74HC191 (4-Bit Counter) h2 spring oscillatorIntroduction : 74HC191 is an asynchronously presettable 4 bit binary up down counter. It contains fourmaster slave flip flops with internal gating and steering logic to provide asynchronous preset andsynchronous count up and count down operation. Asynchronous parallel load capability permitsthe counter to be preset to any desired value. Information present on the parallel data inputs (D0to D3) is loaded into the counter and appears on the outputs when
