Substitute Part Grouping Explanation

Substitution of the SN74S09NG4 is determined by the following critical parameters:

• Logic function: 4-channel AND gate with 2 inputs per channel
• Output configuration: Open collector topology
• Electrical specifications: 4.75V to 5.25V supply voltage, 20mA output current, 9ns propagation delay at 5V with 50pF load
• Package format: 14-pin DIP with 0.300" (7.62mm) pitch
• Temperature range: 0°C to 70°C operation
• Compliance: ROHS3 compliant, REACH unaffected

The SN74S09N qualifies as a direct substitute based on identical logic function, electrical performance, package configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can the SN74S09N directly replace the SN74S09NG4 in existing designs?

A: Yes. The SN74S09N is a direct functional and electrical equivalent. Both parts feature identical logic function (4-channel AND gate), electrical performance (4.75V to 5.25V supply, 20mA output current, 9ns propagation delay), and 14-pin DIP package configuration. Pin-for-pin compatibility is maintained.

Q: What is the difference between the SN74S09NG4 and SN74S09N?

A: The primary difference is product status. The SN74S09NG4 is discontinued, while the SN74S09N remains in active production. The packaging designation differs (NG4 versus N), but electrical specifications and functional performance are identical.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance differences exist between the two parts.

Q: What packaging options are available for the SN74S09N?

A: The SN74S09N is supplied in tube packaging. The SN74S09NG4 packaging designation is not specified in available data. Both use the standard 14-DIP (0.300", 7.62mm) package format suitable for through-hole mounting.

Q: Is the open collector output configuration the same in both parts?

A: Yes. Both the SN74S09NG4 and SN74S09N feature open collector output configuration with 20mA output current capability, maintaining identical electrical behavior in circuit applications.
