Substitute Part Grouping Explanation

Substitution of the CBT3384D,112 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: 5 x 1:1 multiplexer topology
• Independent Circuits: 2 circuits per device
• Package Type: 24-SOIC form factor with 0.295" width (7.50mm)
• Voltage Supply Range: 4.5V ~ 5.5V single supply operation
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Technology: Surface mount only
• Compliance Standards: ROHS3 compliant, REACH unaffected

All substitute parts listed maintain identical electrical specifications and physical package dimensions, ensuring direct functional replacement without circuit redesign. Differences exist only in manufacturer (Texas Instruments vs. Nexperia), product status (active vs. last time buy vs. obsolete), and packaging format (cut tape, tape & reel, or tube).

Parameter Comparison

Engineering Selection Recommendations

For new design implementations, SN74CBT3384CDWR is the preferred substitute, as it maintains active product status with Texas Instruments, ensuring long-term availability and manufacturing support. This part is supplied in tape & reel format, standard for high-volume production environments.

For applications requiring immediate component availability with established supply chains, SN74CBTD3384CDW offers active status with the 74CBTD series variant, supplied in tube packaging suitable for lower-volume or prototype applications.

Parts designated as "Last Time Buy" (SN74CBT3384ADWR, SN74CBT3384ADW, SN74CBTD3384DW) remain functionally equivalent but indicate limited future availability from the manufacturer. These parts are suitable for legacy system maintenance and repair where existing inventory exists.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements equivalent to the original CBT3384D,112.

Frequently Asked Questions (FAQ)

Q: Can SN74CBT3384CDWR directly replace CBT3384D,112 without circuit modification?

A: Yes. Both parts share identical electrical specifications (5 x 1:1 configuration, 4.5V–5.5V supply, -40°C to 85°C operating range) and the same 24-SOIC package footprint. Direct substitution is possible without schematic or PCB layout changes.

Q: What is the difference between 74CBT and 74CBTD series variants?

A: Both series maintain identical electrical parameters and package form factors specified in this reference. The series designation reflects internal design variants from Texas Instruments. Functional equivalence is maintained across both series for the specified circuit configuration.

Q: Does packaging format (cut tape, tape & reel, tube) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Electrical characteristics and performance remain identical regardless of whether the part is supplied in cut tape, tape & reel, or tube format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance and REACH unaffected status, meeting current environmental regulations.

Q: Why is the original CBT3384D,112 marked as obsolete?

A: Obsolete status indicates the manufacturer (Nexperia) has discontinued production. The substitute parts from Texas Instruments provide equivalent functionality and are available through active or last-time-buy channels, ensuring design continuity.
