Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74ALS32NG4 is determined by strict equivalence across the following critical parameters:

• Logic type and circuit configuration (4-channel OR gate with 2 inputs per channel)
• Electrical specifications (4.5V ~ 5.5V supply voltage, 14ns propagation delay, input/output current ratings)
• Physical package format (14-DIP through-hole mounting)
• Regulatory compliance (ROHS3 and REACH status)

The SN74ALS32N qualifies as a direct substitute based on identical electrical and functional parameters. The primary distinction is product status and packaging format, with SN74ALS32N currently active in inventory.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALS32N is the direct equivalent for the discontinued SN74ALS32NG4. Both parts maintain identical electrical performance, operating parameters, and regulatory compliance certifications. The SN74ALS32N is currently active in production with 3700 units in stock, providing reliable procurement availability. Selection of SN74ALS32N eliminates obsolescence risk while preserving full functional and electrical compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS32N replace SN74ALS32NG4 in existing designs?

A: Yes. Both parts are electrically and functionally identical across all specified parameters, including supply voltage, propagation delay, input/output current ratings, and operating temperature range. The 14-DIP through-hole package is identical, enabling direct board-level substitution.

Q: What is the difference between SN74ALS32NG4 and SN74ALS32N?

A: The primary difference is product status. SN74ALS32NG4 is discontinued at DiGi Electronics, while SN74ALS32N remains active in production. Both use identical packaging formats and electrical specifications.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting the same regulatory requirements for industrial and commercial applications.

Q: What packaging formats are available for the 74ALS32 series?

A: Both the main part and substitute are supplied in tube packaging format with 14-DIP through-hole mounting.

Q: Is the 14-DIP package compatible with standard breadboards and PCB footprints?

A: Yes. The 14-DIP (0.300", 7.62mm) package is a standard through-hole format compatible with conventional 0.1-inch pitch breadboards and PCB designs.
