CD4029BD3

Counter Dividers Overview

The CD4029BD3 is a synchronous, positive edge-triggered 4-bit bidirectional binary counter from the Harris Corporation 4000/14000/40000 series. It features CMOS technology and operates within a supply voltage range of 3 V to 18 V, with a nominal rating of 5 V. The device supports both binary and BCD counting modes via an external input. Key functional inputs include count enable and load/preset capabilities. It provides a terminal count output (TCO) for cascading applications. The component is housed in a 16-lead ceramic dual in-line package (CDIP16) designed for high-temperature environments.

Counter Dividers Feature Summary

• Supports bidirectional counting operations with selectable binary or BCD modes
• Includes dedicated count enable and load/preset control inputs
• Features a terminal count output signal for multi-stage expansion

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation systems
• Cascaded digital counting modules

Counter Dividers Procurement Notes

Verify the manufacturer designation on the component marking, as production may have transitioned from Harris Corporation to Intersil or Renesas. Confirm that the specific order suffix corresponds to the ceramic DIP16 package variant. Ensure compliance with required environmental specifications, as this part is rated for extended temperature ranges suitable for industrial or military contexts.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with flexible counting direction is required. It is appropriate for designs needing simultaneous binary and BCD operation without additional decoding logic. Consider the CDIP16 package constraints if board space allows for through-hole mounting in high-reliability applications requiring wide voltage tolerance.

Counter Dividers Part Context

This device belongs to the standard 4000-series CMOS logic family, known for broad supply voltage compatibility and low static power consumption. The CD4029 variant specifically addresses applications requiring compact, synchronous counting solutions. Its integration of mode selection and enable controls reduces the need for external gating components compared to asynchronous alternatives.

Counter Dividers Replacement Considerations

Cross-reference with other 4000-series compatible parts such as the CD4029BFMSH or generic equivalents from manufacturers like Texas Instruments or ON Semiconductor. Verify pinout compatibility and ensure the replacement supports the same bidirectional and BCD/binary switching functionality.
