CD54HC192 - Presettable Synchronous 4-Bit Up/Down Counters
The ’HC192, ’HC193 and ’HCT193 are asynchronously presettable BCD Decade and Binary Up/Down synchronous counters, respectively.
Presetting the counter to the number on the preset data inputs (P0-P3) is accomplished by a LOW asynchronous parallel load input (PL).
The counter is incremented on the lo
