CD74HC4040E

Counter Dividers Overview

The CD74HC4040E is a 12-bit asynchronous binary ripple counter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features an up-counting direction with negative-edge triggering. The device utilizes a 16-pin DIP package and supports an operating temperature range from -55°C to +125°C. Key electrical specifications include a maximum frequency of 35 MHz at nominal supply, a load capacitance of 50 pF, and a maximum output current of 5.2 mA.

Counter Dividers Feature Summary

• Provides 12-stage asynchronous binary counting capability using negative-edge triggered flip-flops.
• Supports wide supply voltage operation ranging from 2 V to 6 V for flexible system integration.
• Features industrial-grade extended temperature performance suitable for harsh environments.

Counter Dividers Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters

Counter Dividers Procurement Notes

Verify the specific suffix 'E' corresponds to the 16-pin PDIP package when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier provides valid traceability documentation for the Texas Instruments manufacturer part number.

Counter Dividers Selection Notes

Select this component for applications requiring high-speed binary counting in industrial environments. Consider the 35 MHz maximum frequency limit for clock signal integrity. Verify that the 16-pin DIP form factor fits the target PCB footprint constraints compared to surface-mount alternatives.

Counter Dividers Part Context

This device belongs to the SN74HC/CD74HC series of high-speed CMOS logic products. It functions as a 12-stage binary ripple counter, distinct from decade counters like the 4017. The HC series offers compatibility with standard TTL input levels while maintaining low power consumption typical of CMOS technology.

Counter Dividers Replacement Considerations

Public confirmed substitute part numbers include SN74HC4040DT and SN74HC4040DR. These variants offer identical logical functionality but differ in packaging, utilizing SOIC formats instead of the PDIP configuration found in the CD74HC4040E.
