The IC component 54F190LMQB is a high-speed 4-bit synchronous up/down binary counter. It is a part of the 54F family of integrated circuits, which are known for their high-performance and low-power consumption characteristics. Here is an overview of the key features of the 54F190LMQB IC component:
1. Synchronous Operation: The 54F190LMQB operates synchronously, meaning its outputs change simultaneously with the clock inputs. This makes it suitable for applications where precise timing is required.
2. Up/Down Counting: The IC component offers the flexibility to count up or down depending on the state of the up/down control input. This feature enables it to be used in a wide range of applications, such as frequency division, data manipulation, and address generation.
3. Asynchronous Parallel Load: The 54F190LMQB provides an asynchronous parallel load input (PL) that allows the user to load a predetermined value into the counter. This feature is useful for initializing the counter at a specific value upon power-up or when a specific condition is met.
4. Carry and Borrow Outputs: The IC component features carry (Cn) and borrow (Bn) outputs, which facilitate cascading multiple counters for higher bit-count applications. These outputs are used to carry or borrow from one counter to the next, enabling the creation of larger counter configurations
