2,124 views

CD4033 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4033 has a Decade of Counter

CD4033 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 a very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.

FS Technology PCBA Components is a leading Shenzhen PCB assembly manufacturer & Electronics Component Sourcing with 18 years of experience. FT Tech has served thousands of domestic and overseas companies in the past decades
