BOJACK High Quality NE555 Timer IC NE555 is one of the 555 series timing ICs. The pin functions and <br>applications of the 555 series ICs are compatible, but the models are <br>different in price, their stability, power saving, and oscillation frequency.<br> It is not the same; 555 is a very versatile and quite common timing IC<br> that requires only a few resistors and capacitors to generate<br> pulse signals of various frequencies required by digital circuits.<br><br> Main feature:<br><br> 1. Only a simple resistor or capacitor can be used to complete a specific <br>oscillation delay. The delay range is extremely wide and can range<br> from a few microseconds to a few hours.<br> 2, its operating power range is very large, can be matched with TTL, <br>CMOS and other logic circuits, that is, its output level and input trigger<br> level, can match the high and low levels of these series of logic circuits.<br> 3. The output current of the output terminal is large, which can <br>directly push a variety of automatically controlled loads.<br> 4. It has high timing accuracy, good temperature stability and low price.<br><br> Widely used in waveform generation and transformation, <br>measurement and control, household appliances, electronic toys, etc.
