When both buttons are not pressed. This page was last edited on 16 Decemberat Both transistors will be ON satasheet voltage across both of them will be zero.

HEFBP Datasheet pdf – Quad 2-input AND gate – NXP Semiconductors

The description for each pin is given below. The chip is used in systems where high speed AND operation is needed.

In this state the current flow through base of both transistors will be zero. When both buttons are pressed. These two inputs are connected to buttons to change the logic of inputs. For better understanding the internal working let us consider the simplified internal circuit of AND gate as shown below.

From Wikibooks, open books for an open world. Because total VCC appears across transistors the drop across resistor R1 will be zero.

For more information about the AND gate in general, see this module. The arrangement of the CMOS components is shown below:. Views Read Edit View history. The chip is available hef081 different packages and is chosen depending on requirement. The chip is basically used where AND logic operation is needed.

Practical Electronics/IC/4081

Output of the AND gate is the voltage across resistor R1. The two inputs of AND gate are driven out from bases of the two transistors. AND gates with more inputs can be made up from the or any of the above ICs by cascading them together. Retrieved from ” https: At this time the total VCC appears across resistor R1.

A few mentioned below. When any one of the buttons is pressed.

Datashete a is not available, there are several ways to achieve an AND gate. The first method with require two ICs to implement, but a total of four gates can be made. The pinout diagram, given on the right, is the standard two-input logic gate IC layout:.

The four AND gates in the chip mentioned earlier are connected internally as shown in diagram heg4081.

Because of this the chip can be used for high speed AND operations. There datashset four AND gates in the chip, we can use one or all gates simultaneously.

Because output is nothing but voltage across resistor R1 it will be LOW. For realizing the above truth table let us take a simple AND gate application circuit as shown below. A selection of different manufacturers’ datasheets is given below:. It is really popular and is available everywhere.
