MC74HC4040ADR2

Counter Dividers Overview

The MC74HC4040ADR2G 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 supports a maximum clock frequency of 50 MHz at 6.0 V. The device features an asynchronous active-high reset input that forces all outputs low, while state changes advance on the negative-going edge of the clock signal. Packaged in a 16-lead SOIC surface-mount format, it provides 12 active-high outputs (Q1 through Q12) where each stage divides the preceding frequency by two.

Counter Dividers Feature Summary

• Consists of 12 master-slave flip-flops with asynchronous active-high reset functionality
• Outputs directly interface to CMOS, NMOS, and TTL logic families
• State advances on the negative-going edge of the clock input
• Compliant with JEDEC standard requirements for noise immunity

Counter Dividers Applications

• Time-base generator circuits
• Frequency division applications
• Digital counting systems

Counter Dividers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and environmental compliance. Confirm RoHS status and Pb-free designation as required by project specifications. Ensure the selected variant matches the intended operating temperature range and voltage requirements before procurement.

Counter Dividers Selection Notes

Select this component when a 12-bit binary counter with asynchronous reset is required. Verify compatibility with system voltage levels between 2.0 V and 6.0 V. Consider the ripple delay characteristics for timing-sensitive designs, as decoded output signals may require gating with the clock signal to prevent decoding spikes.

Counter Dividers Part Context

This device belongs to the 74HC series of high-speed CMOS logic components. It shares pinout compatibility with standard CMOS devices like the MC14040 but offers improved switching speeds and lower power consumption typical of HC technology. The product line includes variants for automotive applications requiring AEC-Q100 qualification.
