Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74FST3384DWR2 is determined by the following critical parameters:

• Circuit Configuration: 5 x 1:1 bus switch topology
• Independent Circuits: 2 circuits
• Package Type: 24-SOIC form factor with identical 0.295" (7.50mm) width
• Voltage Supply Range: Single supply operation
• Operating Temperature Range: -40°C to 85°C
• Mounting Type: Surface mount technology

All substitute parts listed maintain identical electrical functionality and physical compatibility with the original 74FST3384DWR2. The Texas Instruments SN74CBT3384 series parts satisfy all substitution criteria through matching circuit topology, package specifications, and operating parameters.

Parameter Comparison

Engineering Selection Recommendations

SN74CBT3384CDWR is the primary substitute for new designs and production. This part carries Active product status from Texas Instruments and maintains ROHS3 compliance, ensuring long-term availability and regulatory alignment. The SN74CBT3384CDWR is supplied in Tape & Reel packaging with 3026 units in current inventory.

SN74CBT3384ADWR serves as an alternative direct substitute with Last Time Buy status. This variant is supplied in Cut Tape packaging and maintains identical electrical and mechanical specifications. Inventory availability is 3164 units.

SN74CBT3384ADW functions as a compatible substitute with Last Time Buy status, supplied in Tube packaging with 3900 units available. This option is suitable for applications where packaging format does not impose constraints.

All three Texas Instruments substitutes provide ROHS3 compliance, addressing the RoHS non-compliance status of the original 74FST3384DWR2. The voltage supply range for Texas Instruments parts begins at 4.5V, which is compatible with the 74FST3384DWR2 minimum of 4V for applications operating at or above 4.5V.

Frequently Asked Questions (FAQ)

Q: Can SN74CBT3384 series parts directly replace the 74FST3384DWR2?

A: Yes. The SN74CBT3384 series maintains identical circuit topology (5 x 1:1), independent circuit count (2), package type (24-SOIC), and operating temperature range (-40°C to 85°C). All three substitute variants are electrically and mechanically compatible.

Q: What is the difference between SN74CBT3384ADW, SN74CBT3384ADWR, and SN74CBT3384CDWR?

A: The primary differences are packaging format and product status. SN74CBT3384ADW uses Tube packaging, SN74CBT3384ADWR uses Cut Tape packaging, and SN74CBT3384CDWR uses Tape & Reel packaging. SN74CBT3384CDWR carries Active status, while the other two are Last Time Buy.

Q: Does the voltage supply range difference affect compatibility?

A: The 74FST3384DWR2 operates at 4V to 5.5V, while Texas Instruments substitutes operate at 4.5V to 5.5V. For applications requiring operation below 4.5V, the original part must be retained. For applications operating at 4.5V and above, substitutes are fully compatible.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three SN74CBT3384 variants are ROHS3 compliant, addressing the RoHS non-compliance of the original 74FST3384DWR2.

Q: Which substitute should be selected for new production?

A: SN74CBT3384CDWR is recommended for new production due to Active product status, ensuring sustained availability and support from Texas Instruments.
