CD4040BCMX

Counter Dividers Overview

The CD4040BCMX is a 12-stage ripple carry binary counter manufactured by onsemi, housed in a 16-lead Small Outline Integrated Circuit (SOIC) package. It operates within a supply voltage range of 3.0V to 15V and features a Schmitt trigger clock input for high noise immunity. The device advances one count on the negative transition of each clock pulse and resets to zero via a logical high at the reset input. Maximum clock frequency reaches 12 MHz at 15V, with typical propagation delays ranging from 75 ns to 550 ns depending on voltage.

Counter Dividers Feature Summary

• Features a Schmitt trigger clock input to ensure high noise immunity during signal transitions.
• Provides independent asynchronous reset functionality that forces the counter to zero regardless of clock state.
• Offers wide supply voltage compatibility suitable for diverse power environments.

Counter Dividers Applications

• General-purpose digital counting applications
• Frequency division circuits
• Timing sequence generation

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'X' corresponds to tape and reel packaging when sourcing this component. Confirm the manufacturer origin as Fairchild Semiconductor or its successor entity onsemi. Ensure the package designation matches the 16-lead SOIC form factor required for your PCB layout. Cross-reference the datasheet revision date to confirm electrical characteristics remain consistent with your design requirements.

Counter Dividers Selection Notes

Select this component for designs requiring a compact 12-stage binary counter solution. The SOIC package facilitates surface-mount assembly for space-constrained boards. Consider the operating voltage limits and maximum clock frequency specifications to ensure compatibility with your system's timing constraints and power supply rails.

Counter Dividers Part Context

This part belongs to the CD4000 series of CMOS logic devices, specifically designed as a 12-stage ripple carry binary counter. It shares architectural similarities with the CD4020BC and CD4060BC but provides exactly twelve output stages. The device utilizes standard complementary metal-oxide-semiconductor technology for low power consumption.

Counter Dividers FAQ

How does the reset function operate?

The counter resets to the zero state when a logical high is applied to the reset input, functioning independently of the clock signal.

What type of clock input does the CD4040BC use?

It utilizes a Schmitt trigger clock input, which provides improved noise immunity compared to standard logic inputs.
