Once we draw the input and output graph we will have something like this. With multiple gates and fast output the 74HC14 usage is further promoted. For understanding this better let us consider the switching diagram of a gate.

For understanding the use of 74HC14 consider: When you want to eliminate noise in digital electronics. SO those are some basics: Or, hold the two resistor leads in your fingers and squeeze to change your skin resistance. Once datasheett start stringing circuits together, one circuit controlling another circuit… oh, boy. Also Also provide an analog signal at the input.

We want to mix all three oscillators together. We can use each gate like this to get the desired output. Where you want to convert signal waveforms to square wave.

Handmade Electronic Music Routledge, ; chapter As shown in circuit, we 401106b giving a sinusoidal wave at the input and taking Vout as output of gate. You can also change the capacitor value… swap in some different ones and see what happens.


Ratasheet you can get 6 oscillators out of one chip. Replace the resistor with a photocell. Or wire in a pot variable resistor to control the pitch. After experimenting and finalizing your design, you can transfer it to one of our Oscillator boards to make it more gig-worthy.

Oscillators can also control other oscillators, making more complex tones. The gates in 74HC14 take some time to provide output to the given input. Inverter Schmitt triggers in this chip can provide output which is negated logic input. Oscillators produce Dxtasheet signals, which we can amplify and hear as tones. Once it reaches that point, the output voltage again goes HIGH. These delays must be considered at higher frequencies otherwise we will have major errors.

Also there will be 40106bb triggering and noise beyond operating frequencies. You can get some pretty complex sounds with just a few basic building blocks, repeated a few times. TL — Programmable Reference Voltage. This time delays are called switching times.

BTW, most chips do different things and have different pin-outs. We can do the same thing here.

Check each oscillator out one at a time, by listening to each output separately. Try using variable resistors and start monkeying with the rate of the first oscillator, then the frequency of the second… then both. All 3 oscillators signals are now mixed together, out to the amp. Schmitt trigger gates in 74HC14 can covert non-square wave forms to square waves. This tutorial shows how to build oscillators on a solderless breadboard.


This chip gates can be used to get inverted logics for controllers or digital electronics. The simplified internal structure can be given as below.

Now for understanding the usage of gate let us pick a single gate and connect the power to chip. Total is ns for each cycle.

A sweet setup would be 3 pairs of FM oscillators with all three outputs mixed datashee speed controls on the slow oscillators, photocells on the fast ones, individual volume controls… you get the idea. You should be able to hear the first oscillator switching the tone of the dataseet oscillator back and forth between low to high.

In another sense it is the output voltage. Get all 3 oscillators happy before continuing. So we have datasheft, and we can change their frequency by changing the values of either the resistor or capacitors. On chips like this with multiple elements, all the inverters on the chip are the same, so you can pick whichever one makes the layout easiest. Once it reaches threshold voltage, the output voltage goes LOW.

When you want logic inverter. This cycle goes on. Ov course, you might have something different by now….

With Schmitt trigger gate we can convert sinusoidal or triangular wave to square wave.
