CD4011 NAND Gate : Pin Configuration & Its Applications

• The CD4011 is a two-input NAND gate integrated circuit. It is a quadrable NAND gate integrated circuit, which means that it contains four NAND gates in a single package. It is built with CMOS logic.
• The CMOS logic voltage level is used to design all inputs and outputs. It is used to execute NAND logic, but it can also perform ‘AND A= X x Y’ or ‘OR B = X+Y’ operations using a combination of four gates. NAND’s logical inputs and outputs. For throughput, I/O pins are buffered.
• CD4011 packages are available in 14-lead hermetic dual-in-line ceramic (F3A suffix), 14-lead dual-in-line plastic (E suffix), 14-lead small-outline (M, MT, M96, and NSR suffixes), and 14-lead thin shrink small-outline configurations (PWR suffix). CD4011s are also available in 14-lead thin shrink small-outline packages (PW suffix).

• D4011 NAND gates supplement the existing family of CMOS gates by providing the system designer with direct implementation of the NAND function.
• Now before we jump to the pin configurations and applications, first of all, let us understand what is a NAND gate and what functions does it serve?
• A NAND Gate is the logic gate that is the inverse of an AND gate. It is a common logic gate that is made up of AND and NOT gates. It is known as a “universal” gate in Boolean algebra because it can produce all other logic gates.
• A NAND gate is made up of one or more inputs and a single output. The NAND gate’s output is always logic 1 and only goes to logic 0 when all of the NAND gate’s inputs are logic 1. In other words, the NAND gate’s output is always true if at least one of its inputs is false.

• The NAND gate function is also known as the Sheffer Stroke function. If all of the NAND gate’s inputs are true, the output is false. It is represented by a symbol that looks like an AND gate with a circle on top, also known as an “inversion circle.”, as shown below.
