4位同步二进制计数器 4-BIT SYNCHRONOUS BINARY COUNTERS
description
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.
