Overview
The CD4024BDC is a CMOS logic device belonging to the 4000/14000/40000 series, manufactured by National Semiconductor. It functions as an asynchronous negative edge-triggered 7-bit up binary counter. The component utilizes a plastic DIP-14 package with through-hole terminals and operates within a supply voltage range of 3.0 Vdc to 18 Vdc. It features diode protection on all inputs and increased noise immunity at the clock input due to hysteresis.
Feature Summary
- Asynchronous negative edge-triggered 7-bit ripple counter architecture
- Diode protection integrated on all input terminals
- Clock input enhanced with hysteresis for improved noise immunity
- Buffered outputs capable of driving low-power TTL loads
Applications
- Digital counting circuits requiring asynchronous operation
- Frequency division applications in digital systems
- Timing and sequencing control modules
- General-purpose binary counting tasks
Procurement Notes
Verify the specific suffix 'D' against official datasheets to confirm package type and temperature rating. Ensure compatibility with the 4000-series logic family requirements. Confirm that the manufacturer designation aligns with current National Semiconductor or Texas Instruments documentation standards before finalizing procurement specifications.
Selection Notes
Select this component when a 7-stage asynchronous counter is required within the 4000-series logic family. It serves as a pin-for-pin replacement for compatible devices like the CD4024B. Consider its operating voltage range and noise immunity characteristics for environments requiring stable asynchronous counting without complex synchronization.
Part Context
This part belongs to the extensive 4000/14000/40000 series of CMOS logic devices originally developed by National Semiconductor. These components are widely recognized for their versatility in digital electronics. The 4024B variant specifically addresses the need for multi-stage binary counting in standard industrial and commercial applications.
Replacement Considerations
The MC14024B is documented as a pin-for-pin replacement option. Verify electrical parameters and package dimensions against the original specification sheet to ensure functional equivalence in the target circuit design.
