The 555 timer is a highly versatile and useful integrated circuit that many people don\'t often take the time to understand and appreciate for its many uses. The 555 timer is useful for digital and analog applications, and it has the capability to create many different signals like square, triangular and pulse waves. It can also be used for measuring frequency, time delay, and voltage. This versatile timer can provide almost any desired signal along with precise timing and an easy to use package.

The 555 timer is typically found in three varieties; the 558 timer, the 555 timer, and the 556 timer. Each of these differs in its capabilities and input/output (I/O) pins. To determine the employment of each type of timer, the applications of the 558, 555 and 556 must be understood.

558 Timer Applications

The 558 timer is a dual timer that can be used to form a wide variety of applications. It is capable of producing a high-frequency pulse train, pulse width modulation (PWM), and pulse position modulation (PPM) signals. It can also be used for applications such as alarms, LED lighting systems, fluorescent light dimmer circuits, and vehicle burglar alarms. Additionally, it can be used in temperature sensing circuits, frequency to voltage converters, motor speed control, and audio oscillators.

555 Timer Applications

The 555 timer is most commonly used for applications such as tone generators, time delay circuits, pulse width modulation (PWM) generation, and hardware interfaces. It can be used to create a variety of waveforms depending on the input signal. It can be used for basic audio signal generation, such as beeps, tones, and pulses. Additionally, the 555 timer can be used in frequency-controlled timing applications, which allow for precise timing intervals without the need for manual adjustment.

556 Timer Applications

The 556 timer is a dual timer with a single output. It is typically used for applications requiring precise timing, such as timing circuits, oscillators, motor speed control and pulse generation. It can also be used to generate pulse width modulation (PWM) signals. Additionally, it can be used to control motors and LEDs and act as an adjustable timer, providing precise timing intervals.

Working Principles

The 558, 555 and 556 timers all have similar working principles. They all contain two logic gates, one flip flop, and two voltage comparators. Depending on the input signal, the logic gates and voltage comparators will create a high voltage output. This high voltage output is known as a trigger, which is used to activate the flip flop, thereby allowing the chip to be used in a variety of timing intervals. The exact timing interval that is produced depends on the values of a few external components, such as resistors and capacitors.

The 558, 555 and 556 timers can all be used for a variety of applications, depending on the exact implementation of the timer. With their versatile I/O capabilities, they can be used to act as a timer, an oscillator, a PWM controller, and many other devices. The working principles behind each respective timer are similar, but the exact applications each timer is best suited for vary.
