7411 logic resource count How many individual AND gates are provided inside a 7411 integrated circuit, and what type are they?

Introduction / Context:
Classic 74xx logic ICs package multiple gates of the same type. Knowing how many gates are in a package helps with resource planning on a board and simplifies schematic capture. The 7411 device is a common part in the TTL family used for multi-input logic functions.

Given Data / Assumptions:

• Device identifier: 7411.
• Standard TTL family naming conventions apply.
• 14-pin DIP package assumed.

Concept / Approach:
The 7411 is a “triple 3-input AND” IC. That means it contains three independent AND gates, each with three inputs and one output. This organization is useful when combining multiple conditions without cascaded two-input gates, reducing propagation delay and pin count.

Step-by-Step Solution:

Verification / Alternative check:
Pinout references show three outputs and nine input pins distributed across the package, consistent with three 3-input gates plus power pins (VCC, GND).

Why Other Options Are Wrong:

• 1 or 2 or 4: Do not match the standard configuration of the 7411; 7408 would be four 2-input AND gates, not applicable here.

Common Pitfalls:
Confusing 7411 with 7408 (quad 2-input AND) or assuming all “74xx AND” parts are quad. The “11” specifically indicates triple 3-input AND in the legacy numbering scheme.
