Its a very versatile chip. It can be used in many places where logic control is required. As there are four identical NOR gates in one package, the inputs and outputs can be configured to make up quite complicated logic gates.
Being a NOR gate, the the output will be at supply level, until one or both of the inputs are taken high. At which point the output will go low.
The uses are many and varied. The 4000 series of chip are CMOS, so they can work at voltages between 5 and 12volts at low current.
It's a "quad, 2 input nor gate". To understand the significance of a "nor" gate, you need to understand a little about digital logic. An "or" gate takes 2 or more digital inputs and if either is "on", the output will be on. (asserted high). A "nor" gate inverts the output of the "or" gate, meaning that when either of the outputs are "on", the output will be "off" (asserted low). The two input part of the description just indicates that it only accepts two inputs. So, simply stated: If either (or both) input(s) of a quad, 2 input nor gate is (are) asserted high, the output will be low. If both inputs are off (low), the output will be high.

the easiest way to make an xnor gate is with a 7486 (or equivalent) integrated circuit, a quad xor gate. connect the output of one gate to one in put of another gate. connect the other input of the second gate to Vcc. the second xor gate will then act as an inverter.
I've seen a Logic chip, 2 input quad NAND gate IC, that was set up as a Audio amplifier circuit.
A Quad 2-input NAND Gate is a computer chip. It contains four copies of a 3 terminal circuit that takes two logic inputs (0 5v) and outputs the NAND combination according to the table: In A In B Out C 0 0 1 0 1 1 1 0 1 1 1 0 This happens to be the most fundamental of Boolean logic circuits in that it has been shown to be possible to build any desired logic circuit using only 2 input NAND gates. Indeed, one computer of the early days with which I am familiar - the Elliott / NCR 4100 - was in fact implemented using only NAND gates.This lemma is known as the Schmidt Orthogonality Principle. The Quad 2 Input NAND Gate is also the first chip built of what has become the universal chip family used in building logic circuits since the late 1960's, in the form of the 7400 part from Texas Instruments. Accompanied on introduction by the 7402 (Quad 2 Inpout NOR Gate), 7404 (hex inverter), and several others. These are typically found as the 14 pin DIP (DUal In-line Package), a black plastic or ceramic part 0.3" wide and 0.8" long with 7 pins at 0.1" spacing on each side.
