Applications

* The LS160A and LS162A count modulo 10 (BCD). The LS161A and LS163A count modulo 16 (binary. ) The LS160A and LS161A have an asynchronous Master Reset (Clear) input that overrides, and is independent of, the clock and all other control inputs. The LS162A and LS163A have a Synchronous Reset (Clear) in
