Substitute Part Grouping Explanation

Substitution of the FSTU32160MTDX is determined by strict equivalence across the following parameters:

• Circuit configuration: 16 x 1:2 multiplexer/demultiplexer topology
• Package type: 56-TFSOP (56-TSSOP) surface mount
• Voltage supply: Single supply operation within 4V to 5.5V range
• Operating temperature: -40°C to 85°C industrial range
• Independent circuits: 1 circuit per device

The SN74CBT16232DGGR from Texas Instruments meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SN74CBT16232DGGR is the direct substitute for the obsolete FSTU32160MTDX. Both components share identical circuit topology, package form factor, and core electrical specifications. The substitute part offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance meets current environmental regulations
• Improved moisture sensitivity level (MSL 1 vs. MSL 2) provides extended shelf life without moisture bake-out requirements
• Minimum supply voltage specification of 4.5V (versus 4V) remains compatible with standard 5V logic systems

The substitute part is suitable for direct replacement in existing designs and new implementations requiring 16 x 1:2 multiplexer/demultiplexer functionality in 56-TSSOP packaging.

Frequently Asked Questions (FAQ)

Q: Can the SN74CBT16232DGGR replace the FSTU32160MTDX in existing designs?

A: Yes. Both parts share identical circuit configuration (16 x 1:2), package type (56-TFSOP/56-TSSOP), operating temperature range (-40°C to 85°C), and single supply voltage operation. The substitute part is a direct functional equivalent.

Q: What is the difference in supply voltage specifications?

A: The FSTU32160MTDX operates from 4V to 5.5V, while the SN74CBT16232DGGR operates from 4.5V to 5.5V. In standard 5V logic applications, this difference is not significant. Systems operating below 4.5V require verification of circuit behavior.

Q: Why is moisture sensitivity level different between the two parts?

A: The SN74CBT16232DGGR has MSL 1 (unlimited shelf life), compared to MSL 2 (1 year) for the FSTU32160MTDX. This indicates improved moisture resistance in the substitute part and reduces handling and storage requirements.

Q: Are both parts available in the same packaging?

A: Yes. Both the FSTU32160MTDX and SN74CBT16232DGGR are supplied in 56-TFSOP (56-TSSOP) surface mount packages with identical pin counts and footprints.

Q: What compliance certifications apply to the substitute part?

A: The SN74CBT16232DGGR is ROHS3 compliant and REACH unaffected. Both parts carry EAR99 export classification and share the same HTSUS code (8542.39.0001).
