CD4029BCN

Counter Dividers Overview

The CD4029BCN is a CMOS presettable up/down counter manufactured by onsemi. It features a 4-bit binary or BCD counting capability with synchronous positive-edge triggering. The device supports bidirectional counting and includes asynchronous parallel data preset functionality. It operates within a supply voltage range of 3V to 18V and functions across an industrial temperature range of -55°C to 125°C. Packaged in a 16-pin PDIP, it provides carry input/output for cascading applications.

Counter Dividers Feature Summary

• Supports selectable binary or BCD counting modes via dedicated control inputs
• Enables bidirectional counting through independent up/down control logic
• Provides asynchronous parallel load capability for immediate data presetting
• Includes carry output and input terminals to facilitate multi-stage cascading

Counter Dividers Applications

• Digital timing circuits requiring precise count sequences
• Frequency division networks utilizing cascaded counter stages
• Control systems implementing programmable event counters
• Binary-coded decimal processing units in digital instrumentation

Counter Dividers Procurement Notes

Verify the specific suffix 'BCN' against the manufacturer's current datasheet to confirm package dimensions and pinout compatibility. Confirm that the operating temperature range meets your system requirements, as the 'B' variant typically indicates extended industrial specifications. Ensure that the supply voltage levels align with the specified 3V to 18V operational limits before integration into the final design.

Counter Dividers Selection Notes

Select this component when a single IC must handle both binary and decimal counting operations without external decoding logic. The synchronous positive-edge trigger ensures reliable operation in high-speed digital environments. Consider the 16-pin DIP package for prototyping or through-hole manufacturing processes where surface-mount options are not feasible for the assembly line.

Counter Dividers Part Context

This part belongs to the standard 4000B series of CMOS logic devices, known for wide voltage tolerance and low power consumption. The CD4029 specifically addresses applications needing flexible counting directions and formats. As a legacy component from onsemi, it maintains pin-out compatibility with other manufacturers' versions of the CD4029B, facilitating cross-brand sourcing strategies.

Counter Dividers Replacement Considerations

Compatible substitutes include the SN74LS192 for TTL-based designs, though voltage levels differ significantly. For direct CMOS replacements, verify equivalents such as the HEF4029B or MC14029B from other vendors. Ensure that any substitute maintains the same 16-pin DIP footprint and electrical characteristics to avoid circuit redesign.
