MM74HC4040MX

Counter Dividers Overview

The MM74HC4040MX is a 12-stage binary ripple counter manufactured by onsemi, utilizing advanced silicon-gate CMOS technology. It operates within a supply voltage range of 2V to 6V and supports an operating temperature from -40°C to +85°C. The device increments on the falling edge of the input clock and resets via a logical high signal. It features a typical propagation delay of 16ns and maximum quiescent current of 80µA at 6V. The component is housed in a 16-lead Small Outline Integrated Circuit (SOIC) package.

Counter Dividers Feature Summary

• Advanced silicon-gate CMOS implementation for high-speed operation with low power dissipation
• 12-stage asynchronous binary counting capability incremented on negative clock transitions
• Integrated static discharge protection diodes on all inputs connected to VCC and ground

Counter Dividers Applications

• Digital frequency division circuits
• Binary sequence generation systems
• Timing control logic applications

Counter Dividers Procurement Notes

Verify that the specific ordering suffix 'MX' corresponds to the tape and reel packaging configuration as indicated in the datasheet notes. Confirm the manufacturer designation matches onsemi specifications, noting historical Fairchild Semiconductor origins. Ensure compliance with RoHS directives and check for any temporary certification suspensions affecting production quality standards.

Counter Dividers Selection Notes

Select this component when a 12-bit asynchronous binary counter is required within a 2V to 6V operational window. The SOIC-16 surface mount package facilitates automated assembly processes. Consider the 16ns typical propagation delay and 80µA maximum quiescent current limits for power-sensitive designs requiring CMOS noise immunity comparable to LS-TTL logic levels.

Counter Dividers Part Context

This device belongs to the MM74HC series of high-speed CMOS logic integrated circuits. It serves as a digital counter alternative to older bipolar technologies while maintaining compatibility with standard logic families. The part provides a compact solution for sequential logic operations in consumer electronics and industrial control systems requiring reliable binary counting functions.

Counter Dividers Replacement Considerations

The MM74HC4040MTC (TSSOP-16) and MM74HC4040N (PDIP-16) are pin-compatible variants offering different physical footprints. Cross-reference with other manufacturers' 74HC4040 equivalents if package constraints require alternatives outside the SOIC-16 form factor.
