7408 Quad 2-Input AND Gate Logic IC – 14-Pin DIP
The 7408 is a digital logic integrated circuit containing four independent 2-input AND gates in a single 14-pin package.
Each AND gate produces a HIGH output only when both inputs are HIGH. If either input is LOW, the output remains LOW.
The 7408 is commonly used for digital logic experiments, control circuits, signal gating, educational electronics, breadboard prototyping, and general-purpose digital systems.

Applications
Suitable for digital control circuits, signal gating, enable/disable logic, Boolean logic experiments, alarm systems, switching circuits, logic trainers, embedded-system interfacing, educational projects, and breadboard prototyping.
AND gates are particularly useful when an output or action should occur only when multiple required conditions are simultaneously true.
Important Note
Exact supply voltage, logic thresholds, output-current capability, propagation delay, and power consumption depend on the specific 7408-series variant supplied, such as 7408, 74LS08, 74HC08, or 74HCT08.
Although these variants perform the same basic AND logic function, their electrical characteristics and compatible logic levels may differ. Always check the exact IC marking and corresponding datasheet before use.
