Exclusive NOR Gate Animation

  The logic gate is a digital circuit with one or more inputs, with only one outputs. The gate can be constructed from diodes, transistors, and resistors. The logic gate is designed to perform a particular logical operation or function. Any logic gate operation can be easily understood with the help of truth table. A voltage in a digital circuit is said to be at the logic level 0 or logic level 1, depending on its actual numeric value. Sometimes logic 0 and logic 1 may be represented as power supply +5V Dc.

Logic  0	Logic 1
False Off Low No Open switch	True On High Yes Close switch

Exclusive-NOR gate This is an EX-OR  gate with the output inverted by the NOT Gate on the output. The output Y is true if inputs A and B are the SAME (both HIGH or both LOW ): Y = (A AND B) OR (NOT A AND NOT B) EX-NOR gates can only have 2 inputs.


The 74HC7266 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky Transistor  TTL (LSTTL).  The 74HC7266 provide the EXCLUSIVE-NOR function with active push-pull output.   IC 74266 EX-NOR pdf
