Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74VHC153MX is determined by the following critical parameters:

• Functional Circuit: 2 x 4:1 multiplexer configuration with identical pin functionality
• Package Type: 16-SOIC surface mount package with matching 0.154" (3.90mm) width
• Supply Voltage Compatibility: Minimum supply voltage must not exceed the 74VHC153MX operating range; maximum supply voltage must accommodate 5.5V operation
• Output Current Capability: Substitute must meet or exceed 8mA output current specification
• Operating Temperature Range: Substitute must support the required application temperature window
• Mounting Technology: Surface mount configuration for PCB assembly compatibility

The CD74AC153M96 from Texas Instruments meets all substitution criteria as an active product with identical multiplexer circuit topology and package specification.

Engineering Selection Recommendations

The CD74AC153M96 is the qualified substitute for the obsolete 74VHC153MX. Selection rationale is based on the following factors:

Product Status: The CD74AC153M96 maintains active production status with Texas Instruments, ensuring long-term availability and supply chain stability compared to the obsolete 74VHC153MX.

Compliance & Certifications: Both parts maintain identical REACH Unaffected status and EAR99 export classification. The CD74AC153M96 carries RoHS3 compliance certification, meeting current regulatory requirements for new designs.

Electrical Performance: The CD74AC153M96 provides enhanced output current capability (24mA versus 8mA), expanded operating temperature range (-55°C to 125°C versus -40°C to 85°C), and extended minimum supply voltage support (1.5V versus 2V). These improvements ensure compatibility with the 74VHC153MX application envelope while offering additional design margin.

Package Compatibility: Identical 16-SOIC package specification ensures direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the CD74AC153M96 directly replace the 74VHC153MX without PCB modifications?

A: Yes. Both components use the 16-SOIC package with identical pinout and footprint dimensions (0.154" width, 3.90mm). No PCB layout changes are required for physical substitution.

Q: What are the key electrical differences between these parts?

A: The CD74AC153M96 provides higher output current (24mA versus 8mA), wider operating temperature range (-55°C to 125°C versus -40°C to 85°C), and lower minimum supply voltage (1.5V versus 2V). These represent performance enhancements that maintain backward compatibility with 74VHC153MX applications.

Q: Is the CD74AC153M96 suitable for new designs?

A: Yes. The CD74AC153M96 is an active product with current production status, RoHS3 compliance, and full regulatory support, making it appropriate for new design implementations.

Q: Are there any supply voltage considerations when substituting?

A: The CD74AC153M96 supports a lower minimum supply voltage (1.5V) compared to the 74VHC153MX (2V). Applications operating at 2V or higher will function identically. Applications requiring operation below 2V require the CD74AC153M96 specifically.

Q: What is the moisture sensitivity level for both parts?

A: Both the 74VHC153MX and CD74AC153M96 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
