74HCT4040D-Q100J

Counter Dividers Overview

The 74HCT4040D-Q100J is a 12-stage binary ripple counter from the Nexperia 74HCT series, designed for automotive applications. It features an asynchronous master reset (MR) input and twelve parallel outputs (Q0 to Q11). The device advances on the HIGH-to-LOW transition of the clock input (CP). It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The component utilizes CMOS technology with TTL-compatible input levels and includes clamp diodes on inputs.

Counter Dividers Feature Summary

• Qualified to AEC-Q100 Grade 1 standards for automotive use
• Features an overriding asynchronous master reset function
• Provides high noise immunity and low power dissipation
• Includes ESD protection exceeding specified JEDEC class limits

Counter Dividers Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters

Counter Dividers Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple options. Confirm the temperature grade aligns with system requirements. Ensure design compliance with AEC-Q100 standards if used in automotive contexts. Check for any recent datasheet revisions that may affect pinning or electrical characteristics before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a 12-bit binary counting solution is required for automotive environments. It is suitable for designs needing TTL-level input compatibility with CMOS output drive capabilities. Consider the SO16 package constraints regarding thermal derating and physical footprint. Verify that the maximum frequency specifications meet the timing requirements of the target application circuit.

Counter Dividers Part Context

This device belongs to the Nexperia 74HCT4040-Q100 family, which includes variants in different packages such as TSSOP16 and DHVQFN16. The 'D' suffix specifically denotes the SO16 plastic small outline package. The '-Q100J' suffix indicates automotive qualification and specific packaging configuration. It is part of the broader 74HC/HCT logic family known for wide supply voltage ranges.

Counter Dividers Replacement Considerations

The 74HC4040D-Q100J serves as a non-TTL compatible alternative within the same package and qualification level. Automotive-grade equivalents like the 74HCT4040PW-Q100J offer identical functionality in a TSSOP16 package.
