What are the key features of CD74HC390M96E4?
- Dual decade counter with independent divide-by-2 and divide-by-5 sections, enabling flexible BCD, binary, or divide-by-10 counter configurations from a single IC
- 20 MHz maximum count frequency with 50 pF load capacitance rating in HC-series CMOS for medium-speed frequency division and event counting applications
- 16-pin SOIC surface-mount package with load/preset input support, allowing programmable starting count values in timer and frequency divider circuits
What is CD74HC390M96E4 used for?
CD74HC390M96E4 is used in digital timing, frequency division, and event counting circuits requiring dual decade counters with BCD output. Its divide-by-2 and divide-by-5 sections can be cascaded internally or externally to produce divide-by-10 or divide-by-100 frequency chains in clock generation and period measurement applications. The 16-pin SOIC format integrates easily into compact PCB designs for industrial timers, frequency meters, and embedded control systems.

Frequently Asked Questions
What divide functions does CD74HC390M96E4 support and at what maximum frequency?
CD74HC390M96E4 supports independent divide-by-2 and divide-by-5 counter sections, which can be cascaded for a divide-by-10 function. The device operates at up to 20 MHz maximum count frequency with a 50 pF load capacitance rating.
How can CD74HC390M96E4 be configured for a divide-by-100 frequency chain?
Two CD74HC390M96E4 devices can be cascaded — first dividing by 10 per chip (combining divide-by-2 and divide-by-5 sections) — to create a divide-by-100 chain. This configuration generates a precise 100 Hz output from a 10 kHz input clock using 2 chips and minimal external wiring.
Does CD74HC390M96E4 support presettable counting and what package is it in?
CD74HC390M96E4 includes load/preset inputs allowing the counter to be initialized to a specific BCD value, enabling programmable timer and countdown applications. It is packaged in a 16-pin SOIC surface-mount housing measuring approximately 10 mm x 4 mm.
For a portable battery-powered timer, how does CD74HC390M96E4 compare to a microcontroller counter peripheral?
CD74HC390M96E4 provides hardware decade counting without firmware overhead, consuming as little as 80 µA at 5 V in quiescent mode versus a microcontroller's multi-milliamp active draw. For simple 20 MHz counting tasks, the dedicated IC reduces system complexity and power budget in battery-powered timer designs.
