SN74HC4040NG4 Equivalent & Substitute Parts

Part Overview

The SN74HC4040NG4 is a 12-bit binary counter IC manufactured by Texas Instruments, designed for digital counting applications requiring negative edge triggering. This component operates across a wide supply voltage range of 2V to 6V and supports count rates up to 33 MHz with asynchronous reset and timing characteristics.

The SN74HC4040NG4 is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. The primary substitute maintains identical electrical and mechanical specifications while offering improved availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74HC4040NG4 is determined by strict equivalence across the following critical parameters:

• Logic Function: Binary counter with identical 12-bit architecture and up-counting direction
• Electrical Characteristics: Matching 33 MHz count rate, negative edge trigger type, and 2V to 6V supply voltage range
• Thermal Performance: Identical -40°C to 85°C operating temperature range
• Mechanical Compatibility: 16-DIP package with 0.300" (7.62mm) pitch for through-hole mounting
• Reset Behavior: Asynchronous reset functionality

The SN74HC4040N substitute meets all these criteria while differing only in packaging format (tube vs. unspecified) and product status (active vs. discontinued).

Parameter Comparison

Engineering Selection Recommendations

The SN74HC4040N is the direct equivalent substitute for the SN74HC4040NG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, mechanical dimensions, and compliance certifications (ROHS3 Compliant, REACH Unaffected).

The primary distinction is product status: the SN74HC4040NG4 is discontinued, while the SN74HC4040N maintains active status with significantly higher inventory availability (2400 pieces vs. 747 pieces). For new designs and ongoing production, the SN74HC4040N is the appropriate selection.

Both parts meet the same regulatory requirements and are suitable for applications requiring 12-bit binary counting at up to 33 MHz across the 2V to 6V supply range.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC4040N directly replace the SN74HC4040NG4 in existing designs?

A: Yes. The SN74HC4040N is electrically and mechanically identical to the SN74HC4040NG4. Both use the 16-DIP through-hole package with identical pin configurations, electrical characteristics, and operating ranges. No circuit modifications are required.

Q: What is the difference between SN74HC4040NG4 and SN74HC4040N?

A: The parts differ only in packaging format and product status. The SN74HC4040NG4 is discontinued, while the SN74HC4040N is active. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance and REACH Unaffected status. They meet the same regulatory requirements for industrial and commercial applications.

Q: What is the 16-DIP package specification?

A: The 16-DIP package is a through-hole dual inline package with 16 pins spaced 0.300 inches (7.62mm) apart. This standard package is compatible with conventional PCB through-hole mounting and breadboard applications.

Q: Can these parts be used interchangeably in production?

A: Yes. The SN74HC4040N should be used for new production due to its active status and superior availability. Existing inventory of the SN74HC4040NG4 can be used until depleted, as the parts are fully interchangeable.
