Tone/frequency 567 decoder IC (integrated circuit) is not only produce an accurate oscillation, but also delivering a good current handling capability. Up to 100 mA will be safely driven by this single chip oscillator, this means that you don’t need any buffering for most small application. With 100mA, you can drive a small bulb, relay, buzzer, or many other devices. […]

Unique applications of 567 tone/frequency decoder IC? Here is one of them: pulse generator with 25% duty cycle (active factor). This signal generator produce square wave pulse, and you use it as clock source or other purpose. Here is the schematic diagram of the circuit. The frequency of this pulse generator is formulated as f=1/(1.1xR1xC1). [Circuit’s schematic diagram source: Philips […]

Precision oscillator can be built using quartz crystal, but with proper component selection, you can also build one with RC (resistor and capacitor) circuit. Not only to build a tone/frequency decoder, 567 IC can be used to build such oscillator as well. The good news is that you need only few components, and a VCO terminal to fine tune the […]

Sometimes, a precise two different frequencies are needed in synchronized circuit design, one with certain frequency and another with exactly double frequency. Usually we build two clock signals with frequency with 1:2 frequencies by feeding an oscillator into a binary counter or T (toggle) flip-flop, so it would be need more components. Using 567 IC, we can build this function […]
