7411 Triple 3-Input AND Gate Logic IC – 14-Pin DIP

The 7411 is a digital logic integrated circuit containing three independent 3-input AND gates in a single 14-pin package.

Each gate produces a HIGH output only when all three inputs are HIGH. If any one of the three inputs is LOW, the corresponding output remains LOW.

The 7411 is useful for digital control circuits, multi-condition logic, enable circuits, Boolean logic experiments, educational electronics, and breadboard prototyping.

AND Gate Logic Operation

Each gate contains three inputs: A, B, and C.

The output becomes HIGH only when Input A, Input B, and Input C are all HIGH simultaneously.

Applications

Suitable for multi-condition control circuits, digital interlocks, enable logic, Boolean logic circuits, alarm systems, signal gating, control systems, logic trainers, educational projects, and digital circuit prototyping.

The three-input configuration is particularly useful when an action should occur only after three separate digital conditions have all been satisfied.

Important Note

Exact supply voltage, input thresholds, output-current capability, propagation delay, switching characteristics, and power consumption depend on the specific 7411-series variant supplied, such as 7411, 74LS11, 74HC11, or 74HCT11.

Although these variants perform the same basic logic function, their electrical characteristics and compatible logic levels may differ. Always check the exact part number printed on the IC and its corresponding datasheet before use.
