DATASHEET and Circuit Diagram

The diagram below circuits the piezo transducer which is used to trigger a 555 monostable circuit. Instead of triggering a monostable circuit, a piezo transducer commonly be used to trigger a thyristors.

When it is deformed, a piezo transducer will generate a voltage. If the piezo is tapped it will generate a small voltage, which is enough for triggering a circuit instead of the uncased piezo (which makes a good transducer).

The 556 timer is a dual version of the 555 single timer, they suitable for monostable or astable operation. It results in providing effective solutions for timing and pulse circuit applications.

The picture shows you with Tone Burst Generator Circuit Diagram using the 556 dual timer. It is connected as a one shot circuit. The pulse established by one shot turns on the oscillator allowing a burst of pulses to be generated.

A sequential timer circuit device are used in many applications for initializing conditions during start-up or for activation of test signals in sequences such in test equipment device. The circuit diagram below shows a sequencer circuit with possible applications in many sistems.

As you can see, it uses the NE555 precision timer IC which capable of producing accurate time delays or oscillation. These timing circuits can be connected to provide such sequential control with various combinations of astable or monostable circuit connections. You can used it with or without modulation for extremely flexible waveform control.
