Effective date : There is provided a moisture-responsive system for protecting the interior of an enclosure such as a motor vehicle which includes an opening; a closure for the opening; a moisture sensor for providing a moisture signal in response to sensing of moisture in excess of a predetermined threshold; a circuit coupled to the closure and the moisture sensor for providing a signal to actuate the closure in response to receipt of a moisture signal and for sensing obstructions of the closure and temporarily terminating the actuation of the closure in response thereto. There is also provided an improved moisture sensor comprising conductive plates separated by and supported on an insulating layer with a raised bulbous portion which extends above the plates to predetermine the amount of moisture necessary to electronically bridge the gap between the conductive plates and therefore the level at which the sensor commences to sense moisture.

UA741CN Operational Amplifier

The Web This site. Each logic family is designed so that gates and other logic ICs within that family and other related families can be easily combined, and built into larger logic circuits to carry out complex functions with the minimum of additional components.

If something is not 1 it must be 0, if it is not on, it must be off. A logic gate is a small transistor circuit, basically a type of amplifier, which is implemented in different forms within an integrated circuit. Each type of gate has one or more most often two inputs and one output. The principle of operation is that the circuit operates on just two voltage levels, called logic 0 and logic 1. These values are represented by two different voltage levels. In 5 volt logic, 1 is ideally represented by 5V and 0 by 0V, and in 3.

When either of these voltage levels is applied to the inputs, the output of the gate responds by assuming a 1 or a 0 level, depending on the particular logic of the gate.

The logic rules for each type of gate can be described in different ways; by a written description of the action, by a truth table, or by a Boolean algebra statement. The actions of any of these gates can also be described using Boolean statements. These use letters from the beginning of the alphabet, such as A, B, C etc. The letters have no meaning in themselves, other than just to label the various points in the circuit. The letters are then linked by a Boolean symbol indicating the logical action of the gate.

Alternatively the action of any of the 7 types of logic gate can be described using a written description of its logic function. Another useful way to describe the action of a digital gate or a whole digital cicuit is to use a truth table. Each table consists of two or more columns, one column for each input or output; the number of lines in the column will be enough to record all possible logic states for that input or output.

The top table is for a simple two input and gate. This has two inputs labelled A and B and one column X for the output. Comparing the truth table with the written description in "Describing the Action of Logic Gates" above it can be seen that the truth table follows the written description by showing that output X is at logic 1 only when inputs A and B are at logic 1, otherwise where the three upper lines are 00, 01 and 10 the output is logic 0. The second table in Fig.

Notice that now the truth table is expanded to illustrate the logic levels at four further inputs or outputs in addition to inputs A and B before the final output X is illustrated in the right hand column. Such complex tables can be of great value in both digital circuit design or fault finding.

In Fig 2. The gate animations allow you to choose any one of the 7 basic gates and see a new page with an animated image of the gate in operation. Use the animation to become familiar with the operation of each of the gates. To return to this page, just close the page showing the animation. To easily understand more complex digital circuits it is important to develop a good mental picture of the expected output from each gate for any possible input.

The animations available in Fig. Each animated diagram shows the input and output conditions for one of the seven logic functions in its two input form. Some types of gate however, are also available with more e. For these gates the truth tables would need to be extended to include all possible input conditions. Because gates are manufactured in IC form, typically containing two to six gates of the same type, it is often uneconomical to use a complete IC of six gates to perform a particular logic function.

A better solution may be to use just a single type of gate to perform any of the logic operations required. Although it may not seem efficient to use several universal gates to perform the function of a single gate, if there are a number of unused gates in one or more NAND and NOR ICs, these can be used to perform other functions such as AND or OR rather than using extra ICs to perform that function.

This technique is especially useful in the design of complex ICs where whole circuits within the IC can be fabricated using a single type of gate. Alternatively the NOT function can be achieved by using only 1 input and connecting the other input permanently to logic 1.

The reason for such conversions is usually cost. This may not seem very useful since none of the basic 74 series ICs are expensive, but when several thousand units of a particular circuit are to be manufactured, the small savings in cost and space on printed circuit boards by maximising the use of otherwise unused gates in multi gate ICs can become very important. Typically, standard logic gates are available in 14 pin or 16 pin DIL dual in line chips.

The number of gates per IC varies depending on the number of inputs per gate. The greatest number of inputs on a single gate is on the 13 input NAND gate, which is accommodated in a 16 pin package. Hons All rights reserved.

Documentation Help Center Documentation. Model common integrated circuits using amplifiers, oscillators, timers, and counters. Produce a single logic output by combining Boolean functions. With the two switches in their default positions, both inputs to the flip-flop are set high so its output state toggles each time the clock signal goes low. Initial conditions are passed to the relevant NAND gates via the initialization commands of the block mask.

The IC is basically designed for low voltage commercial applications, apart from commercial applications it is also a famous IC among electronic hobbyists and experimenters. The internal gain of the IC is set to 20 but it can be adjusted by connecting a resistor and a capacitor in series between the pin number 1 and 8, by this procedure the user can adjust the gain between 20 to

Digital Integrated Circuits in Proteus

In digital logic, an inverter or NOT gate is a logic gate which implements logical negation. The truth table is shown on the right. An inverter circuit outputs a voltage representing the opposite logic-level to its input. Its main function is to invert the input signal applied. If the applied input is low then the output becomes high and vice versa. Since this 'resistive-drain' approach uses only a single type of transistor, it can be fabricated at a low cost.
