- Integrated RC oscillator with external timing components for standalone timer operation without additional clock source
- Wide supply voltage range from 3V to 15V covering both CMOS and battery-powered application requirements
- Auto-reset and single-cycle modes enable both repeating and one-shot timing functions in a single 14-pin PDIP device
Applications
The CD4541BEE4 is used in timing and delay circuits, watchdog timers, and periodic event generation in consumer electronics, appliances, and industrial control systems. Its programmable divide ratios allow a single device to generate timing intervals from microseconds to hours using simple external RC components. Common applications include power-saving sleep timers, sequential control systems, and clock signal generation where a simple low-cost CMOS solution is preferred over microcontroller-based timing.

Frequently Asked Questions
What is the maximum operating frequency of the CD4541BEE4?
The CD4541BEE4 has a maximum operating frequency of 1.5MHz at nominal supply voltage. This refers to the maximum clock input or internal oscillator frequency. The 16-stage binary counter divides this frequency by selectable ratios, allowing the output period to be programmed from very short intervals to extremely long timing cycles depending on the divide ratio and oscillator frequency selected.
What supply voltage range does the CD4541BEE4 support?
The CD4541BEE4 is a CMOS 4000 family device that operates over a wide supply voltage range, typically from 3V to 15V. This wide range makes it compatible with 3.3V, 5V, 9V, and 12V power systems, and suitable for battery-powered designs. Power consumption is very low in static CMOS operation, making it ideal for energy-sensitive timing applications.
What package does the CD4541BEE4 use and what does the E4 suffix mean?
The CD4541BEE4 is packaged in a 14-pin PDIP (Plastic Dual In-line Package), as indicated by the JESD-30 code R-PDIP-T14. The E4 suffix denotes that this is a RoHS-compliant lead-free device (JESD-609 e4). The PDIP package allows through-hole soldering and is compatible with standard 0.3-inch breadboards and DIP sockets, making it ideal for prototyping.
How do you set the timing period for the CD4541BEE4?
The timing period of the CD4541BEE4 is set by three factors: external RC timing components connected to the oscillator pins, a 2-bit select pin (MS1/MS2) that selects the counter output stage (dividing by 2^8, 2^10, 2^13, or 2^16), and an AR pin for auto-reset mode. The output period equals the RC oscillator period multiplied by the selected divide ratio, allowing timing from microseconds to hours.
What are typical applications for the CD4541BEE4?
The CD4541BEE4 is commonly used in power-on delay timers, periodic interrupt generation, watchdog circuits, and sequential timing in household appliances and industrial equipment. It is also used in LED flashers, alarm systems with programmable delays, and low-power sleep/wake timers where a simple CMOS solution is preferred over a microcontroller. Its 3V to 15V range makes it compatible with diverse power supply environments.
