SN74LV163A 4 位同步二进制计数器
The ’LV163A devices are 4-bit synchronous binary counters designed for 2-V to 5.5-V VCC operation.
These synchronous, presettable counters feature an internal carry look ahead for application in high-speed counting designs. The ’LV163A 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
