Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74ALS86NG4 is determined by strict equivalence across the following parameters:

• Logic function: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Electrical specifications: Supply voltage 4.5V ~ 5.5V, output current 400µA/8mA, input logic levels 0.8V/2V, propagation delay 17ns @ 5V/50pF
• Operating temperature range: 0°C ~ 70°C
• Package type: 14-DIP through-hole configuration with 0.300" (7.62mm) pitch
• Series classification: 74ALS logic family

The SN74ALS86N qualifies as a direct substitute based on identical electrical performance and package specifications. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALS86N is the qualified substitute for the SN74ALS86NG4. Both parts maintain identical electrical and mechanical specifications within the 74ALS logic family. The SN74ALS86N carries active product status, ensuring continued availability and supply chain reliability. Both parts meet ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production continuity.

Selection of the SN74ALS86N is appropriate for direct replacement in existing applications without circuit modification or re-qualification, provided the original design parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS86N directly replace the SN74ALS86NG4 without circuit changes?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Direct substitution is valid for through-hole PCB applications using the 14-DIP package.

Q: What is the difference between SN74ALS86NG4 and SN74ALS86N?

A: The primary difference is product status. The SN74ALS86NG4 is discontinued at DiGi Electronics, while the SN74ALS86N remains active. Packaging format differs (the SN74ALS86N is supplied in tube packaging), but electrical performance and pin configuration 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 are the critical parameters for XOR gate substitution?

A: Logic function (XOR with 4 channels, 2 inputs), supply voltage range (4.5V ~ 5.5V), output current ratings (400µA/8mA), input logic levels (0.8V/2V), propagation delay (17ns @ 5V, 50pF), operating temperature (0°C ~ 70°C), and package type (14-DIP through-hole) must remain constant for valid substitution.

Q: Is the 14-DIP package compatible with existing PCB designs?

A: Yes. Both parts use the 14-DIP (0.300", 7.62mm) through-hole package. PCB footprints and mounting requirements are identical.
