CD4002 NOR Gate Dual 4-Input
CD4002 NOR Gate Dual 4-Input in a cascade is called a NOR gate. The inclusive NOR (Not & OR) gate has an output that is normally at logic level 1 and only goes LOW to a logic level 0 when any of its inputs are at logic level 1. The Logic NOR Gate is the reverse or complementary form of the inclusive OR gate.
