Dual retriggerable precision monostable multivibrator with reset. DIP 24, SO BCD 7-segment decoder, hexadecimal, active high [8]. The following is a list of CMOS series digital logic integrated circuits. Octal bus transceiver ; tri-state outputs.

The closer the hand or any part of the body — the higher the total capacitance and thus the lower the oscillating frequency. List of books about series integrated circuits.

From Wikipedia, the free encyclopedia.

Termenvox is in essence a capacitive sensor that functions by comparing the frequencies of two oscillators. Octal D-type flip-flop ; positive-edge trigger tri-state.


It produces a two-channel audio output. This site uses cookies. The free-running frequency no hand near the antenna of this variable oscillator should ideally be 409 same as that of the fixed frequency oscillator — making the difference of these two frequencies equal to zero. Decade counter with decoded 7-segment display outputs and display enable.


Phase-locked loop with VCO. Quad analog switch low “ON” resistance.

List of 4000-series integrated circuits

Hex non-inverting buffer with tri-state outputs. Hex non-inverting buffer replaced by Digital electronics Electronic design Electronics lists Integrated circuits. A human moving their hand acts as a capacitor to ground and adds themself to the oscillating system. Views Read Edit View history.

To find out more, including how to control cookies, see here: Octal D-type transparent latch tri-state. The “datasheet” column countains ONLY one datasheet archive. The integrated circuit is fully optimized and used entirely to make a two channel system with some open options for additional hacking. Hed page was last edited on 2 Decemberat Mikroelektronik in der Amateurpraxis [ Microelectronics for the practical amateur ] in German 3 ed.

The invention of theremin goes hand in hand with the pioneering years of radio — electronic amplification — the s. One of the oscillators is fixed and the other is coupled with the antenna to its surroundings.

DIP 16, SO Retrieved from ” https: By using this site, you agree to the Terms of Use and Privacy Policy. Combining touchable pads in various manners can bring out interesting — very complex results. Preset Divide By N Counter”. Two pairs are used as variable frequency oscillators, lower and high frequencies, and third pair is used in mixed amplifying, filtering, oscillating feedback mode to play around with the existing pads all over the system.


Archived from the original on By her to use this website, you agree to their use. Dual retriggerable monostable multivibrator with reset. Hex inverting buffer replaced by Decade counter with 10 decoded outputs 5-stage Johnson counter. DIP 14, SO Some were built later in the vicinity of Cirkulacija 2 collective and the positive results made it perfect to develope further.

In he, it is a cast-away of the development in the field jef radio — namely: The circuit has simplified oscillator sections due to use of Schmitt triggering of gates. With termenvox, this usually undesirable effects were put to good use. It was further developed for special needs of Theremidi Orchestra.
