16 bit to 4 digit 7 segment decoder

[TomS_]

Is something like a TIL311 or DIS1417 out of the question? All of the decoding is built in, and it includes the ability to latch data and blank as well, so you can use some of the control signals to ensure you get a stable display or block out anything you dont want to see.

They are really nice displays to look at too.

Power hungry though!
