Meeting of the student “Radio and computer technics” group

On 23.02. 2016 in the room 320 a regular meeting of the student group “Radio and computer technics” was held. On the meeting a reviewed the 555 timer IC.

The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package.

Introduced in 1971 by American company Signetics, the 555 is still in widespread use due to its low price, ease of use, and stability. It is now made by many companies in the original bipolar and also in low-power CMOS types.
