CD4040BCM

Counter Dividers Overview

The Fairchild Semiconductor CD4040BCM is a 12-stage asynchronous binary ripple carry counter implemented using advanced silicon-gate CMOS technology. It increments on the negative transition of the clock input and resets to zero via a dedicated reset pin. The device operates within a wide supply voltage range of 3.0V to 15V, offering high noise immunity and low power consumption compatible with TTL logic standards.

Counter Dividers Feature Summary

• Advanced silicon-gate CMOS construction for high speed and low power
• Asynchronous 12-stage binary counting with ripple carry output
• Negative edge triggered clock input with Schmitt trigger characteristics
• Independent asynchronous reset function

Counter Dividers Applications

• Frequency division circuits
• Digital timing sequences
• Event counting systems

Counter Dividers Procurement Notes

Verify the specific manufacturer datasheet for the CD4040BCM to confirm exact electrical parameters and package dimensions. Ensure compatibility with system voltage requirements and signal levels before integration. Cross-reference official documentation for any revisions or obsolescence notices.

Counter Dividers Selection Notes

Select this component for applications requiring a 12-bit asynchronous counter with CMOS compatibility. Consider the MM74HC4040J for HC series performance or other variants if different stage counts or packaging options are required by the design constraints.

Counter Dividers Part Context

This part belongs to the CD4000B series of CMOS digital logic devices. It shares functional similarities with the CD4060BC and CD4020BC counters but provides a specific 12-stage configuration. The 'BCM' suffix typically denotes a plastic DIP or SOIC package variant within the Fairchild product line.

Counter Dividers Replacement Considerations

The MM74HC4040J is a documented alternative from Fairchild. Verify pinout compatibility and voltage level differences between the standard CD4000B series and the HC/UH series before substitution.
