CD74HCT4040MT

Counter Dividers Overview

The CD74HCT4040MT is a 12-bit asynchronous binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum counting rate of 16 MHz at nominal supply. The device utilizes negative-edge-triggered flip-flops and counts in the upward direction. It is housed in a 16-pin SOIC package with an operating temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Provides 12-bit asynchronous binary counting capability using negative-edge-triggered flip-flops.
• Supports high-speed operation with a maximum counting rate of 16 MHz under standard conditions.
• Features an asynchronous reset function for immediate clearing of the count state.

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation for digital clocks
• Event counting in industrial control systems

Counter Dividers Procurement Notes

Verify the specific suffix 'MT' against official Texas Instruments documentation to confirm package details and availability status, as datasheets may list variants like 'M' or 'MG4'. Ensure the component meets RoHS3 compliance requirements if specified for your project. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and lead times.

Counter Dividers Selection Notes

Select this component when a 12-bit asynchronous counter is required for applications needing wide counting ranges. The HCT logic family ensures compatibility with standard TTL inputs while offering CMOS power efficiency. Consider the 16 MHz speed limit and the asynchronous nature of the outputs when designing timing-critical circuits compared to synchronous alternatives.

Counter Dividers Part Context

This device belongs to the Texas Instruments CD74HCT series of high-speed CMOS logic devices. It is part of the broader 74HCT4040 family, which includes variants such as CD74HC4040 and SN74HC4040. These counters are designed for general-purpose digital applications requiring reliable binary counting functionality across a wide industrial temperature range.

Counter Dividers Replacement Considerations

CD74HCT4040M96 (Texas Instruments) is listed as a parameter-equivalent alternative. Nexperia 74HCT4040D is also noted as a similar replacement option. Verify pinout and electrical characteristics before substitution.
