MC74HC4040AD

Counter Dividers Overview

The MC74HC4040AD is a 12-stage binary ripple counter manufactured by onsemi using high-performance silicon-gate CMOS technology. It operates within a DC supply voltage range of 2.0 to 6.0 V and features an asynchronous active-high reset input. The device consists of 12 master-slave flip-flops where each output frequency is half that of the preceding stage, advancing on the negative-going edge of the clock input. It provides an output drive capability of 10 LSTTL loads and interfaces directly with CMOS, NMOS, and TTL logic families.

Counter Dividers Feature Summary

• Consists of 12 master-slave flip-flops for binary counting
• Features asynchronous active-high reset functionality
• Provides direct interface compatibility with CMOS, NMOS, and TTL outputs
• Delivers output drive capability equivalent to 10 LSTTL loads

Counter Dividers Applications

• Time-base generator circuits
• Frequency division applications
• Binary counting sequences

Counter Dividers Procurement Notes

Verify the specific package suffix against official documentation, as ordering codes determine physical form factors such as SOIC-16 or TSSOP-16. Confirm availability status through authorized channels, noting that certain variants may be discontinued. Ensure compliance with RoHS and lead-free requirements if specified in the final purchase order.

Counter Dividers Selection Notes

Select this component when a 12-bit binary ripple counter is required for digital timing or sequencing tasks. Consider the internal ripple delay characteristics which cause non-simultaneous state changes at Q outputs; gated decoding may be necessary for designs sensitive to decoding spikes. Verify operating temperature ranges and supply voltage constraints match the target application environment.

Counter Dividers Part Context

This device belongs to the 74HC series of high-speed CMOS logic integrated circuits. It shares pinout compatibility with standard CMOS devices like the MC14040 but offers improved switching speeds and lower power consumption typical of the HC family. The component is designed for general-purpose digital logic applications requiring reliable binary counting capabilities.

Counter Dividers Replacement Considerations

Direct substitutes include other 12-stage binary counters from compatible logic families. Verify pinout compatibility and electrical specifications before substitution. Check manufacturer discontinuation notices for alternative sourcing options.
