CD4028 CD4028BE 4028 BCD to Decimal Decoder IC
The CD4028BE (also known as 4028 IC) is a high-performance BCD-to-decimal decoder/driver from the CMOS logic family. It is designed to decode a 4-bit binary-coded decimal input (0 to 9) into one of ten active-low or active-high decimal outputs. Outputs 0–9 are uniquely activated depending on the BCD input, while all others remain inactive.
This IC is widely used in digital display systems, such as LED or LCD numerical displays, control panels, and memory addressing schemes in microprocessor and microcontroller systems. It is fully compatible with TTL inputs and operates on a wide supply voltage range (3V to 15V), making it highly flexible for both hobbyist and professional use.
Packaged in a DIP-16 format, the CD4028BE is breadboard-friendly and easy to prototype. You can use it with development platforms like Arduino, Raspberry Pi, or in combination with other ICs and electronic components.
