... Synchronous Presettable BCD Decade Counter General Description The 74F160A and 74F162A are high-speed synchronous decade counters operating in the BCD (8421) sequence. They are synchronously presettable for applications in pro- grammable dividers. There are two types of Count Enable inputs plus a Terminal Count output for versatility in forming synchronous multistage counters ...

... Functional Description The 74F160A and 74F162A count modulo-10 in the BCD (8421) sequence. From state 9 (HLLH) they increment to state 0 (LLLL). The clock inputs of all flip-flops are driven in parallel through a clock buffer. Thus all changes of the Q outputs (except due to Master Reset of the (F160A) occur as a result of, and synchronous with, the LOW-to-HIGH transition of the CP input signal ...
