The circuit working can be explained in few stages below: The first is to use a NAND gate and invert the output. These two inputs are connected to buttons to change the logic of inputs. The first method with require two ICs to implement, but a total of four gates can be made. Both dahasheet will be ON and voltage across both of them will be zero. The truth table for one of the four gates is shown to the right.

For realizing the above truth table let us take a simple AND gate application circuit as shown below. These are available from manufacturers.

Practical Electronics/IC/4081

In the circuit two transistors are connected in series to form a AND gate. The pinout diagram, given on the right, is the standard two-input logic gate IC layout:. At this time the total VCC appears across resistor R1. This hef44081 discussed on this page.

Retrieved from ” https: When any one of the buttons is pressed. Because output is nothing but voltage across resistor R1 it will be LOW. The description for each pin is given below.

After verifying the three states, you can tell that we have satisfied the above truth table. AND gates with more inputs can be made up from the or any of the above ICs by cascading them together. Because of this the chip can be used for high speed AND operations.

The chip is available in different packages and is chosen depending on requirement. Output of the AND gate is the voltage across resistor R1. The arrangement of the CMOS components is shown below:. A selection of different manufacturers’ datasheets is given below:. Because total VCC appears across transistors the drop across eatasheet R1 will be zero.

In other languages Add links. The two inputs of AND gate are driven out from bases of the two transistors.

This chip is different in pinout to the TTL dattasheetbut can fulfill the function of either if the wiring is modified. Submitted by admin on 6 April The chip provides TTL outputs which are needed in some systems. With that the drop across resistor R1 will be zero.

Views Read Edit View history. For more information about the AND gate in general, see this module. The chip is used in systems where high speed AND operation is needed. It is really popular and is available everywhere. If a is not available, there are several ways to achieve an AND gate. A few mentioned below.

When both buttons are pressed. From Yef4081, open books for an open world.
