CD4012 Dual 4-input NAND Gate

Contents hide

CD4012 belongs to the CD4000 IC series. CD4012 IC is a 4-input NAND gate IC constructed using the monolithic complementary MOS (CMOS) integrated circuits. The N- and P-channel enhancement mode transistors provide a symmetrical circuit with output swings essentially equal to the supply voltage. The IC offers a wide variety of features such as high noise immunity and ESD barring. The IC always comes in a 14-pin hermetically sealed dual in line package. CD4012 is compact in size and is easily interfaceable with TTL, CMOS, and NMOS devices.

What is NAND Gate?

NAND gate is a digital logic gate most commonly employed in DLD applications. It is also sometimes referred to as a universal gate, as it can be used to implement any logic gate or expression in existence. If any one of the inputs to the NAND gate is set to high, the output of the gate will always be a logical low. On the other hand, a NAND gate will yield a logical high only when all of its inputs are set to LOW.
