The 74xx16y are 4 bit loadable counters.  2 are binary, 2 are decimal.
I think 1 of each pair has a synchronous reset/clear, the other is async.

Mouser has the 74AC161 and 74AC163 in stock.  They are binary.
I think you need an inverter to hook up the ripple carry out to load them to 
6 to make a divide by 10.
