Simple Clockable Decoder Chip


Let's say we have an 8-Bit shift register. We reset it so that its
outputs are as follows:

00000000

We then set the data input high and clock it:

10000000

We then drop the data input low and continuously clock it:

01000000
00100000
00010000
00001000
00000100
00000010
00000001

This is done easily using two pins from a microcontroller, one pin for
the data input and another pin for the clock input.

I'm looking for something that will do the same job with just one pin
(i.e. a pin to clock it). That is to say, when you reset it, it
becomes:

10000000

and then when you clock it, it cycles thru the outputs:

01000000
00100000
00010000
00001000
00000100
00000010
00000001
10000000
01000000
01000000

I've googled a bit and the closest I've come to this specification is
the 4017 chip in the 4000 CMOS family. Here's a quick paragraph about
it:

The only problem though is that I need a chip that will count to 16
instead of 10. Does anyone know of a similar chip that will cycle thru
16 different outputs?

Then again I could always just use two of these chips, but I just
thought I'd check to see whether there was a more suitable chip out
there.
