HCF40103BE, 8-Bit Presettable Synchronous Down Counter, DIP-16

The HCF40103BE is an 8-bit presettable synchronous down counter, designed for applications requiring binary counting with preset functionality. It can operate as a standalone 8-bit counter or be cascaded for extended counting sequences. With an operating voltage range of 3V to 20V, this counter ensures compatibility with a wide range of logic families. The maximum clock frequency of 4.8 MHz allows for reliable operation in timing, frequency division, and event counting applications. The HCF40103BE includes synchronous and asynchronous preset modes, enabling precise control over counting operations. Its DIP-16 package makes it suitable for through-hole PCB designs, embedded control systems, and frequency measurement applications.
