MC14040BDG

Counter Dividers Overview

The MC14040BDG is a 12-stage binary counter manufactured by onsemi using CMOS technology. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and features asynchronous reset functionality. The device advances the count on the negative-going edge of the clock pulse, providing outputs from Q1 through Q12. It is housed in a 16-pin SOIC package and supports an ambient operating temperature range from -55 °C to +125 °C.

Counter Dividers Feature Summary

• Features fully static operation with diode protection on all inputs for enhanced reliability.
• Includes a common reset line that forces all outputs low when activated.
• Capable of driving two low-power TTL loads or one low-power Schottky TTL load across the rated temperature range.

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'DG' confirms the SOIC-16 package and lead-free status as documented. Ensure the application environment remains within the specified -55 °C to +125 °C operating temperature limits. Confirm that input voltages do not exceed the maximum DC supply voltage rating of 18.0 V to prevent damage to the high-impedance circuitry.

Counter Dividers Selection Notes

Select this component for designs requiring a 12-bit ripple-carry binary counter with a wide supply voltage capability. It serves as a pin-for-pin replacement for the CD4040B, facilitating direct upgrades or cross-manufacturer sourcing. Consider the negative-edge clock triggering requirement when designing the interface logic.

Counter Dividers Part Context

This part belongs to the MC14040B series of 12-stage binary counters. It utilizes MOS P-Channel and N-Channel enhancement mode devices in a single monolithic structure. The series includes variants such as the tape-and-reel MC14040BDR2G and automotive-qualified NLV14040BDR2G options.

Counter Dividers Replacement Considerations

The datasheet explicitly identifies the CD4040B as a pin-for-pin replacement equivalent. No other substitute part numbers are confirmed in the provided documentation.

Counter Dividers FAQ

How does the MC14040B handle the counting process?

The device advances the count on the negative-going edge of the clock pulse using its 12 stages of ripple-carry binary counter.

What happens to the outputs when the reset line is active?

When the reset line is at a logic high level (X 1), all outputs are forced low regardless of the clock state.
