description/ordering information
The 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.
When an overflow or underflow of the counter occurs, the MAX/MIN output, which is low during counting, goes
high and remains high for one clock cycle. This output can be used for look-ahead carry in high-speed cascading
(see Figure 1). The MAX/MIN output also initiates the ripple clock (RCO) output, which is normally high, goes
low and remains low for the low-level portion of the clock pulse. These counters can be cascaded using RCO
(see Figure 2).
If a decade counter is preset to an illegal state or assumes an illegal state when power is applied, it returns to
the normal sequence in one or two counts, as shown in the state diagrams (see Figure 3).
