CD4025 Triple 3-input NOR Gate
Series CD4000 (CMOS)
CD4025 overview
CD4025 belongs to 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4025 has a Triple 3-input NOR Gate
CD4025 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.
