NE555 IC that has an 8-pin (leg) is one of the electronic components is quite well known, simple, and versatile with size less than 1\/2 cm3 (cubic centimeter).<\/span> Basically, the main application is used as the IC NE555 timer (Timer) with monostable circuit operation and Pulse Generator (pulse generator) with astable circuit operation.<\/span> In addition, it can also be used as a Time Delay Timing Generator and Sequential.<\/span><\/p>\n

Judging from the manufacturer, IC NE555 is a manufacturer of Philips and Texas Instruments.<\/span> Actually many companies that make IC similar to this NE555.<\/span> Each company issued with the design and the technology is different.<\/span> For example, National Semiconductor makes and call it by the name of LM555, Motorola \/ ON-Semi designing with CMOS transistors so komsusi powernya small enough and named MC1455.<\/span>
\n<\/a><\/p>\n

Maxim makes its CMOS version under the name M7555.<\/span> Although the name is different, but mutually compatible and the diagram functions (functions and the pin position) from each other.<\/span> Although compatible with each other, there are still several different specific characteristics such as power consumption, maximum frequency and so forth.<\/span> All of them, at present more details on each manufacturer’s datasheet.<\/span><\/p>\n

Practically, the function and application of IC NE555 is widely used among others as a regulator of the alarm, as the driving DC motors, can be combined with IC TTL (transistor-transistor logic) and as input a digital clock for the “purposes of the desired” (if only for a digital clock usual , many IC that can be directly used), can also be used in a series of touch switch, and when combined with infrared or ultrasonic, NE555 can be used as a transmitter or remote control.<\/span><\/p>\n

Especially when combined with modulation techniques and some electronic components that support, can be produced remote control multi channel that can control some other electronic device in a remote (indeed reach the distance is not too far away, at about 10m – 20m. The difference with the use of radio frequencies) ,<\/span> For practical purposes in making a circuit with this IC, you need to know is the position and function of each leg only, which can be seen as follows:<\/span>
\n<\/a><\/p>\n

As for knowing how to work and the physical structure of the IC NE555 detail can be seen from the circuit \/ internal components.<\/span>
\n<\/a><\/p>\n

In the block diagram above, the internal IC NE555 tiny consists of: two comparators (comparator voltage), 3 pieces of resistors as the divisor tengangan, 2 pieces of transistors (in practice and analysis work, transistors are connected to the pin 4 is usually directly connected to the Vcc), 1 piece SR flip-flop that will set the output on a particular logic state, and 1 inverter<\/span>
\n<\/a><\/p>\n

By looking at Figure 2 and Table 1, in general the internal workings of this IC can be explained that, when the pin 4 as a reset by a voltage of 0V or logic low (0), then the output on pin 3 bound to logic low as well.<\/span> Only when pin 4 (reset) by signal or logic high (1), then the output of this NE555 will change according to the threshold voltage (pin 6) and a trigger voltage (pin 2) are given.<\/span><\/p>\n

When the threshold voltage on pin 6 exceeds 2\/3 of the supply voltage (Vcc) and logic outputs on 3 pin logic high (1), the internal transistor (Tr) will turn-on so that it will lower the threshold voltage to less than 1\/3 of the supply voltage.<\/span> During this time interval, the output at pin 3 to logic low (0).<\/span> After that, when the input signal or trigger in the pin 2 which logic low (0) begin to change and reach 1\/3 of Vcc, the internal transistor (Tr) will turn-off.<\/span><\/p>\n

Switching transistor turn-off will increase so that the output voltage IC NE555 threshod is originally a logic low (0) will return a logic high (1).<\/span> Actually, the workings of the base IC NE555 is a full combination and not in spite of all the internal components consisting of three resistors, 2 comparators, 2 transistors, 1 flip-flop and 1 inverter, all of which will be discussed on another occasion ,<\/span> Simultaneously with the circuit \/ external components that support them.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
