CD4541BNS

Overview

The CD4541BNS is a high-voltage CMOS programmable timer integrated circuit manufactured by Texas Instruments. It features a 16-stage binary counter, an RC-controlled oscillator, and automatic power-on reset logic. The device operates on a supply voltage range of 3V to 18V and supports surface-mount installation in a 14-SOIC package. It functions as a frequency divider or single-shot timer with an oscillator frequency range extending from DC to 100kHz.

Feature Summary

• 16-stage binary counter with selectable divide-by-N ratios
• RC-controlled oscillator supporting frequencies up to 100kHz
• Automatic power-on reset circuit for reliable initialization
• Wide operating voltage range of 3V to 18V

Applications

• Clock and timing control circuits
• Fan speed simulation and natural wind effect controllers
• Long-duration delay timers

Part Context

The CD4541BNS belongs to the CD4500B series of high-voltage CMOS logic devices. It is the surface-mount variant (SOIC-14) of the through-hole CD4541BE. This component is part of the standard CD4541 family, providing equivalent functionality to other manufacturers' MC14541 parts within the same electrical specifications.

Replacement Considerations

The CD4541BM serves as a direct pin-compatible alternative in SOIC-14 packaging. For through-hole requirements, the CD4541BE is the corresponding DIP-14 version. Cross-manufacturer equivalents such as the MC14541 are functionally compatible.
