MC14029BFELG

Counter Dividers Overview

The MC14029BFELG is a Binary/Decade Up/Down Counter manufactured by onsemi, utilizing complementary MOS P-channel and N-channel enhancement mode devices in a single monolithic structure. It features type D flip-flop stages with gating for toggle capability, supporting both Binary and BCD operation modes. The device operates within a supply voltage range of 3.0 Vdc to 18 Vdc and functions across an ambient temperature range of -55°C to +125°C. Packaged in SOIC-16 (CASE 751B), it provides pin-for-pin replacement for CD4029B equivalents.

Counter Dividers Feature Summary

• Diode protection integrated on all inputs
• Internally synchronous logic design for high-speed performance
• Asynchronous preset enable operation capability
• Capable of driving two Low-Power TTL loads or one Low-Power Schottky TTL load

Counter Dividers Applications

• Up/down counting applications
• Difference counting circuits
• Frequency synthesizer systems
• A/D and D/A conversion modules
• Magnitude and sign generation

Counter Dividers Procurement Notes

Verify the specific suffix 'FELG' against official ordering lists, as standard datasheets list 'D' (SOIC-16) and 'DR2G' (Tape & Reel). Confirm RoHS compliance and Pb-Free status. Ensure automotive requirements are met if using NLV prefix variants. Validate package dimensions and marking diagrams for the exact revision.

Counter Dividers Selection Notes

Select this component for designs requiring low power dissipation and high noise immunity. It supports both binary and BCD modes via external control. Verify clock pulse width and frequency limits against system timing requirements. Ensure unused inputs are tied to appropriate logic levels to prevent undefined states.

Counter Dividers Part Context

Part of the MC14000 series CMOS logic family, designed for general-purpose digital counting tasks. It serves as a direct replacement for industry-standard CD4029B devices. The technology leverages complementary MOS structures to achieve robust performance in industrial and commercial environments.

Counter Dividers Replacement Considerations

Pin-for-pin compatible with CD4029B. For automotive applications requiring unique site and control changes, consider the NLV14029BDR2G variant which is AEC-Q100 qualified and PPAP capable.
