Para la comunidad, la electrionica es vital en todo lugar, y mas aquí. Anexo los primeros pasos... informacion gratis.. http://talkingelectronics.com/projec...0_IC-Ccts.html ![]() For our other three free eBooks, Go to: 1 - 100 Transistor Circuits Go to: 101 - 200 Transistor Circuits Go to: 50 - 555 Circuits 12 IC CIRCUITS as of 19-2-2010 ![]() See TALKING ELECTRONICS WEBSITE email Colin Mitchell: talking@tpg.com.au INTRODUCTION This is the third part of our Circuits e-book series. It contains a further 100 circuits. This time we have concentrated on circuits containing one or more IC's. It's amazing what you can do with transistors but when Integrated Circuits came along, the whole field of electronics exploded. IC's can handle both analogue as well as digital signals but before their arrival, nearly all circuits were analogue or very simple "digital" switching circuits. Let's explain what we mean. The word analogue is a waveform or signal that is changing (increasing and decreasing) at a constant or non constant rate. Examples are voice, music, tones, sounds and frequencies. Equipment such as radios, TV's and amplifiers process analogue signals. Then digital came along. Digital is similar to a switch turning something on and off. The advantage of digital is two-fold. Firstly it is a very reliable and accurate way to send a signal. The signal is either HIGH or LOW (ON or OFF). It cannot be half-on or one quarter-off. And secondly, a circuit that is ON, consumes the least amount of energy in the controlling device. In other words, a transistor that is fully turned ON and driving a motor, dissipates the least amount of heat. If it is slightly turned ON or nearly fully turned ON, it gets very hot. And obviously a transistor that is not turned on at all will consume no energy. A transistor that turns ON fully and OFF fully is called a SWITCH. When two transistors are cross-coupled in the form of a flip flop, any pulses entering the circuit cause it to flip and flop and the output goes HIGH on every second pulse. This means the circuit halves the input pulses and is the basis of counting or dividing. It is also the basis of a "Memory Cell" as will will hold a piece of | |
