74HC390 Dual 4-bit Decade Ripple Counter IC DIP-16 Package
The 74HC390 is a dual 4-bit decade ripple counter IC in a DIP-16 package, designed to handle high-speed counting tasks in digital circuits. This IC integrates two independent 4-bit counters, each capable of counting from 0 to 9 (decade counting) or from 0 to 15 (binary counting). It is widely used in applications requiring binary or decimal counting, such as frequency division, time delay generation, and digital display driving. Each section of the 74HC390 is equipped with reset and clock inputs, offering precise control over the counting process. One section is configured as a divide-by-2 and divide-by-5 counter, making it particularly useful for applications that require decimal counting (base-10). The other section functions as a straightforward binary counter, counting from 0 to 15, providing flexibility for various digital counting needs. The IC’s asynchronous reset functionality allows users to reset the count instantly, which is essential for applications needing regular counter resetting, such as in pulse generation circuits.
