SN74HC4040ANS

Counter Dividers Overview

The SN74HC4040ANS is a 12-bit asynchronous binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports counting rates up to 33 MHz. The device features negative-edge triggering, asynchronous reset, and upward counting direction. It is housed in a 16-pin SOIC package with an operating temperature range of -40°C to 85°C.

Counter Dividers Feature Summary

• Provides 12-bit asynchronous binary counting capability
• Features negative-edge triggered clock inputs
• Includes asynchronous reset functionality for immediate state clearing

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation systems
• Event counting applications

Counter Dividers Procurement Notes

Verify the specific suffix 'ANS' against official Texas Instruments documentation to confirm pinout compatibility and electrical characteristics. Ensure the component matches the required 16-SOIC package dimensions and lead finish specifications before integration into production designs.

Counter Dividers Selection Notes

Select this component when a high-speed, 12-bit asynchronous counter is required. It is suitable for designs needing simple upward counting with minimal control logic overhead. Consider the 33 MHz maximum frequency and 2-6 V supply range to ensure compatibility with the target system's power and speed requirements.

Counter Dividers Part Context

This part belongs to the SN74HC series of high-speed CMOS logic devices. It is functionally similar to other 12-bit counters like the CD74HC4040 but offers improved switching speeds and lower power consumption typical of the HC family. It serves as a fundamental building block for sequential logic design.

Counter Dividers Replacement Considerations

Compatible substitutes include SN74HC4040D and SN74HC4040DR from Texas Instruments. Verify that alternative packages maintain the same 16-pin SOIC footprint and electrical parameters.
