SYNCHRONOUS UP/DOWN COUNTERS WITH DOWN/UP MODE CONTROL

The CD54HC190 CD74HC190 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 (AD) 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 By Texas Instruments
