SN54HC163 同步 4 位二进制计数器
These synchronous, presettable counters feature an internal carry look-ahead for application in high-speed counting designs. The ’HC163 devices are 4-bit binary counters. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when instructed by the count-enable (ENP, ENT) inputs and internal gating. This mode of operation eliminates the output counting spikes normally associated with synchronous (ripple-clock) counters. A buffered clock (CLK) input triggers the four flip-flops on the rising (positive-going) edge of the clock waveform.
These counters are fully programmable; that is, they can be preset to any number between 0 and 9 or 15
