Substitute Part Grouping Explanation

Substitute parts for the CD74AC238M96G4 are identified based on strict equivalence across the following critical parameters:

• Circuit configuration: 1 x 3:8 decoder/demultiplexer
• Package type: 16-SOIC surface mount
• Electrical specifications: 1.5V ~ 5.5V supply voltage, 24mA output current (high and low)
• Operating temperature range: -55°C ~ 125°C
• Compliance certifications: ROHS3, MSL Level 1

Substitutes differ only in packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and product status (Active versus Discontinued), with no variation in electrical or mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both CD74AC138M96 and CD74AC238M96 are direct functional equivalents to the CD74AC238M96G4, with identical electrical and mechanical specifications. Selection between these alternatives should be based on:

1. Product Status: Both substitute parts maintain Active status, ensuring continued availability and supply chain stability compared to the discontinued original part.

2. Compliance: All three parts maintain ROHS3 compliance and MSL Level 1 rating, meeting regulatory and environmental requirements.

3. Packaging Format: CD74AC138M96 is available in Cut Tape & Digi-Reel format, while CD74AC238M96 is supplied in Tape & Reel format. Selection depends on procurement volume and assembly line requirements.

Frequently Asked Questions (FAQ)

Q: Can CD74AC138M96 and CD74AC238M96 be used interchangeably with CD74AC238M96G4?

A: Yes. Both parts are parametric equivalents with identical circuit configuration (1 x 3:8), package type (16-SOIC), electrical specifications (1.5V ~ 5.5V supply, 24mA output current), and operating temperature range (-55°C ~ 125°C). The only differences are packaging format and product status.

Q: What is the difference between Cut Tape & Digi-Reel and Tape & Reel packaging?

A: Both are surface mount delivery formats for 16-SOIC components. Cut Tape & Digi-Reel is suitable for smaller volume orders, while Tape & Reel is optimized for high-volume automated assembly. Electrical and mechanical performance are identical.

Q: Are there any compliance or certification differences between the substitute parts?

A: No. All three parts maintain identical ROHS3 compliance status and MSL Level 1 rating. No additional testing or qualification is required when substituting between these parts.

Q: Why is the original CD74AC238M96G4 discontinued?

A: Product discontinuation is a supplier decision unrelated to technical performance. The substitute parts CD74AC138M96 and CD74AC238M96 provide identical functionality and remain in active production.

Q: Can these parts be used in new designs?

A: Yes. Both CD74AC138M96 and CD74AC238M96 are Active products suitable for new designs. They meet all regulatory requirements and maintain full electrical and mechanical compatibility with the original specification.
