CD4029BMT

Counter Dividers Overview

The CD4029BMT is a CMOS presettable up/down counter manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and supports a counting rate of 11 MHz. The device features four bits, synchronous positive-edge triggering, and asynchronous reset functionality. It is housed in a 16-SOIC surface-mount package with dimensions of 0.154 inches (3.90 mm) width. The component functions as both a binary and decimal counter and operates across an extended temperature range from -55°C to 125°C.

Counter Dividers Feature Summary

• Supports configurable binary or decimal counting modes via external control inputs.
• Features synchronous positive-edge triggered flip-flops for precise timing synchronization.
• Includes an asynchronous reset input for immediate initialization of the count state.

Counter Dividers Applications

• Digital frequency division circuits
• Presettable time-base generators
• Up/Down counting logic modules

Counter Dividers Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm compliance with RoHS standards and lead-free requirements. Confirm that the 16-SOIC package matches the design footprint. Ensure the operating temperature range meets the environmental specifications of the target application before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a compact, low-voltage CMOS solution is required for synchronous counting applications. The wide supply voltage range allows flexibility in power system design. Verify that the 11 MHz maximum counting rate satisfies the speed requirements of the digital system architecture.

Counter Dividers Part Context

This part belongs to the Texas Instruments 4000B series of CMOS logic devices. It serves as a specialized counter within the broader family of encoders, decoders, and multiplexers. The device provides a robust alternative to older bipolar logic families, offering lower power consumption while maintaining compatibility with standard digital interfaces.

Counter Dividers Replacement Considerations

Publicly confirmed substitute part numbers include CD4029BMTE4 and CD4029BMTG4. These variants maintain functional equivalence but may differ in packaging suffixes or manufacturing lot specifications. Verify pinout compatibility before substitution.
