CD4070 Quad EXCLUSIVE-OR Gate
Series CD4000 (CMOS)
CD4070 overview
CD4070 belongs to 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4070 has Quad EXCLUSIVE-OR Gate
CD4070 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.
