1. XOR and XNOR Logic Gates

2. XOR Function Output Y is TRUE if input A OR input B are TRUE Exclusively, else it is FALSE. Logic Symbol  Description  Truth Table  Boolean Expression  Y = A B Y XOR Y = Equivalent Expression

3. XNOR Function Output Y is FALSE if input A OR input B are TRUE Exclusively, else it is TRUE. Logic Symbol  Description  Truth Table  Boolean Expression  A B Y XNOR Y = Equivalent Expression Y =

4. Binary Half-Adder Single Bit Half-Adder A B SUM 0 0 + 0 1 0 1 A B SUM 0 1 0 1 + 1 0 + 1 1 + CARRY Carry

5. Binary Half-Adder with AOI Logic Single Bit Half-Adder A B SUM 0 1 0 1 A B SUM 0 1 OR A NOT AND B NOT SUM CARRY AND CARRY Carry

6. Binary Half-Adder with XOR Logic Single Bit Half-Adder A B SUM 0 1 0 1 X Y SUM 0 1 CARRY Carry SUM A B CARRY
