74HC390 Dual 4-bit Decade Ripple Counter IC

74HC390 Dual 4-bit Decade Ripple Counter IC

The 74HC390 is a dual 4-bit decade ripple counter IC in a DIP-16 or SMD package. It is designed to operate as a binary counter that counts from 0 to 9 (a decade) for each of the two independent 4-bit counters integrated within the IC. This feature makes it ideal for counting applications where decade counting (0-9) is required, such as in digital clocks, frequency dividers, or event counting systems. The 74HC390 operates in a ripple counter configuration, meaning that the carry-out from each stage triggers the next counter stage. This ripple effect causes a slight delay as the counter advances, but it is generally suitable for lower-frequency applications. The IC includes clear and reset functions, allowing both counters to be quickly reset to zero when needed. This is especially useful in timing or sequential logic circuits where you want to control the start of counting or reset the system for re-initiation. The IC operates with a CMOS logic family, which ensures low power consumption and high-speed operation, providing reliable performance in a wide range of systems. It works with supply voltages ranging from 2V to 6V, and it offers high noise immunity and low static power consumption, making it ideal for use in battery-powered devices or other power-sensitive applications.
