2 input nor gates all of the gates are used in this circuit power for the logic probe is taken from the circuit under test and because cmos technology is used the with digital circuits we often only care whether a signal is logic high or low a logic probe allows you to peek in at logic signals inside an operating circuit on an as desired basis no need to wire up leds to monitor signals although that s sometimes exactly what you want and we ll cover that later in this.
guide posted by circuit diagram in digital electronic circuits logic probe is useful tool to measure in a check digital circuits as a meter which is used to measure power in electrical circuits logic probe was used for detection logic 1 and 0 or pulse in a digital circuit logic probe circuit the logic probe circuit we will build to read logic levels is shown below this above circuit built on a breadboard is shown below this logic probe will light up the green led when the logic input is high a 1 and will light up the red led when the logic input is low a 0 this logic probe is based on a single cmos 4001 ic this ic contains four 2 input nor gates all of the gates are used in this circuit power for the logic probe is taken from the circuit under test and because cmos technology is used the circuit will work with voltages from 3
