CD4066 Quad Bilateral Switch
Package SOIC, SOP, PDIP Series CD4000 (CMOS)
CD4066 overview
CD4066 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4066 has Quad Bilateral Switch
CD4066 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.
