CD54ACT191, CD54AC191, Presettable Synchronous 4-Bit Binary Up/Down Counter
The CD54AC191 and CD54ACT191 are asynchronously presettable binary up/down synchronous counters that utilize Advanced CMOS Logic technology.
Presetting the counter to the number on preset data inputs (P0-P3) is accomplished by setting LOW the asynchronous parallel load input (PL).
Counting occurs wh
