Overview
The CD4028BMG4 is a dual 4-bit BCD full adder integrated circuit produced by Texas Instruments. This component is part of the CD4028B series, which is designed for arithmetic operations in digital systems. The CD4028BMG4 is packaged in a 16-lead small-outline integrated circuit (SOIC) package, making it suitable for a variety of applications where space is a consideration.
Although the CD4028B series has been discontinued for new designs, existing stock and legacy systems may still utilize this component. It is important to note that Texas Instruments has discontinued the production of this device, and it is marked as obsolete for new designs.
