CD4011 Quad 2-input NAND Gate

Contents hide

The CD4001BC and CD4011BC quad gates are monolithic complementary MOS (CMOS) integrated circuits constructed with N- and P-channel enhancement mode transistors. They have equal source and sink current capabilities and conform to standard B series output drive. The devices also have buffered outputs which improve transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.

What is NAND Gate?

The NAND gate is a digital logic gate that is used readily in digital electronics. NAND gate is also known as a universal gate as it can be used to mimic the behavior of any digital logic gate in existence. The output of a NAND gate will always be LOW if any one of its inputs is high. The gate will yield a high output only when all the inputs to the gate are LOW.
