The 74HC161DB,118 is a synchronous presettable 4-bit binary counter, counter divider and divide-by-eight counter. This device can be used to count from zero to fifteen with five discrete inputs, or it can be used as a divide-by-eight counter with four discrete inputs. This is a rather versatile device as it can be used in a wide range of logic, counter, and divider applications.

The 74HC161DB,118 is composed of four identical 4-bit counters, interconnected so that increments and decrements will cascade from bit 0 through bit 3. All inputs have hysteresis, allowing smaller input numbers to be used. Additionally all outputs are open-drain types, allowing multiple devices to be connected in a wired-OR configuration to obtain a wider binary count span.

The main application of the 74HC161DB,118 is that it provides an easy way to create digital dividers such as frequency dividers, divisors and various other forms of dividers. For example, a frequency divider can be made using two of the 74HC161DB,118 devices and cascading the carry output from one to the enable of the other. You can then use the outputs from the second device as the new divided frequency output.

The 74HC161DB,118 is also very useful for counting applications. To count a particular number of pulses the device can be preset to the number of pulses to count then the external pulses will increment or decrement the count depending on the direction set by external inputs. This makes it easy to count and store the pulse count in a static environment.

One of the most beneficial features of the 74HC161DB,118 is its internal circuitry. The device contains four 4-bit synchronous counters, each of which is enabled by an input signal allowing the user to control when counting begins. There are also two outputs which let the user know when the device reaches certain count values. This allows the user to have an even greater level of control when using the device.

The 74HC161DB,118 is a very useful and versatile device. With its wide range of applications, it can provide a great deal of functionality to any project. Its built-in logic and presettability make it ideal for use in frequency dividers, counters, and other applications where counting and dividing are necessary.
