CD4029BM

Counter Dividers Overview

The CD4029BM is a CMOS synchronous up/down counter and divider from the Texas Instruments 4000B series. It features a 4-bit binary or BCD counting capability with selectable up or down operation via an external control input. The device includes asynchronous reset, ripple clock inputs for cascading, and independent carry outputs for both binary and BCD modes. It operates on a single power supply ranging from 3V to 18V and is housed in a 16-pin SOIC package.

Counter Dividers Feature Summary

• Synchronous up/down counting functionality with selectable binary or BCD modulus
• Asynchronous reset input for immediate clearing of all flip-flops
• Independent carry outputs for both binary and BCD counting modes
• Ripple clock inputs enabling easy cascading of multiple counters

Counter Dividers Applications

• Digital frequency division circuits
• Time base generation for clocks and timers
• Cascaded counter systems for extended range counting
• Event counting applications requiring up/down direction control

Counter Dividers Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm package type and temperature grade. Ensure the ordering code matches the required tape-and-reel or tube packaging format. Confirm RoHS compliance status if restricted substances are mandated by the end product specifications.

Counter Dividers Selection Notes

Select this component when synchronous counting with explicit up/down control is required. It is suitable for designs needing separate carry signals for different counting moduli. Consider the operating voltage range and package availability relative to the PCB layout constraints.

Counter Dividers Part Context

This part belongs to the standard 4000B CMOS logic family, known for wide voltage operation and high noise immunity. It serves as a fundamental building block for digital timing and sequencing logic within industrial and consumer electronic systems.

Counter Dividers Replacement Considerations

Check for CD4029BMT (tape and reel variant) or CD4029BE (tube variant) for identical electrical performance with different packaging. Verify pinout compatibility before substituting.
