CD4029BK

Counter Dividers Overview

The CD4029BK is a CMOS binary/decade counter and divider manufactured by Harris Corporation. It features a 4-bit architecture with presettable capability, supporting both up and down counting modes. The device operates on a supply voltage range of 3V to 18V and utilizes a 16-CFP (Flat Pack) surface-mount package. It includes dedicated carry/borrow outputs for cascading multiple units. The component is rated for an operating temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Supports both binary and decade counting configurations via mode selection
• Features positive edge-triggered operation for precise timing control
• Includes parallel load capability for immediate preset value assignment
• Provides cascading outputs for multi-stage expansion

Counter Dividers Applications

• Digital frequency division circuits
• Binary or decimal counting systems
• Timing and delay generation modules
• Cascaded counter arrays for larger modulus operations

Counter Dividers Procurement Notes

Verify the manufacturer designation, as Harris Corporation assets were acquired by Renesas Electronics. Confirm RoHS compliance status, as older Harris batches may not meet current environmental standards. Ensure the 16-CFP package variant matches the PCB footprint requirements. Check for lead-free soldering compatibility if required by assembly processes.

Counter Dividers Selection Notes

Select this component when a single-chip solution for up/down counting is required without external logic gates. Consider the 3V-18V operating range for flexibility in power supply design. Evaluate the 16-CFP package for surface-mount assembly needs. Verify that the presettable feature aligns with system initialization requirements.

Counter Dividers Part Context

The CD4029BK belongs to the 4000B series of CMOS logic devices, known for wide voltage operation and low power consumption. This specific part integrates counting and dividing functions into one package, reducing board space compared to discrete gate implementations. It serves as a foundational building block for digital timing and sequence control applications.

Counter Dividers Replacement Considerations

CD4029BE: Pin-compatible alternative from the same series. CD4017: Decade counter only, no binary mode. CD4040: Ripple counter, lacks preset functionality. Verify pinout and electrical characteristics before substitution.
