Datasheft of this the chip can be used for high speed AND operations. The first is to use a NAND gate and invert the output. Because output is nothing but voltage across resistor R1 it will be LOW.

The four AND gates in the chip mentioned earlier are connected internally as shown in diagram below. Retrieved from ” https: The pinout diagram, given on the right, is the standard two-input logic gate IC layout:.

From Wikibooks, open books for an open world. The chip provides TTL outputs which are needed in some systems. Policies and datashfet Contact us. In this state the current flow through base of both transistors will be zero. These two inputs are connected to buttons to change the logic of inputs. The chip is basically used where AND logic operation is needed. Views Read Edit View history.

A few mentioned below. The first method with require two ICs to implement, but a total of four gates can be made. The truth table for one of the four gates is shown to the right. For better understanding the internal working let us consider the simplified internal circuit of AND gate as shown below. This chip is different in pinout to the TTL andbut can fulfill the function of either if the wiring is modified. The second will require only one IC, but only two gates can be made. It is datasheeet popular and is available everywhere.

When both buttons are pressed.

At this time the total VCC appears across resistor R1. Output of the AND gate is the voltage across resistor R1. The circuit working can be explained in few stages below: If a is not available, there are several ways to hef4018 an AND gate.

When any one of the buttons is pressed. These are available from manufacturers. AND gates with daasheet inputs can be made up from the or any of the above ICs by cascading them together.

After verifying the three states, you can tell that we have satisfied the above truth table. The two inputs of AND gate are driven out from bases dataheet the two transistors. This is discussed on this page. This LED is connected to detect the state of output. Submitted by admin on 6 April The dqtasheet is available in different packages and is chosen depending on requirement.

A selection of different manufacturers’ datasheets is given below:. Both transistors will be ON and voltage across both of them will be zero. The description for each pin is given below.
