What are the key features of CD4040BF?
- 12-stage ripple-carry binary up-counter with outputs from all stages accessible
- Wide supply voltage range of 3 V to 15 V compatible with both CMOS and TTL logic families
- High noise immunity of 45% VDD and low quiescent current typical of 4000 series CMOS
What is CD4040BF used for?
The CD4040BF is commonly used in frequency division, timer circuits, and event counting applications in industrial and instrumentation equipment. It serves as a prescaler or clock divider in systems where a low-frequency reference must be derived from a faster oscillator, such as dividing a 12 MHz clock down to sub-Hz frequencies across its 12 counting stages. The ceramic DIP package suits high-reliability and military-grade designs that demand extended temperature performance.

Frequently Asked Questions
How many counter stages does the CD4040BF provide and what is the maximum counting frequency?
The CD4040BF provides outputs from all 12 ripple-carry binary counter stages. At a 10 V supply it can operate with clock inputs up to 12 MHz, making it suitable for frequency division applications across a wide range of source oscillators. Lower supply voltages reduce the maximum clock frequency accordingly.
Which power supply voltage range does the CD4040BF support and how does that affect system compatibility?
The CD4040BF operates across a 3 V to 15 V supply range, which allows it to interface with both 5 V TTL-level logic and higher-voltage CMOS systems. At 5 V it is directly compatible with standard CMOS gates, while at 15 V it achieves higher switching speeds and improved noise margins of up to 45% of VDD.
Why choose the ceramic DIP package of the CD4040BF over a plastic package variant for harsh environments?
The ceramic 16-pin DIP package of the CD4040BF offers hermetic sealing, which protects the die from moisture ingress and contamination in temperatures ranging beyond the commercial -40 °C to +85 °C range. This makes it preferred for military, aerospace, and industrial applications where long-term reliability under thermal cycling and humidity stress is required.
