Key Features
- 16-stage programmable binary counter with internal RC oscillator enables time delays from microseconds to hours using a single external RC network
- Selectable output modes including single-cycle and auto-repeat allow one IC to replace discrete 555 timer circuits in both monostable and astable configurations
- Wide supply voltage range from 3 V to 15 V in the CMOS 4000 family provides compatibility with both 5 V logic and 9 V–12 V legacy system supply rails
Applications
CD4541BM96E4 is used in appliance control panels, industrial timers, and alarm systems where a long programmable time delay of up to several hours must be generated with a minimal component count of two external passives. Its programmable counter division ratio and auto-reset mode make it suitable for watchdog reset timers, periodic sensor sampling triggers, and sequential lighting controllers in consumer and industrial products. The wide 3 V to 15 V supply range also allows direct use in 9 V battery-powered remote control and security devices without a voltage regulator.

Frequently Asked Questions
How long a time delay can CD4541BM96E4 generate and what external components set the period?
CD4541BM96E4 can generate time delays from a few microseconds up to several hours by combining the internal RC oscillator frequency with the 16-stage binary counter's programmable division ratio. Only a single external resistor and capacitor connected to the RC pin set the oscillator period; selecting the 2^16 division gives a time-out roughly 65,536 times the oscillator period, enabling multi-hour delays with a 100 kΩ resistor and 10 µF capacitor.
What supply voltage does CD4541BM96E4 support and how does that affect its use in battery-powered designs?
CD4541BM96E4 operates from a supply voltage of 3 V to 15 V, making it directly compatible with a 9 V alkaline battery without a regulator and with 5 V TTL-logic systems. At 3 V supply the standby current remains in the microampere range, allowing months of battery life in low-duty-cycle timer applications such as periodic alarm wake-up circuits.
Can CD4541BM96E4 operate in a repeating pulse mode rather than a single-shot delay?
Yes, CD4541BM96E4 has a selectable auto-reset mode that automatically restarts the counter after each timeout, generating a continuous stream of output pulses with a period equal to 2^N times the RC oscillator period where N is 8, 10, 13, or 16 stages. This eliminates the need for external feedback logic to create a repeating timer, reducing the total circuit to the IC plus 2 passive components.
How does CD4541BM96E4 in a 14-pin SOIC compare to a 555 timer for a long-delay industrial timer application?
For delays beyond 10 seconds, CD4541BM96E4 requires a far smaller capacitor than a 555 timer because the internal 16-stage counter multiplies the RC period by up to 65,536 times. A 555 monostable achieving a 60-second delay needs a 100 µF electrolytic capacitor, while CD4541BM96E4 achieves the same delay with a compact 1 µF capacitor, reducing PCB area and eliminating the leakage-current accuracy problem of large electrolytic timing capacitors.
