74HC390 Dual 4-Bit Decade Ripple Counter | High-Speed CMOS | DIP-16 Through-Hole

Description

The 74HC390 is a high-speed, silicon-gate CMOS Dual 4-bit Decade Ripple Counter. It contains two independent 4-bit decade counters, each consisting of a divide-by-two section and a divide-by-five section. These sections can be cascaded to create a BCD (Binary Coded Decimal) decade counter or used independently for various frequency division tasks.

Operating as a ripple counter, the internal flip-flops change state sequentially, making it a highly efficient solution for counting events or generating precise timing divisions. As part of the HC (High-Speed CMOS) logic family, the 74HC390 provides excellent noise immunity and low power consumption. The DIP-16 through-hole package is ideal for educational use, breadboarding, and traditional PCB assembly.
