74VHC4040MX

Counter Dividers Overview

The onsemi 74VHC4040MX is a 12-stage binary counter fabricated with silicon gate CMOS technology. It increments on the negative edge of the clock input and resets to low via a master reset signal. The device operates within a supply voltage range of 2.0 V to 5.5 V, supporting interfaces between 5 V and 3 V systems. It features high-speed operation with a maximum frequency of 210 MHz at 5 V and low power dissipation of 4 µA max at 25°C. The component includes power-down protection on all inputs and offers high noise immunity.

Counter Dividers Feature Summary

• Advanced high-speed CMOS fabrication for Bipolar Schottky TTL-like performance
• Power-down protection provided on all inputs to prevent destruction from mismatched voltages
• Pin and function compatible with 74HC4040 standard

Counter Dividers Applications

• Interface between 5 V and 3 V systems
• Battery backup two-supply system interfacing
• General-purpose 12-stage binary counting applications

Counter Dividers Procurement Notes

Verify that the ordering suffix 'X' corresponds to tape and reel packaging as specified in the datasheet. Confirm the manufacturer origin, noting the document references Fairchild Semiconductor specifications which are now part of onsemi's portfolio. Ensure the specific lot matches the required operating temperature range of -40°C to +85°C.

Counter Dividers Selection Notes

Select this component when a 12-stage binary counter is required with high-speed capabilities up to 210 MHz. It is suitable for designs needing compatibility with 74HC4040 pinouts while benefiting from VHC series speed improvements. Consider the wide operating voltage range if the design involves mixed-voltage logic levels or battery-backed systems.

Counter Dividers Part Context

The 74VHC4040MX belongs to the VHC (Very High Speed CMOS) logic family. This series is designed to achieve high-speed operation similar to equivalent Bipolar Schottky TTL devices while maintaining the low power dissipation characteristic of CMOS technology. The 'M' suffix indicates the SOIC package, and 'X' denotes tape and reel availability.

Counter Dividers Replacement Considerations

The datasheet explicitly states pin and function compatibility with the 74HC4040. Other manufacturers producing the 74VHC4040 specification may serve as functional replacements, provided they adhere to the same electrical characteristics and package dimensions.
