4024BDMQB

Overview

The 4024BDMQB is a 7-stage ripple carry binary counter manufactured by National Semiconductor. It operates within the 4000/14000/40000 series and utilizes CMOS technology. The device features negative edge triggering for synchronous operation in an up-counting direction. It supports a maximum count rate of 30 MHz and is housed in a 16-CDIP package with dimensions of 0.300 inches (7.62 mm).

Feature Summary

• Seven-stage ripple carry binary counting capability
• Negative edge triggered synchronous operation
• CMOS construction for low power consumption

Applications

• Digital frequency division circuits
• Binary counting applications
• Timing sequence generation systems

Procurement Notes

Verify the manufacturer designation, as National Semiconductor assets are managed by Texas Instruments. Confirm the specific suffix 'DMQB' corresponds to the required 16-CDIP package and commercial temperature range. Ensure compatibility with existing board layouts requiring through-hole mounting.

Selection Notes

Select this component when a 7-bit synchronous binary counter is required. The negative edge trigger characteristic must align with the system clock polarity. Verify that the 30 MHz maximum count rate meets the application's speed requirements and that the CDIP package fits the available footprint.

Part Context

This part belongs to the standard 4000-series CMOS logic family. It serves as a fundamental building block for digital electronics, providing reliable binary counting functions. The device is widely used in educational kits and industrial control systems where robust, low-power counting is necessary.

Replacement Considerations

The CD4024 is the primary equivalent part number. Verify pinout compatibility and electrical specifications before substitution.
