SN54197 50/30/100Mhz 可预设十进制或二进制计数器/锁存器
These high-speed monolithic counters consist of four d-c coupled, master-slave flip-flops, which are internally interconnected to provide either a divide-by-two and a divide-by-five counter (’196, ’LS196, ’S196) or a divide-by-two and a divide-by-eight counter (’197, ’LS197, ’S197). These four counters are fully programmable; that is, the outputs may be preset to any state by placing a low on the count/load input and entering the desired data at the data inputs. The outputs will change to agree with the data inputs independent of the state of the clocks.
During the count operation, transfer of information to the outputs occurs on the negative-going edge of the clock pulse
