The pinout diagram, given on the right, is the standard two-input logic gate IC layout:. The truth table for one of the four gates is shown to the right.

For more information about the AND gate in general, see this module. The arrangement of the CMOS components is shown below:.


Datasjeet chip is different in pinout to the TTL andbut can fulfill the function of either if the wiring is modified. If a is not available, there are several ways to achieve an AND gate.

The first is to use a NAND gate and invert the output. The first method with require two ICs to implement, but a total of four gates can be made. The second will require only one IC, but only two gates can be made.

Practical Electronics/IC/4081

AND gates with more inputs can be made up from the or any of the above ICs by cascading them together. This ehf4081 discussed on this page.

These are available from manufacturers. A selection of different manufacturers’ datasheets is given below:.
