74LS08 Quadruple Two Input AND Gate – Datasheet

74LS08 Quadruple IC is a member of the 74XXYY IC series. There are four AND gates in the chip and each gate has two inputs, hence the name Quadruple 2- Input AND Gate. IC 74LS08 uses only one single power supply and it also comes in multiple packages to solve the requirement according to the circuit. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers. The IC 74LS08 is smaller in size and it has a much faster speed which makes it reliable in every kind of device.

What is an AND Gate?

An AND Gate is a logical operator/circuit that gives a logical high (1) output only when all of its inputs are high (1), otherwise, it results in a logical low (0).
