How does 74LS32 OR Gate work?

When all of its inputs are 0 (zero) or LOW, its output is 0 or LOW, whereas when at least one or both of its inputs are 1 or HIGH, its OUTPUT is going to be 1 or HIGH. In another sense, the OR gate function effectively finds the maximum between two binary digits, just as the AND function finds the minimum. It can be clearly seen that output X is only “0” (logic 0, low level) when both input A and input B are “0”. In other words, output X is equal to 0 when both input A and input B are 0. This device performs the boolean function Y = A + B or Y = (A \ • B \) \ in positive logic.

What is a logic gate?

Combinational logic devices are digital devices that convert binary inputs into binary outputs based on the rules of mathematical logic. These devices are commonly known as gates, as they control the flow of signals from inputs to a single output.

Normally all logic gates have one output and two inputs, some logic gates like NOT gate or inverter have only one input and one output. It is an electronic device with a boolean function or other functions like add or subtract, include or exclude according to its logical properties. They can be applied to electronic, electrical, mechanical, hydraulic and pneumatic technology. They are switching circuits integrated in a chip.

The low logic level represents zero volts and the high logic level represents 3 or 5 volts.

What is a logical level?

A logic level is defined as a specific state or voltage of a signal, we know that 0 and 1 are the two states of logic gates. Logic levels 0 and 1 are known as LOW and HIGH respectively. In digital electronics, these binary logic levels play a crucial role in data storage and transfer.

These logic levels can be thought of as on and off states. As mentioned above, logic levels are fed into the logic gate by the supply voltage.
