Overview
The 74HC390PW,112, produced by Nexperia USA Inc., is a dual 4-bit decade ripple counter integrated circuit. This device is part of the 74HC and 74HCT series, known for their high-speed CMOS logic and compatibility with TTL logic levels. The counter is divided into four separately clocked sections, each containing two divide-by-2 and two divide-by-5 sections. This configuration allows for various counting modes, including BCD decade and bi-quinary decade operations. The device features asynchronous master reset inputs and separate clock inputs for each section, enabling flexible counting and frequency division applications.
