CD4001 CMOS Quad 2-Input NOR Gate IC
The CD4001 is a quad gate, monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement mode transistors.It has equal source and sink current capabilities and conforms to the standard B series output drive. The devices also have buffered outputs which improve transfer characteristics by providing very high gain.
What is a NOR Logic Gate?
An OR gate followed by a NOT gate in a cascaded condition 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.
