CD4009 CMOS Hex Buffers/Converter IC DIP-16 Package

The CD4009 is a CMOS hex buffer and logic-level converter IC in a DIP-16 package. It contains six independent buffers that can shift logic levels between different voltage domains, making it essential for interfacing 5V and 3.3V systems. This IC is widely used by makers, students, and engineers in India for reliable signal conditioning.
