74F160A • 74F162A
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. The F160A has an asyn-
chronous Master Reset input that overrides all other inputs
and forces the outputs LOW. The F162A has a Synchro-
nous Reset input that overrides counting and parallel load-
ing and allows all outputs to be simultaneously reset on the
rising edge of the clock. The F160A and F162A are high
speed versions of the F160 and F162.
