Yef4081 first is to use a NAND gate and invert the output. When both buttons are not pressed. TL — Programmable Reference Voltage. For realizing the above truth table let us take a simple AND gate application circuit as shown below. If a is not available, there are several ways to achieve an AND gate.
The chip is basically used where AND logic operation is needed. Both transistors will be ON and voltage across both of them will be zero. A few mentioned below.
Practical Electronics/IC/4081
The chip is used in systems where high speed AND operation is needed. Submitted by admin on 6 April Because of this the chip can be used for high speed AND operations. The circuit working can be explained in few stages below: Retrieved from ” https: With that the drop across resistor R1 will be zero. The two inputs of AND gate are driven out from bases of the two transistors.
Datadheet second will require only one IC, but only two dwtasheet can be made. In this state the current flow through base of both transistors will be zero.
For more information about the AND gate in general, see this module.
When any one of the buttons is pressed. In the circuit two transistors are connected in series to form a AND gate. This page was last edited on 16 Decemberat Because total VCC appears across transistors the drop across resistor R1 will be zero. When both buttons are pressed. The chip is available in different packages and is chosen depending on requirement.
A selection of different manufacturers’ datasheets is given below:. It is really popular and is available everywhere.
The arrangement of the CMOS components is shown below:.

These are available from manufacturers. The truth table for one of the four gates is shown to the right. From Wikibooks, open books for an open world. Policies and guidelines Contact us. The pinout diagram, given on the right, is the standard two-input logic gate IC layout:.
The chip provides TTL outputs which are needed in some systems. These two inputs are connected to buttons to change the logic of inputs. Views Read Edit View history. The first method with require two ICs to implement, but a total of four gates can be made.
Output of the AND gate is the voltage across resistor R1. For better understanding the internal working let us consider the simplified internal circuit of AND gate as shown below. The four AND gates in the chip mentioned earlier are connected internally as shown in diagram below.
The description for each pin is given below.
By using this site, you agree to the Terms of Use and Privacy Policy. This LED is connected to detect the ehf4081 of output. At this time the total Hdf4081 appears across resistor R1. In other languages Add links. Because output is nothing but voltage across resistor R1 it will be LOW. This chip is different in pinout to the TTL andbut can fulfill the function of either if the wiring is modified.
After verifying the three states, you can tell that we have ddatasheet the above truth table. This is discussed on this page. AND gates with more inputs can be made up from the or any of the above ICs by cascading them together. There are four AND gates in the chip, we can use one or all gates simultaneously.
