The IC component HEF4518BT652 is a CMOS dual up counter. It is widely used in electronic circuits and systems for counting and timing applications. Here's an overview and key features of this IC component:
1. Package Type: HEF4518BT652 comes in a 16-pin SO package, which is compact and suitable for various circuit designs.
2. Supply Voltage Range: The operating supply voltage range of this IC is between 3V and 15V, making it compatible with a wide range of power sources.
3. Counting Capability: HEF4518BT652 has two separate counter sections, labeled as Counter A and Counter B. Each counter can count up to 16 binary digits (0-15), and the total counting range is from 0 to 30 due to overflow conditions. It offers a reliable and efficient counting solution for numerous applications.
4. Clock Inputs: The IC features clock inputs (pin 6 for Counter A and pin 9 for Counter B) that trigger the counting process. A positive-going transition (from low to high) on the clock inputs increments the counters.
5. Reset Inputs: It includes asynchronous reset inputs (pin 3 for Counter A and pin 12 for Counter B) for resetting the respective counters to zero. When a low signal is applied to the reset inputs, the counters are reset immediately.
6. Parallel Loading: A parallel loading capability is available for both counters
