DM74AS161规格书详情
General Description
These synchronous presettable counters feature an internal carry look ahead for application in high speed counting designs. The DM74AS161 and DM74AS163 are 4-bit binary counters. The DM74AS161 clear asynchronously, while the DM74AS163 clear synchronously. The carry output is decoded to prevent spikes during normal counting mode of operation. Synchronous operation is provided by having all flip-flops clocked simultaneously so that outputs change coincident with each other when so instructed by count enable inputs and internal gating. This mode of operation eliminates the output counting spikes which are normally associated with asynchronous (ripple clock) counters. A buffered clock input triggers the four flip-flops on the rising (positive-going) edge of the clock input waveform.
