4050 Buffer

The 4050 Buffer IC (CD4050) is a hex non-inverting buffer based on CMOS technology. It contains six independent buffer gates that pass the input signal to the output without inversion, while providing improved drive strength and signal stability. One of its key advantages is its ability to perform high-to-low voltage level shifting, making it especially useful for interfacing 5V systems with 3.3V microcontrollers.

Operating over a wide voltage range (3V–15V), the CD4050 is commonly used with Arduino, ESP32, ESP8266, and Raspberry Pi for signal buffering and logic level conversion.
