TC4028B is a BCD-to-DECIMAL decoder which converts BCD signal into DECIMAL signal. Of ten outputs from Q0 to Q9, one output corresponding to input BCD code goes to the “H” level and all the others remain at the “L” level. When D is used as inhibit input by use of three input lines from A to C, this decoder can be served as a BINARY-to-OCTAL decoder.
