BU4028B

Signal Switches, Multiplexers, Decoders Overview

The BU4028B is a BCD-to-decimal decoder manufactured by ROHM Semiconductor. It converts four-bit binary-coded decimal (BCD) input signals into ten distinct decimal output lines, designated Q0 through Q9. The device activates the specific output line corresponding to the active A-D input code while maintaining all other outputs in a low state. This component supports operation across a wide power supply voltage range and features high input impedance characteristics suitable for standard logic interfacing.
