4011 : 2-input NAND gates (easy IC )
Source :: http://www.doctronics.co.uk/4011.htm
Pin connections
The 4011 has four separate 2-input NANDgates which you can use independently.
Truth table
The truth table of each individual gate is:
input B | input A | output |
0 | 0 | 1 |
0 | 1 | 1 |
1 | 0 | 1 |
1 | 1 | 0 |
where '0' represents a LOW voltage, and '1' represents a HIGH voltage.
