4028 (BCD to Decimal Decoder)

Overview

The CD4028 is a monolithic CMOS BCD-to-Decimal decoder that converts a 4-bit Binary-Coded Decimal (BCD) input into one of ten mutually exclusive outputs. This IC is a staple in digital electronics, enabling the direct drive of decimal displays, relay drivers, and other control circuits. Its low power consumption and wide supply voltage range make it ideal for both battery-powered and industrial applications.
