Product description
1) The full-chip 8-channel digital answerer is a new product specially developed for the spot check of electronic assembly and debugging skills. The circuit design adopts the time-base circuit and decoding drive widely used in digital circuits. The circuit components all adopt the most popular SMD. The package series is a SMT soldering training kit worth learning and circuit analysis .
2) simple principle
The circuit includes answering, coding, priority, latch, digital display and reset circuits. Eight-way priority answering can be performed at the same time. After the button is pressed, the buzzer will sound and the number of the priority answerer will be displayed (light-emitting diode ). After the answer is successful, press the button again, the display will not change unless the reset button is pressed. After reset, the display is cleared and you can continue to answer. S1-S8 are the answer keys, and S9 is the reset key. CD4511 is a latch having BCD-7 segment / decoder / driver circuit in one integrated circuit, wherein the BCD code input 1,2,6,7, 9 - 15 feet display output, pin 3 (LT) To test the output terminal, when "LT" is 0, the output is all 1, pin 4 (BI) is the blanking end, when BI is 0, the output is all 0, pin 5 (LE) is the latching enable end, when LE When changing from "0" to "1", the output terminal keeps the display state when LE is 0. Pin 16 is the positive power supply, and pin 8 is the negative power supply. 555 and the peripheral circuit form the responder signal ring circuit. Digital display is composed of light-emitting diodes
