**Purpose**

To perform a logical AND operation.

Mathematical description

The output becomes TRUE (=1) if all logical input signals are TRUE. If at least one input signal is FALSE, the output will become FALSE (=0).

**Parameters** 

None.

**Remarks** 

None.

**Examples** 

Table 1 presents the possible output values that can result from two input signals. Table 2 presents the possible output values that can result from three input signals.
