Many novice electronics engineers are afraid to use microcircuits or integrated circuits (IC) when repeating electronic device circuits, arguing that they lack experience in electronics. However, based on the basic principles discussed in this video, you can safely use microcircuits without fear of damaging them or connecting them incorrectly. Devices based on integrated circuits are much more interesting and functional, and the time it takes to make them is reduced, which is very important at the beginning of learning electronics. Here you should think as follows: a microcircuit is a miniature circuit that can be assembled on discrete components. In most cases, an IC can be considered a black box to some of the terminals of which the input signal is supplied, and from others the output signal is removed. A power supply terminal is also required. Often, even experienced developers are not very interested in how a microcircuit is arranged and functions, the main thing is to know what signal is generated at the output of the microcircuit with certain parameters of the input signal. In this video, as an example and training, we will assemble electronic devices for beginners based on the following microcircuits: LM386 - audio amplifier (audio frequency amplifier); LM7805 and 78L05 - integrated voltage stabilizers; NE555 - timer; LM393 - comparator; SN74HC08 - digital logical AND microcircuit. The main parameters that should be paid attention to first of all in order to avoid damage to the IC are considered. 1. What are CMOS microcircuits: • What are CMOS microcircuits. CMOS. On ... 2.
