Didactic electrical apparatus for teaching digital logic, which is essentially characterized by being constituted by a desk of variable material, shape and dimensions, intended to contain the corresponding functional elements and provided with a panel in which the devices are maneuverable by the user, which are a switch to put into action; a witness lamp indicating said action; some sockets with holes to insert the integrated circuits; printed circuits to fix those sockets to the panel; some strips with screws for the connection of certain components of those integrated circuits, such as capacitors, resistors and others; others regulated with screws with connection of some resistors applied to the positive of the power supply, equipped with outputs in number of four normally, two of the positive and two of the negative, whose power supply provides a low voltage and intensity and is protected properly by a fuse; some output lamps for the visualization of logical states and to follow the evolution of the experienced system; an outlet strip with screw fastening points, each of which is the input of an amplifier-exciter of the corresponding display lamp associated with it; some switches that provide the perceptible input variables by means of the logical switching on or off of said lamps for the simulation of the input variables of the system; a variable pulse generator, with two operating ranges: one slow and one fast selectable through another switch and adjustable by means of a button; an actuator button of a single impulse generator; an input terminal with clamping screws that provides the outputs of the aforementioned switches of the variable pulse generator and the single pulse generator; and some access strips with several points desujeciºn by screw to electrically connect the sockets of the modules with such strips to the integrated circuit.
