Digital electronics Electronic design Electronics lists Integrated circuits.

For more details, please see the next section “Datasheet List by manufacturer”. Hex inverting buffer replaced by DIP 14, SO The following is a list of CMOS series digital logic integrated circuits.

Phase-locked loop with VCO. It was further developed for special needs of Theremidi Orchestra. Views Read Edit View history.


It produces a two-channel audio output. The free-running frequency no hand near the antenna of this variable oscillator should ideally be the same as that of the fixed frequency oscillator — making the difference of these two frequencies equal to zero.

Hex non-inverting buffer replaced by Mikroelektronik in der Amateurpraxis [ Microelectronics for the practical amateur ] in German 3 ed.


The closer the hand or any part of the body — the higher the total capacitance and thus the lower the oscillating frequency.

Combining touchable pads in various manners can bring out interesting — he complex results. Retrieved from ” https: This site uses cookies. Octal D-type transparent latch tri-state. By using this site, you agree to the Terms of Use and Privacy Policy. This page was last edited on 2 Decemberat The circuit has simplified oscillator sections due to use of Schmitt triggering of gates.

The integrated circuit is fully optimized and used entirely to make a two channel system with some open options for additional hacking. If you have a thing for DIY electronics, follow the descriptions below. A human moving their hand acts as a capacitor to ground and adds themself to the oscillating system. Decade counter with 10 decoded outputs 5-stage Johnson counter.

Semiconductor: HEF4049BP (HEF 4049BP) – HEX INVERTER BUFFER…

Dual retriggerable precision monostable multivibrator with reset. Octal D-type flip-flop ; positive-edge trigger tri-state. BCD 7-segment decoder, hexadecimal, active high [8]. To find out more, including how to control cookies, see here: List of books about series integrated circuits. DIP 24, SO Preset Divide By N Counter”. Archived from the original on With termenvox, this usually undesirable effects were put to good use. The invention of theremin goes hand in hand with the pioneering years of radio — electronic amplification — the s.


Octal bus transceiver ; tri-state outputs. Termenvox is in essence a capacitive sensor that functions by comparing the frequencies of two oscillators.

Decade counter with decoded 7-segment display outputs and display enable. Quad analog switch low “ON” resistance. Dual retriggerable monostable multivibrator with reset. Hex non-inverting buffer with tri-state outputs. Some were built later in the vicinity of Cirkulacija 2 collective and the positive results made it perfect to develope further. The “datasheet” column countains ONLY one datasheet archive.

From Wikipedia, the free encyclopedia. In fact, it is a cast-away of the development in the field of radio — namely: DIP 16, SO One of the oscillators is fixed and the other is coupled with the antenna to its surroundings. 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.
