Exclusive NOR Gates

<^< Exclusive-OR Gates | Course Index | Assessment: Semiconductors >^>

Exclusive-NOR gates will produce a logic 0 output whenever either one of the inputs is at logic 1 and the other is at logic 0. Exclusive-NOR gates produce a logic 1 output whenever both inputs have the same logical state (i.e., when both are at logic 0 or both are at logic 1). The Boolean expression for the output, Y, of an exclusive-NOR gate with inputs, A and B, is:

Y =

Logic 0, Logic 0 Logic 0, Logic 1 Logic 1, Logic 0 Logic 1, Logic 1
