In the digital world, counters, dividers, and registers fulfill an often overlooked yet highly important purpose. These devices serve to store, count, and divide digital data, controlling the flow and use of digital information inside electrical circuits. It’s important to take a look at these devices and how they work, so that you can understand their application field and working principle. One such device is the CD74HC192PWE4.

The CD74HC192PWE4 is an 8-bit binary counter packed into a 16-pin PDIP package. It is a synchronous device, so all of its stages are advanced at once by providing a single clock pulse. Two independent clock inputs are available. The chip can be reset by assertive-low signals on its reset input terminals, making it ideal for use in digital counter and frequency dividing applications. This device is especially well-suited for digital logic applications such as industrial control and communication systems where a fast response time is desired.

The CD74HC192PWE4 uses an asynchronous reset-drive circuit to ensure the data entered into the device is placed in its true form regardless of the speed of the input data. Further, the output of this device is locked and latched regardless of its input logic level, preventing any unwanted output transitions. This makes the device suitable for clocked operations that require high speed data input as well as low power consumption.

The device operates with a synchronous reset function, which ensures that the data present on the output is in the same form as that entered into the device. Also, it features a built-in noise filter for eliminating any unwanted pulses or glitches that may be present on its inputs. This is especially useful in applications that require lower power consumption and fast response time.

So how does the CD74HC192PWE4 work? The device consists of an 8-bit synchronous counter, an asynchronous reset-drive circuit, and a noise filter. When the device is triggered with a clock pulse, the counter is incremented. If the reset input is asserted, the counter is immediately reset to zero. The device will continue to increment until the counter reaches its maximum count, at which point the overflow output is activated.

In addition, the device also features a built-in output latch. This allows the outputs of the device to remain in their current state, regardless of the logic level of the inputs. This is useful in applications where digital data is processed at different speeds and a constant output is desired. The device also includes built-in noise-filter circuitry which eliminates any unwanted pulses that may be present on its inputs, further ensuring the output of the device is consistent.

The primary application field and working principle of the CD74HC192PWE4 is to provide a fast, reliable and low power digital counter or dividing device. It is ideal for applications such as industrial control, communication circuits, and clocked operations that require consistent output. The device’s synchronous reset and noise-filter circuitry further increase the reliability of the device when used in such applications.
