It is a direct drive chip. Not multiplex. There are many multiplexed chips available. I am not sure what the 4028 would do.
The chip you have could be used to multiplex, but you would need high power drivers for the commons (CC or CA read the data sheet) You CPU would then control the muliplexing. |
