Key Features
- 7-stage binary ripple counter provides divide-by-2 through divide-by-128 outputs from a single IC
- Clocks at up to 20 MHz with 50 pF load, supporting wide-range frequency division in CMOS HC logic
- 14-pin DIP package facilitates rapid prototyping and through-hole assembly in low-cost designs
Applications
The CD74HC4024E is used in frequency division, clock generation, and timer circuits where binary division ratios from 2 to 128 are needed. Embedded system designers use it to derive slower clock signals from a high-frequency oscillator, reducing system clock rates for peripherals operating below 20 MHz. It also appears in event counters and timekeeping circuits in consumer electronics, industrial controllers, and educational electronics kits.

Frequently Asked Questions
What division ratios does the CD74HC4024E support and at what maximum clock frequency?
The CD74HC4024E is a 7-stage binary ripple counter that provides division ratios of 2, 4, 8, 16, 32, 64, and 128 from its Q1 through Q7 outputs. It operates at a maximum clock frequency of 20 MHz with a 50 pF load capacitance, making it suitable for deriving a range of sub-frequencies from a high-speed oscillator in digital timing circuits.
How does the CD74HC4024E perform in a 5 V breadboard prototype compared to CMOS 4000-series counters?
The CD74HC4024E operates across a 2 V to 6 V supply range, and at 5 V it clocks at up to 20 MHz—several times faster than the 4020B or 4024B CMOS 4000-series parts which typically max out at 3 MHz to 5 MHz. The 14-pin DIP package fits standard breadboards, and HC-family logic drives more output current, simplifying LED or buffer driving without extra stages.
When would a procurement engineer select the CD74HC4024E over the SMD SOIC variant for a production run?
A procurement engineer selects the CD74HC4024E DIP-14 through-hole version for prototyping, repair-friendly designs, or low-volume production where hand soldering is preferred over SMT reflow. For high-volume automated assembly, the SOIC variant saves board area and improves pick-and-place efficiency, so the DIP version is typically specified only when manual assembly or socketing for field replacement is required.
