MC14040BD

Counter Dividers Overview

The MC14040BD is a 12-bit binary ripple counter manufactured by onsemi in a 16-pin SOIC package. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and advances the count on the negative-going edge of the clock pulse. The device features diode protection on all inputs, fully static operation, and a common reset line that forces all outputs low. It is capable of driving two Low-power TTL loads or one Low-power Schottky TTL load over the rated temperature range.

Counter Dividers Feature Summary

• Features a 12-stage ripple-carry binary counter constructed with MOS P-Channel and N-Channel enhancement mode devices.
• Includes an input wave shaping circuit and diode protection on all inputs for high static voltage guarding.
• Provides a common reset line to force all outputs low simultaneously.

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify the specific suffix 'D' confirms the SOIC-16 package configuration. Confirm RoHS compliance status as standard packages may vary; Pb-free options are available under different ordering suffixes. Check current lifecycle status as components may be subject to discontinuation or limited availability updates from the manufacturer.

Counter Dividers Selection Notes

Select this component when a 12-bit asynchronous binary counter is required. Ensure the design accommodates negative-edge clock triggering. Verify that the application logic can handle the propagation delays associated with ripple counters rather than synchronous architectures. Confirm power supply stability within the 3V to 18V range.

Counter Dividers Part Context

This part belongs to the MC14040B series of 12-bit binary counters. It serves as a pin-for-pin replacement for the CD4040B. The device is part of the broader 4000/14000/40000 series of CMOS logic integrated circuits designed for general-purpose digital applications requiring binary counting functions.

Counter Dividers FAQ

How does the MC14040BD advance its count?

The device advances the count on the negative-going edge of the clock pulse.

What is the function of the Reset input?

When the Reset input is high, all outputs are forced low regardless of the clock state.
