CD 4049BE / HCF 4049UBE / HEF 4049BP 6 inverting buffers + TTL driver

Archived from the original on Dual retriggerable precision monostable multivibrator with reset. With termenvox, this usually undesirable effects were put to good use. Combining touchable pads in various manners can bring out interesting — very complex results. Decade counter with decoded 7-segment display outputs and display enable.

The integrated circuit is fully optimized and used entirely to make a two channel system with some open options for additional hacking. For more details, please see the next section “Datasheet List by manufacturer”. If you have a thing for DIY electronics, follow the descriptions below. Some were built later in the vicinity of Cirkulacija 2 collective and the positive results made it perfect to develope further.


HEF Hex Inverting Buffer by Philips Semiconductor

Digital electronics Electronic design Electronics lists Integrated circuits. Octal bus transceiver ; tri-state outputs. Hex inverting buffer replaced by Termenvox is in essence a capacitive sensor that functions by comparing the frequencies of two oscillators. Views Read Edit View history. Octal D-type transparent latch tri-state. It was further developed for special needs of Theremidi Orchestra.

The “datasheet” column countains ONLY one datasheet archive. It produces a two-channel audio output. DIP 24, SO Hex non-inverting buffer replaced by DIP 14, SO Preset Divide By N Counter”. Decade counter with 10 decoded outputs 5-stage Johnson 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. From Wikipedia, the free encyclopedia.

One of the oscillators is fixed and the other is coupled with the antenna to its surroundings. This page was last edited on 2 Decemberat The following is a list of CMOS series digital logic integrated circuits.



BCD 7-segment decoder, hexadecimal, active high [8]. Hex non-inverting buffer with tri-state outputs.

Retrieved from ” https: The closer the hand or any part of the body — the higher the total capacitance and thus the lower the oscillating frequency.

Mikroelektronik in der Amateurpraxis [ Microelectronics for the practical amateur ] in German 3 ed.

List of books about series integrated circuits. Dual retriggerable monostable multivibrator with reset. Quad analog switch low “ON” resistance.

The circuit has simplified oscillator sections due to use of Schmitt het of gates. A human moving their hand acts as a capacitor to ground and adds themself to the oscillating system. By using this site, you agree to the Terms of Use and Privacy Policy.
