The 555 IC timer is an integral part of electronics projects. Whether it is a simple project that involves a single 8-bit microcontroller and some peripherals or a complex system involving chips (SoCs), 555 work timer is involved. These provide time delays, such as an oscillator and as a flip-flop element among other applications.
Introduced in 1971 by US firm Signetics, the 555 is still widely used due to its low price, ease of use and stability. It is manufactured by many companies in the bipolar types and low consumption CMOS original. According to one estimate, one million units were manufactured in 2003 alone. (That time, only 555 knew it was a cough syrup).
Depending on the manufacturer, the standard 555 package includes 25 transistors, 2 diodes and 15 resistors on a silicon chip installed in an 8-pin dual-in-line mini package (DIP-8). The variants consist of combining multiple tiles on a board. However 555 is still the most popular. Let's look at the pin diagram to get an idea about the IC timer before talking about 555 work timer.
