Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74ALS08NSRG4 is determined by the following critical parameters:

• Logic Type: AND Gate with 4 channels and 2 inputs per channel
• Electrical Specifications: 4.5V ~ 5.5V supply voltage, 14ns maximum propagation delay, matching input/output current ratings
• Package Compatibility: 14-SOIC surface mount package with identical pin configuration
• Environmental Compliance: ROHS3 compliance and MSL Level 1 rating

The SN74ALS08NSR meets all these criteria and is qualified as a direct substitute. The primary difference is packaging format (Tape & Reel versus individual packaging) and product status (Active versus Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The SN74ALS08NSR is the qualified substitute for the SN74ALS08NSRG4. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The SN74ALS08NSR maintains active product status, ensuring continued availability and supply chain reliability. Both parts meet ROHS3 compliance requirements and carry MSL Level 1 moisture sensitivity ratings, suitable for standard storage and handling conditions.

The primary consideration for selection is packaging format. The SN74ALS08NSR is supplied in Tape & Reel format, which is standard for high-volume production environments. If individual packaging is required, alternative sourcing or packaging services may be necessary.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS08NSR directly replace the SN74ALS08NSRG4 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. Pin configuration, electrical performance, and operating characteristics are equivalent. No circuit modifications are required.

Q: What is the difference between the two part numbers?
