Key Features
- 16-stage programmable binary counter timer operating up to 1.5 MHz clock frequency for precise long-duration timing intervals
- High-voltage CMOS rated to 20V supply enabling direct use with industrial and automotive 12V or 15V system rails
- Selectable output timing modes with auto-reset supporting one-shot and free-running timer configurations without external flip-flops
Applications
The CD4541BE is used in industrial timers, appliance delay circuits, and watchdog timeout generators where programmable long-period timing up to millions of clock cycles is needed from a simple RC oscillator. Its 16-stage counter divides an external RC or crystal clock to produce output periods from microseconds to many seconds, covering power-on delay, alarm timing, and sequential control in 5V to 20V systems. The 14-pin DIP package allows easy prototyping and through-hole assembly in cost-sensitive industrial control and consumer appliance boards.

Frequently Asked Questions
What is the maximum clock frequency the CD4541BE accepts, and how does the 16-stage counter extend the output timer period?
The CD4541BE accepts clock inputs up to 1.5 MHz at its nominal supply voltage. The internal 16-stage binary counter divides the clock by up to 65536, so a 1 MHz clock produces output periods from 1 µs at divide-by-1 tap to approximately 65.5 ms at the full 16-stage output, enabling long delays from a compact RC oscillator in industrial timer and alarm circuits.
How does the CD4541BE's 20V supply rating benefit designs powered from 12V automotive or industrial rails?
The CD4541BE CMOS high-voltage rating to 20V allows direct connection to 12V automotive ignition systems and 15V industrial sensor supply rails without a voltage regulator. This reduces BOM cost and eliminates a power conversion stage in battery-backed timer circuits and appliance control boards where 5V regulators would otherwise be required for standard CMOS logic.
In a low-cost watchdog timer circuit, when is CD4541BE preferable to a dedicated microcontroller watchdog peripheral?
The CD4541BE is preferable when no microcontroller is present in the design, or when an independent hardware timer is required to reset a microcontroller that may itself lock up. Its 16-stage binary counter generates timeout periods up to tens of seconds from a simple RC network at 4mA output drive, making it a self-contained, low-cost watchdog for industrial relay panels and appliance controllers that do not justify a full MCU solution.
