## Description

**EN13** is a 2-input EXCLUSIVE-NOR (XNOR) gate with 3x drive strength. An EXCLUSIVE-NOR (XNOR) gate is a digital logic gate with two inputs and one output. It behaves like an equality comparator, producing a HIGH output (1) only when both inputs are the same (either both HIGH or both LOW). If the inputs are different, it produces a LOW output (0).

The logic expression for a 2-input XNOR gate is:

Output = (A AND B) OR (NOT A AND NOT B)

It can also be represented using Boolean algebra as:

Output = A XNOR B = A’B’ + AB

In integrated circuits and digital systems, XNOR gates are often built using combinations of other basic logic gates such as NAND or NOR gates. They are widely used in various applications, including digital arithmetic, error detection, and memory storage circuits, among others.
