Description

IC 7408 Quad 2 input AND Gate IC

The 7408 is a high-speed CMOS Logic Quad AND Gate. 7408 contains Four independent AND gates in one package. An AND gate is a digital logic gate with two or more inputs and one output that performs logical conjunction. The output of an AND gate is true only when all of the inputs are true. If one or more of an AND gate’s inputs are false, then the output of the AND gate is false.( Click for wide range of  Logic Gates at solicstores.in).

The 74HC08 provides four independent 2-input AND gates with standard push-pull outputs. The device is designed for operation with a power supply range of 2.0V to 6.0V.

Pin configuration

Internal structure  7408 IC

The four AND gates in the chip mentioned earlier are connected internally as shown in the diagram below.

Each AND gate here performs AND operation for two logic inputs. For example, gate1 performs AND operation between A1 and B1 and provides an output at the Y1 terminal.

The truth table of AND gate is given as,
