What are the key features of CD40110B?
- CMOS up/down decade counter with 7-segment decoded outputs for direct display drive
- Wide supply voltage range of 3V to 15V for versatile system integration
- Latch enable input for freezing display output without halting counting operation
- Carry and borrow outputs allow cascading multiple devices for multi-digit counting
- Low quiescent current consumption typical of CMOS logic family
What is CD40110B used for?
The CD40110B is ideal for digital panel meters, frequency counters, and industrial event-counting displays where a decoded BCD output drives 7-segment LEDs or LCDs directly. Its presettable up/down capability suits bidirectional counting applications such as inventory tracking, production line counters, and timer circuits. The wide 3V to 15V operating range makes it compatible with both legacy TTL-level and modern low-voltage embedded systems.

Frequently Asked Questions
What supply voltage range does the CD40110B support, and how does that affect system design?
The CD40110B operates from 3V to 15V, making it compatible with both 5V TTL-level logic and higher-voltage CMOS systems. This 3V to 15V range allows designers to use a single device across battery-powered and industrial supply environments without level-shifting circuitry.
How many CD40110B devices can be cascaded for multi-digit display applications?
Multiple CD40110B counters can be cascaded using the carry and borrow outputs; each device handles 1 decade (0–9), so a 4-digit display requires 4 cascaded ICs. The Dual-In-Line package with 16 pins simplifies PCB routing for chained counter stages.
Which display types are directly compatible with the CD40110B decoded outputs?
The CD40110B decoded 7-segment outputs drive common-cathode LED displays and LCD panels directly, eliminating external decoder ICs. At a 5V supply the outputs can source or sink sufficient current for standard 20 mA LED segment currents with appropriate series resistors.
When would the CD40110B latch enable input be used in a practical counter design?
The latch enable input freezes the 7-segment display at the current count while the counter continues incrementing internally, which is essential in frequency-counter designs where the display must hold steady for at least 1 second between updates to remain readable.
