The invention provides a 4 times 2 grid multi-scroll chaotic attraction subsystem and circuit, which consists of a first channel circuit, a second channel circuit, a third channel circuit and three paths of symbol function circuits. The first channel circuit consists of an invert adder U1, an integrator U2, an inverter U3 and resistors R11, R12, R13, R14 and Rx1 and Rx2. The second channel circuit consists of an invert adder U4, an integrator U5, an inverter U6 and resistors R21, R22, R23, R24 and Ry1 and Ry2. The third channel circuit consists of an invert adder U7, an integrator U8, an inverter U9 and resistors R31, R32, R33, R34 and Rz1, Rz2, Rz3, and Rz4. The invention provides one 4 times 2 grid multi-scroll chaotic attraction subsystem, which is subject to experimental proof with a simulation circuit, and has wide application prospect and important application value in the fields such as secret communication.
