CD4068 8-input NAND/AND Gate
Package DIP Series CD4000 (CMOS)
CD4068 overview
CD4068 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4068 has an 8-input NAND/AND Gate
CD4068 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.
