CD4018BM Description

CD4018BM Description

The CD4018BM from Texas Instruments is a 5-bit Johnson counter with synchronous/asynchronous reset, designed for divide-by-N counting applications. Part of the 4000B series, this IC operates over a wide voltage range (3V to 18V), making it versatile for both low-power and industrial applications. Packaged in a 16-SOIC tube, it features positive-edge triggering, 8.5 MHz count rate, and asynchronous reset for flexible timing control. Its ROHS3 compliance and REACH unaffected status ensure environmental and regulatory suitability.

CD4018BM Features

  • 5-bit Johnson counter with synchronous timing for precise divide-by-N operations.
  • Wide supply voltage range (3V–18V), supporting mixed-voltage systems.
  • High-speed performance with 8.5 MHz count rate, ideal for frequency division.
  • Asynchronous reset for immediate state control, independent of clock input.
  • Positive-edge triggering ensures reliable synchronization in digital circuits.
  • Surface-mount (SOIC) packaging for compact PCB integration.
  • Last Time Buy status, indicating limited availability—suitable for legacy designs.

CD4018BM Applications

  • Frequency division in clock generation and signal conditioning circuits.
  • Sequential logic systems, such as shift registers and pattern generators.
  • Industrial control systems requiring reliable, low-power counters.
  • Consumer electronics, including timers and LED display drivers.
  • Legacy equipment maintenance, benefiting from its wide voltage tolerance.

Conclusion of CD4018BM

The CD4018BM is a robust, synchronous 5-bit counter offering high-speed operation, flexible reset control, and broad voltage compatibility. Its Johnson counter architecture makes it ideal for frequency division and sequential logic, while its surface-mount package ensures easy integration. Though marked as Last Time Buy, it remains a reliable choice for legacy and low-power designs requiring precision timing. Engineers should consider this IC for divide-by-N applications where performance and versatility are critical.
