DM74AS161 Product details

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.

About Fairchild Semiconductor


Fairchild Semiconductor was a pioneering semiconductor company that was founded in the late 1950s.
The company was known for its innovation in the development of the first commercial transistor and for its contributions to the advancement of the integrated circuit technology.
Fairchild became a leading supplier of power semiconductors, analog and mixed-signal integrated circuits, and other semiconductor products.
The company was acquired by ON Semiconductor in 2016 and its products and technologies continue to be developed and sold under the ON Semiconductor brand.
