The CD4033 is a high-performance decade counter IC with an integrated 7-segment decoder from the CD4XXX CMOS logic family, designed for efficient digital counting and direct display driving in electronic systems. Built using advanced CMOS technology, it delivers ultra-low power consumption, high noise immunity, and stable switching performance, ensuring reliable operation in industrial, embedded, and consumer applications.
Operating over a wide supply voltage range of 3V to 15V, the CD4033 provides excellent design flexibility compared to lower-voltage logic families. This wide operating range allows seamless integration into battery-powered systems as well as standard 5V and 12V digital circuits. Its CMOS architecture ensures minimal static power dissipation while maintaining accurate counting and display decoding functions.
The device combines a decade counter with a built-in 7-segment decoder/driver, allowing direct control of LED displays without the need for external decoding components. This reduces system complexity, saves PCB space, and improves overall efficiency. Its optimized internal design ensures low thermal generation, high reliability, and stable long-term performance even in continuous operation.
Available in DIP package form, the CD4033 is ideal for through-hole mounting, prototyping, and durable industrial PCB designs.
