74HC4040DB-Q100J

Counter Dividers Overview

The Nexperia 74HC4040DB-Q100 is a 12-stage binary ripple counter qualified to AEC-Q100 Grade 1. It features an asynchronous master reset (MR) and advances on the HIGH-to-LOW clock transition (CP). The device operates within a supply voltage range of 2.0 V to 6.0 V, with input levels compatible with CMOS standards. It includes clamp diodes for interfacing voltages exceeding VCC. The component supports ambient temperatures from -40 °C to +125 °C and provides ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Counter Dividers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1.
• Wide supply voltage range supporting 2.0 V to 6.0 V operation.
• High noise immunity with latch-up performance exceeding 100 mA per JESD 78 Class II Level B.
• Inputs include clamp diodes enabling current limiting resistors for voltages in excess of VCC.

Counter Dividers Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters

Counter Dividers Procurement Notes

Verify the specific package variant against the official datasheet revision history. The ordering suffix 'DB' indicates an SSOP-16 package which was removed from the product specification in version 2.0 and later revisions. Confirm that the supplied component matches the currently active SO16 or TSSOP16 packages listed in the latest documentation to ensure functional compliance.

Counter Dividers Selection Notes

Select this component for automotive designs requiring a 12-bit binary counter. Ensure the design utilizes the correct logic family; HC variants use CMOS input levels while HCT variants use TTL levels. Verify that the application environment remains within the specified temperature range of -40 °C to +125 °C and that power dissipation limits are respected under maximum load conditions.

Counter Dividers Part Context

This part belongs to the Nexperia 74HC_HCT4040-Q100 series, which comprises 12-stage binary ripple counters designed for automotive applications. The series is available in multiple package options including SO16, TSSOP16, and DHVQFN16. All variants share identical functional characteristics but differ in physical dimensions and thermal properties as defined by their respective package outlines.

Counter Dividers Replacement Considerations

The 74HC4040PW-Q100 serves as a direct functional replacement, offering identical electrical specifications in a TSSOP16 package. Other valid substitutes within the same family include the 74HC4040D-Q100 (SO16) and the 74HC4040BQ-Q100 (DHVQFN16), provided the mechanical footprint requirements align with the target PCB layout.
