Dual retriggerable precision monostable multivibrator with reset.

Hex non-inverting buffer with tri-state outputs. Retrieved from ” https: Digital electronics Electronic design Electronics lists Integrated circuits. List of books about series integrated circuits. The circuit has simplified oscillator sections due to use of Schmitt triggering of gates.

It was further developed for special needs of Theremidi Orchestra. Preset Divide By N Counter”. From Wikipedia, the free encyclopedia. It produces a two-channel audio output.

With termenvox, this usually undesirable effects were put to good hhef. Termenvox is in essence a capacitive sensor that functions by comparing the frequencies of two oscillators.


In fact, it is a cast-away of the development in the field of radio — namely: The invention of theremin goes hand in hand with the pioneering years of radio — electronic amplification — the s. By continuing to use this website, you agree to their use.

The “datasheet” column countains ONLY one datasheet archive. Octal bus transceiver ; tri-state outputs. One of the oscillators is fixed and the other is coupled with the antenna to its surroundings.

Quad analog switch low “ON” resistance. DIP 14, SO If you have a thing for DIY electronics, follow the descriptions below.

Decade counter with 10 decoded outputs 5-stage Johnson counter. To find out more, including how to control cookies, see here: Hex non-inverting buffer replaced by Archived from the original on Phase-locked loop with VCO.

HEF Hex Inverting Buffer by Philips Semiconductor

DIP 24, SO Combining touchable pads in various manners can bring out interesting — very complex results. Some were built later in the vicinity of Cirkulacija 2 collective and the positive results made it perfect to develope further. Octal D-type flip-flop ; positive-edge trigger tri-state. Views Read Edit View history. Decade counter with decoded 7-segment display outputs and display enable. Two pairs are used as variable frequency oscillators, lower and high frequencies, and third pair is used 404 mixed amplifying, filtering, oscillating feedback mode to play around with the existing pads all over the system.


Dual retriggerable monostable multivibrator with reset. The closer the hand or any part of the body — the higher the total capacitance and thus the lower the oscillating frequency.
