MC74HC4040AFR2

Counter Dividers Overview

The MC74HC4040AFR2 is a 12-stage binary ripple counter manufactured by onsemi, belonging to the 74HC logic series. It operates within a supply voltage range of 2 V to 6 V and features asynchronous active-high reset. The device utilizes negative-edge-triggered master-slave flip-flops, advancing the count state on the falling edge of the clock input. It is housed in a 16-SOEIAJ surface-mount package and supports an operating temperature range from -55°C to 125°C.

Counter Dividers Feature Summary

• Consists of twelve cascaded master-slave flip-flops for binary counting
• Features asynchronous active-high reset functionality
• Provides output drive capability compatible with ten LSTTL loads
• Outputs interface directly with CMOS, NMOS, and TTL logic families

Counter Dividers Applications

• Digital frequency division circuits
• Binary sequence generation systems
• Time-base counters in digital instrumentation

Counter Dividers Procurement Notes

Verify the specific suffix 'FR2' against the official datasheet to confirm the 16-SOEIAJ packaging and tape-and-reel configuration. Ensure the component meets RoHS compliance requirements if mandated by the design specifications. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status.

Counter Dividers Selection Notes

Select this component when a high-performance silicon-gate CMOS 12-bit counter is required. It is suitable for designs needing compatibility with standard CMOS outputs and low input current characteristics. Consider the negative-edge triggering requirement for clock synchronization and the potential for decoding spikes due to internal ripple delays in synchronous applications.

Counter Dividers Part Context

This part belongs to the MC74HC4040A family of 12-stage binary ripple counters. It shares pinout compatibility with the standard CMOS MC14040 but offers improved performance characteristics typical of the HC series. The device is designed for general-purpose digital counting applications requiring robust noise immunity and wide voltage operation.

Counter Dividers Replacement Considerations

Direct substitutes include CD74HC4040M96 and SN74HC4040DR from Texas Instruments. Verify pinout compatibility and electrical specifications before substitution.
