5.6. AND

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.
