description/ordering informationThe CD54/74HC190 are asynchronously presettable BCD decade counters, whereas the CD54/74HC191 and
CD54/74HCT191 are asynchronously presettable binary counters.
Presetting the counter to the number on preset data inputs (A−D) is accomplished by a low asynchronous
parallel load (LOAD) input. Counting occurs when LOAD is high, count enable (CTEN) is low, and the down/up
(D/U) input is either high for down counting or low for up counting. The counter is decremented or incremented
synchronously with the low-to-high transition of the clock.
