Substitute Part Grouping Explanation

Substitution for the SN74ALS05ADRG4 is based on strict electrical and mechanical parameter matching within the 74ALS logic family. The following criteria determine valid substitutes:

Electrical Parameters (Must Match):

• Logic Type: Inverter
• Number of Circuits: 6
• Number of Inputs: 1
• Features: Open Collector
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Output Low: 8mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay: 54ns @ 5V, 50pF
• Operating Temperature: 0°C ~ 70°C

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Series: 74ALS
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Package Considerations: Substitutes may differ in packaging format (Tape & Reel vs. Cut Tape) and package width specifications, provided the base package type remains 14-SOIC and all electrical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both SN74ALS05ANSR and SN74ALS05ADR are valid substitutes for the obsolete SN74ALS05ADRG4, as all critical electrical parameters are identical. The selection between substitutes should be based on the following factors:

SN74ALS05ANSR (MFR Recommended):

• Active product status ensures long-term availability
• Tape & Reel packaging suitable for automated assembly processes
• ROHS3 compliant and REACH unaffected
• Moisture Sensitivity Level 1 (Unlimited) matches original specification

SN74ALS05ADR (Parametric Equivalent):

• Active product status ensures long-term availability
• Cut Tape & Digi-Reel® packaging provides flexibility for lower-volume applications
• Identical package width (0.154", 3.90mm) to original part
• ROHS3 compliant and REACH unaffected
• Moisture Sensitivity Level 1 (Unlimited) matches original specification

Both substitutes maintain full electrical and functional equivalence to the main part. Selection should be based on procurement volume requirements and assembly process compatibility.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS05ANSR and SN74ALS05ADR be used interchangeably with SN74ALS05ADRG4?

A: Yes. Both substitutes are electrically and functionally equivalent. All critical parameters including logic type, circuit count, input/output specifications, voltage range, propagation delay, and operating temperature are identical. Differences exist only in packaging format and package width specifications.

Q: What is the difference between the packaging formats offered?

A: SN74ALS05ADRG4 is supplied in tube packaging. SN74ALS05ANSR is supplied in Tape & Reel format, optimized for high-volume automated assembly. SN74ALS05ADR is supplied in Cut Tape & Digi-Reel® format, suitable for mixed-volume applications. All three use the same 14-SOIC base package type.

Q: Does the package width difference affect circuit board compatibility?

A: The package width difference (0.154" vs. 0.209") refers to the physical width of the component body. Both are 14-SOIC packages with identical pin pitch and footprint. PCB layout compatibility depends on the specific footprint design used in your circuit board. Verify your PCB footprint specifications before selection.

Q: Are both substitutes compliant with current regulatory standards?

A: Yes. Both SN74ALS05ANSR and SN74ALS05ADR are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited), matching the original part's compliance status.

Q: Why is the main part marked as obsolete?

A: The SN74ALS05ADRG4 is classified as obsolete by the manufacturer. The active substitutes SN74ALS05ANSR and SN74ALS05ADR provide continued access to equivalent functionality with assured long-term availability.
