MM74HC4040M

Counter Dividers Overview

The MM74HC4040M is a 12-stage binary ripple carry counter implemented with advanced silicon-gate CMOS technology. It increments on the falling edge of the input clock and resets to low via a high-level reset input. The device operates within a supply voltage range of 2V to 6V, supporting a maximum operating frequency of 50 MHz at 6V. It features low input current (1 µA max) and quiescent current (80 µA max), providing drive capability for 10 LS-TTL loads.

Counter Dividers Feature Summary

• Advanced silicon-gate CMOS implementation for high-speed performance comparable to LS-TTL logic.
• Asynchronous 12-stage binary counting with negative edge triggering and asynchronous reset functionality.
• Wide operating voltage range from 2V to 6V with protection diodes against static discharge.

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting applications in digital systems
• Timing and sequencing control modules

Counter Dividers Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete or subject to lifecycle changes. Confirm package type M16A (SOIC-16) matches design requirements. Review datasheet specifications for absolute maximum ratings and recommended operating conditions before integration to ensure compliance with system electrical constraints.

Counter Dividers Selection Notes

Select this component for designs requiring a 12-bit binary counter with CMOS compatibility. Ensure the application supports the specified 2V to 6V supply range. Consider the propagation delay characteristics when designing for high-frequency signals, as ripple counters introduce cumulative delays across stages compared to synchronous alternatives.

Counter Dividers Part Context

This component belongs to the MM74HC series of high-speed CMOS logic devices manufactured by Fairchild Semiconductor, now part of onsemi. It serves as a 12-stage counterpart to the 14-stage MM74HC4020. The device maintains pin compatibility with legacy CD4040 designs while offering improved speed and lower power consumption typical of HC technology.

Counter Dividers Replacement Considerations

Direct substitutes include the MM74HC4040N (PDIP) and MM74HC4040SJ (SOP). Verify package dimensions and lead configurations when replacing surface mount variants with through-hole options or vice versa to ensure mechanical fit.
