/ f 1102 The invention relates to a pulse technique and is intended for use in automation and logic logic circuits. According to the main authm, NS 813787, a multifunctional logic module is known that contains a three-input element OR whose inputs are connected to the first, second and third input buses, a two-input element OR, the output of which is connected to the output bus, as well as a two-input element And and a three-input element And, the inputs of the three-input element And are connected to the inputs of the three-input element OR, and the output is connected to one of the inputs of the two BODUS OR element, the other input of which is connected to the output of the two-input element And, one of the inputs of which Connected to the output of the three-input element OR, and the other input is connected to the fourth input bus G1X. A significant disadvantage of this module is its low functionality, such as the inability to implement basic logic functions at the same time (OR and OR — NOT, AND AND OR — N, etc. .) In addition, the module has low circuit properties, because it has one output, which reduces its functionality. Oel invention - the expansion of functional capabilities. The goal is achieved so that a multifunctional logic module containing a three-input element OR. The inputs of which are connected to the first, second and third input buses, an input input element OR, the output of which is connected to an A and a two-input input And, and a input input element AND is connected to the inputs of the three-input OR element, and the output is connected to one of the inputs of the two input element OR, the other input of which is connected to the output of the two-input element I, one of the inputs o connected to the output of the three-input element OR, and the other input is connected to the fourth input bus, the element NOT and the second two-input element OR are added, the input of the element is NOT connected to the output of the three-input element OR, the output is connected to the first additional output bus and to the first input of the second two-input element OR, the second input of which is connected to the output of the three-input element AND, and the output to the second additional output bus. 3 The drawing is a diagram of the proposed device. The device contains a traction input element OR 1, the first, second and third Iin-out tires 2,3 and 4, respectively, two-ton input element OR 5, output bus three-input element And 7, two-input element And 8, fourth input bus 9, element NO 1O, second two-input element OR 11, the second additional output bus 12, the first additional output bus 13. The device operates as follows l. Logical variables and set-ups: the switches are fed to the first, second and third 2–5 input buses, from them they are fed to the inputs of the three-input element OR 1 and the three-input element AND 7. After the implementation of the logical function, the output signal from the three-input element OR 1 goes to the input of the two-input element AND 8, to the other input of which the input signal (logical variable or tuning signal) is received from the fourth input bus 9, and to the input of the element NOT 10. After the implementation of the logical function, the output signal from the three-input element And 7 enters t to the input of the two-input element OR 5, i to the other input of which the output signal arrives after the implementation of the logic function by the IZ element, and to the input of the second two-input element OR 11, the fug input of which receives the output signal after the implementation of the logic function by the HE 10. After implementation of the logical function of the elements OR 5, NOT Yu and OR 11 signals taken from their outputs, respectively, are iodine to the output bus 6 of the module, to the first additional output bus 13 of the module and the second additional output bus 12 of the module. The functionality of module 1 is shown in the table. A multifunctional logic module implements all types of logical functions in the basis of AND, OR, and NOT for two and three logical gloves, allows realizing a number of functions of two and three variables; (for example, equivalence) required for automation and computing schemes, simultaneously implement several different and identical basic logical functions of two and three variables. The module has three outputs, which increases its circuit properties. All this significantly expands its functionality and increases reliability.
