74HCT4040DB-Q100J

Counter Dividers Overview

The Nexperia 74HCT4040DB-Q100J is a 12-stage binary ripple counter designed for automotive applications, qualified to AEC-Q100 Grade 1. 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.

Counter Dividers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• Wide operating temperature range specified from -40 °C to +125 °C
• CMOS low power dissipation with high noise immunity
• Latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Counter Dividers Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters

Counter Dividers Procurement Notes

Verify current production status directly with Nexperia or authorized distributors, as automotive logic components may undergo lifecycle changes. Confirm package availability matches the SO16 (SOT109-1) specification required for your design. Ensure compliance with RoHS directives and REACH regulations before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a 12-bit binary counting function is required in automotive environments. The HCT series ensures compatibility with standard TTL logic levels at 5 V operation. Verify that the system's maximum frequency requirements fall within the specified dynamic characteristics for the chosen supply voltage and load conditions.

Counter Dividers Part Context

This part belongs to the Nexperia 74HCT4040-Q100 family of 12-stage binary ripple counters. It shares functional similarities with other automotive-grade logic ICs but is distinct in its specific count stages and interface requirements. The 'DB' designation indicates the SO16 plastic small outline package variant.

Counter Dividers Replacement Considerations

Direct substitutes include the 74HC4040D-Q100J for HC-level input compatibility or the 74HCT4040PW-Q100J for alternative TSSOP packaging. Verify pinout consistency and electrical specifications against the original datasheet before substitution.
