Counter Dividers datasheet and documents for MC74AC4040N
Counter Dividers Overview
The MC74AC4040N is a 12-stage binary ripple counter manufactured by onsemi. It consists of 12 master-slave flip-flops where each output frequency is half that of the preceding stage. The state advances on the negative-going edge of the clock input, and it features an asynchronous active-high reset. Operating within a voltage range of 2.0 to 6.0 V, it supports a typical maximum clock frequency of 140 MHz at 5.0 V. The device provides high noise immunity and outputs capable of sourcing or sinking 24 mA.
Counter Dividers Feature Summary
- Comprises 12 master-slave flip-flops for binary counting
- Features asynchronous active-high reset functionality
- Provides high noise immunity for reliable operation
- Outputs support 24 mA source/sink current
Counter Dividers Applications
- Digital binary counting circuits
- Frequency division networks
- Sequential logic systems
Counter Dividers Procurement Notes
Verify the specific package suffix against the datasheet ordering information to ensure correct physical dimensions and shipping quantities. Confirm RoHS compliance status if required by assembly specifications. Check for obsolete status as distributors may only offer limited stock from secondary sources.
Counter Dividers Selection Notes
Select this component when a 12-bit binary counter with a wide supply voltage range is needed. Ensure the application can accommodate ripple delays between stages. Verify that the load requirements do not exceed the 24 mA output drive capability. Consider the PDIP-16 package availability for through-hole mounting.
Counter Dividers Part Context
This part belongs to the 74AC logic family, utilizing CMOS technology. It serves as a fundamental building block for sequential digital circuits. The device is designed for general-purpose applications requiring stable binary counting and frequency division within standard industrial temperature ranges.

Counter Dividers FAQ
How does the reset function operate?
The reset is asynchronous and active-high. When the reset pin is high, all outputs are forced low regardless of the clock state.
What causes decoding spikes in the output?
State changes of the Q outputs do not occur simultaneously due to internal ripple delays between the cascaded flip-flops.
