CD74HC390E TI Counter IC | 16-PDIP | Dual Decade, 4-Bit Binary

Product Overview

The CD74HC390E from Texas Instruments is a high-speed CMOS dual decade counter and 4-bit binary counter integrated circuit. It contains two independent counters in a single 16-pin PDIP package, each configurable as a divide-by-2, divide-by-5, or divide-by-10 counter. Operating from 2V to 6V, it features low power consumption and high noise immunity, making it ideal for frequency division, timing, and counting applications in industrial and consumer electronics.
