MC74AC4040MEL

Counter Dividers Overview

The MC74AC4040MEL is a 12-bit binary counter manufactured by onsemi, belonging to the 74AC logic series. It features asynchronous reset and negative-edge triggered flip-flops for upward counting operations. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum counting rate of 140 MHz. Designed for surface-mount applications, it utilizes a 16-SOEIAJ package with dimensions of 5.30 mm width. The component functions reliably across an extended industrial temperature range from -40°C to +85°C.

Counter Dividers Feature Summary

• High-speed 12-bit binary counting capability with negative-edge triggering
• Asynchronous reset function for immediate state initialization
• Wide operating voltage range supporting low-power system integration

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation in timing systems
• Address counter stages in memory addressing architectures

Counter Dividers Procurement Notes

Verify the specific suffix MEL against official documentation to confirm the 16-SOEIAJ surface-mount package configuration. Confirm that the asynchronous reset functionality aligns with system requirements. Ensure compatibility with the specified 2 V to 6 V supply range and check for any RoHS compliance updates prior to procurement.

Counter Dividers Selection Notes

Select this component when a high-speed 12-bit binary counter is required in a compact surface-mount form factor. The 74AC series offers superior speed compared to standard 74LS counterparts while maintaining CMOS power efficiency. Verify that the 16-SOEIAJ footprint fits the PCB layout constraints and that the operating voltage matches the target system rails.

Counter Dividers Part Context

This part belongs to the industry-standard 74AC family of logic integrated circuits. The 74AC4040 serves as a fundamental building block for sequential logic designs requiring multi-stage binary accumulation. It provides a reliable solution for digital systems needing precise clock division or event counting capabilities within automotive and industrial environments.

Counter Dividers Replacement Considerations

Consult manufacturer documentation for direct pin-compatible alternatives within the 74AC or 74ACT families. Verify electrical characteristics such as propagation delay and supply current when substituting with other manufacturers' equivalents.
