What are the key features of CD74HC390EE4?
- Dual independent decade counters with separate divide-by-2 and divide-by-5 sections allowing flexible cascading for divide-by-10, divide-by-100, or custom frequency division
- HC CMOS family operation from 2V to 6V supply enabling compatibility with both 3.3V and 5V digital systems with low quiescent current
- Up-counting operation with asynchronous master reset for easy initialization in clocking, timing, and event counting circuits
What is CD74HC390EE4 used for?
The CD74HC390EE4 is widely used for frequency division, clock generation, and event counting in digital systems including timers, frequency synthesizers, and real-time clock circuits. Its dual-counter architecture allows cascading to achieve divide-by-100 or custom modulus counters for multi-digit decade counter displays. The device also suits educational electronics and prototyping applications due to its through-hole PDIP package and simple clocking interface.

Frequently Asked Questions
What are the divide-by functions available in the CD74HC390EE4?
The CD74HC390EE4 contains two independent counter sections per package: a divide-by-2 (single flip-flop) and a divide-by-5 counter. These can be connected in series to form a decade (divide-by-10) counter, or used independently for custom frequency division requirements.
What is the supply voltage range and logic family of the CD74HC390EE4?
The CD74HC390EE4 belongs to the HC (High-speed CMOS) family and operates from 2V to 6V supply voltage, making it compatible with both 3.3V and 5V digital logic systems with low static power consumption typical of CMOS technology.
What package does the CD74HC390EE4 use?
The CD74HC390EE4 is available in a 16-pin PDIP (Plastic Dual Inline Package) through-hole package, suitable for breadboard prototyping, educational projects, and legacy PCB designs that use through-hole assembly.
Does the CD74HC390EE4 have a preset or load input?
The CD74HC390EE4 does not include a preset or parallel load input; it supports only asynchronous master reset to clear all counter stages to zero. For programmable count sequences or preset values, a device with synchronous load capability would be required.
