Description: 1. The 74HC390 is a dual 4-bit ripple counter integrated circuit (IC) that can be used in various sequential logic applications within the Internet of Things (IoT) domain. 2. Each counter has a decade mode operation with a separate synchronous reset input (PR), enabling independent counting for each counter. 3. The 74HC390 features open collector outputs Q0 through Q3 on each counter, which can be easily interconnected to form larger counters or other digital logic circuits. 4. This IC has a compact design with low power consumption and is compatible with the TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal Oxide Semiconductor) logic families, making it suitable for a wide range of IoT projects. 5. The 74HC390 includes an enable input EN which can be used to stop or start the counter operation in each stage based on external control signals. 6. With a maximum clock frequency of 10MHz, the ripple counter IC is suitable for applications requiring moderate speed and f
