Subtraction Cycle Counter Circuit Kit 74LS192 Parts with Simulation Electronic DIY Training Kit

Feature Electronic kit for French cycle counter circuit This circuit is a digital circuit composed of a signal generator a NAND gate a bidirectional counter and a decoder Through this circuit you can understand the functions and usage of the NAND gate counter and decoder The kit is made of international standard plates the pads are all tinned high strength fireproof and anti fall materials and can be disassembled repeatedly The PCB board design is reasonable and the commonly used chip components are used Send information and simulation Board size 75 46mm board thickness 1 6mm circuit working voltage 5VCircuit description In the circuit IC2A IC2B and C2 R8 Rw1 form an oscillating circuit which outputs a square wave signal The frequency of the square wave can be adjusted by Rw1 When the power is just turned on pin 1 and pin 2 of IC2A are high level and pin 3 is output Low level both sides of C2 without charge are low level pin 5 and pin 6 of IC2B are also low level pin 4 outputs high level this high level voltage charges C2 through resistors Rw1 and R8 and the voltage on the right side of C2 gradually Rise after a period of time the voltage on the right side of C2 reaches the high level condition pins 5 and 6 of IC2B become high level pin 4 becomes low level output and pins 1 and 2 connected between IC2A and pin 4 become low Flat pin 3 outputs a high level the voltage on the left side of C2 rises to a high level condition the charge stor
