The MC14028B decoder is constructed so that an 8421 BCD code  
on the four inputs provides a decimal (one–of–ten) decoded output,  
while a 3–bit binary input provides a decoded octal (one–of–eight)  
code output with D forced to a logic “0”. Expanded decoding such as  
binary–to–hexadecimal (one–of–16), etc., can be achieved by using  
other MC14028B devices. The part is useful for code conversion,  
address decoding, memory selection control, demultiplexing, or  
readout decoding.
