MC14040BDR2

Counter Dividers Overview

The MC14040BDR2G is a 12-stage binary counter manufactured by onsemi, utilizing MOS P-Channel and N-Channel enhancement mode devices in a monolithic structure. It features an input wave shaping circuit and advances the count on the negative-going edge of the clock pulse. The device operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports asynchronous reset functionality. Designed for surface-mount applications, it is available in a 16-SOIC package.

Counter Dividers Feature Summary

• Fully static operation with diode protection on all inputs
• Capable of driving two low-power TTL loads or one low-power Schottky TTL load over the rated temperature range
• Features a common reset line for controlling output states

Counter Dividers Applications

• Time delay circuits
• Counter controls
• Frequency-driving circuits

Counter Dividers Procurement Notes

Verify that the ordering suffix matches the required package type and reel specifications. Confirm RoHS compliance status and ensure the component meets AEC-Q100 qualification requirements if automotive application standards are necessary. Check datasheet for specific tape and reel orientation details before procurement.

Counter Dividers Selection Notes

Select this component when a 12-bit ripple-carry binary counter is required for digital logic applications. Ensure the design accommodates the negative-edge triggering characteristic and provides appropriate pull-up or pull-down configurations for unused inputs to maintain stable operation within the specified voltage range.

Counter Dividers Part Context

This part belongs to the MC14040B series of 12-bit binary counters from onsemi. It serves as a pin-for-pin replacement for the CD4040B, facilitating direct upgrades or cross-manufacturer sourcing without requiring PCB layout modifications. The series is designed for general-purpose counting and frequency division tasks.

Counter Dividers Replacement Considerations

The MC14040BDR2G is explicitly documented as a pin-for-pin replacement for the CD4040B. Verify compatibility with existing designs referencing the CD4040B specification.
