7412 Triple 3-Input NAND Gate

7412 Triple 3-Input NAND Gate package contains three independent positive logic, three input NAND GATES. Pins 14 and 7 provide power for all three logic gates. Outputs of one gate can be connected to inputs of another within the same chip or to another chip as long as they share the same ground.

NAND GATE Logic-Rules:

The same basic rules apply for the triple input NAND gate as in other more common 2-input variants. If the three inputs are labeled A, B, and C and the output = X, then the states can be modeled by the following chart:

A*B*C = X
0*0*0=1
0*0*1=1
0*1*0=1
0*1*1=1
1*0*0=1
1*0*1=1
1*1*0=1
1*1*1=0
