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 7432 is a quad two input OR gate with TTL levels.
The 74LS32 is a Quad Two Input OR gate with Low Power Schottky specifications.
The IC number for a NAND gate is typically 7400 for a standard quad 2-input NAND gate configuration. This IC contains four independent NAND gates, each with two inputs. Variants like the 74HC00 or 74LS00 are also common, offering different logic families with similar functionality.
quadruple means anything that has 4 of something in it. quad=4

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.
Pin 1 of the IC7402 is an output pin because it is part of a quad 2-input NOR gate configuration. Each NOR gate within the IC has specific input and output pins, and pin 1 corresponds to the output of the first NOR gate. The output pin provides the logical result of the NOR operation performed on the two input signals connected to the associated input pins.
