Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74AS1008ADRG4 is determined by strict equivalence across the following parameters:

• Logic type and circuit configuration (4-channel AND gate with 2 inputs per channel)
• Electrical specifications (supply voltage, output current, input logic levels, propagation delay)
• Package type and physical dimensions (14-SOIC surface mount)
• Compliance certifications (RoHS3, REACH status)
• Moisture sensitivity rating

The SN74AS1008AD meets all these criteria and is classified as an active product, making it a direct functional and electrical equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The SN74AS1008AD is the direct equivalent for the obsolete SN74AS1008ADRG4. Both parts share identical electrical characteristics, package specifications, and compliance certifications. The primary distinction is product status: SN74AS1008AD is actively manufactured and supported by Texas Instruments, ensuring long-term availability and supply chain continuity. For new designs or component replacement in existing applications, SN74AS1008AD is the appropriate selection. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can SN74AS1008AD be used as a direct replacement for SN74AS1008ADRG4?

A: Yes. Both parts are electrically and functionally identical across all specified parameters, including logic configuration, voltage ratings, output current, propagation delay, and package type. The primary difference is product status and packaging format.

Q: What is the difference between the packaging designations?

A: SN74AS1008ADRG4 uses a reel package format, while SN74AS1008AD uses tube packaging. Both contain the same die and are housed in 14-SOIC surface mount packages with identical physical dimensions and pin configurations.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity ratings. They are suitable for the same regulatory environments and applications.

Q: Why is SN74AS1008ADRG4 classified as obsolete?

A: Product obsolescence reflects Texas Instruments' manufacturing and support decisions. The active equivalent SN74AS1008AD provides continued access to this logic gate configuration with full manufacturer support.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process accommodates the packaging format. Both parts use identical 14-SOIC surface mount packages with the same pin pitch and footprint requirements.
