Key Parameters

Substitute Part Grouping Explanation

Substitution of the BUF07704AIPWPR is determined by the following critical parameters:

Maintained Characteristics (Required for Substitution):

• Manufacturer: Texas Instruments
• Application domain: TFT-LCD Panels (Gamma Buffer, VCOM Driver)
• Output Type: Rail-to-Rail
• -3dB Bandwidth: 1 MHz
• Slew Rate: 1.6 V/µs
• Current - Supply: 5 mA
• Mounting Type: Surface Mount
• RoHS3 Compliance
• MSL Rating: 2 (1 Year)

Variable Characteristics (Allowable Differences):

• Number of Circuits: 6 (main part) vs. 10 (substitute)
• Voltage - Supply Range: 4.5V ~ 18V (main part) vs. 7V ~ 22V (substitute)
• Package / Case: 20-PowerTSSOP vs. 28-PowerTSSOP
• Product Status: Active vs. Not For New Designs
• Inventory availability

The BUF11705AIPWPR qualifies as a substitute when applications require increased circuit count (10 vs. 6) or higher supply voltage tolerance, provided the design accommodates the larger 28-pin package footprint.

Parameter Comparison

Engineering Selection Recommendations

BUF07704AIPWPR Selection Criteria:

• Primary choice for new TFT-LCD amplifier designs requiring six independent circuits
• Active product status ensures long-term availability and manufacturing support
• Supply voltage range of 4.5V ~ 18V accommodates standard single-supply and dual-supply configurations
• 20-pin package footprint suitable for space-constrained PCB layouts
• ROHS3 compliance and MSL 2 rating meet current environmental and reliability standards

BUF11705AIPWPR Selection Criteria:

• Applicable when design architecture requires ten amplifier circuits instead of six
• Higher supply voltage range (7V ~ 22V) for applications requiring extended voltage tolerance
• 28-pin package requires larger PCB footprint allocation
• Not For New Designs status indicates this part is in mature/legacy phase; use only when existing designs or specific legacy system requirements mandate this configuration
• Lower inventory (727 units) compared to BUF07704AIPWPR (25,400 units)

Both parts maintain identical core performance specifications (bandwidth, slew rate, supply current) and compliance certifications, ensuring functional equivalence within their respective circuit count and voltage range parameters.

Frequently Asked Questions (FAQ)

Q: Can BUF11705AIPWPR directly replace BUF07704AIPWPR in existing designs?

A: Direct replacement is not recommended without PCB redesign. The BUF11705AIPWPR uses a 28-pin package versus the 20-pin package of BUF07704AIPWPR, requiring different footprint layouts. Additionally, the BUF11705AIPWPR provides ten circuits instead of six, which may introduce unused functionality and increased board complexity.

Q: What is the significance of the "Not For New Designs" status on BUF11705AIPWPR?

A: This designation indicates the part is in legacy/mature phase. Texas Instruments continues to support existing designs using this part, but recommends BUF07704AIPWPR for new development projects. New designs should prioritize the Active-status BUF07704AIPWPR.

Q: Are the amplifier performance characteristics identical between these parts?

A: Yes. Both parts share identical -3dB bandwidth (1 MHz), slew rate (1.6 V/µs), and supply current (5 mA) specifications. The primary differences are circuit count and supply voltage range.

Q: What supply voltage considerations apply when selecting between these parts?

A: BUF07704AIPWPR operates from 4.5V to 18V. BUF11705AIPWPR operates from 7V to 22V. If your application requires supply voltages below 7V, BUF07704AIPWPR is the only viable option. For supplies above 18V but below 22V, only BUF11705AIPWPR is suitable.

Q: Do both parts meet current environmental compliance requirements?

A: Yes. Both BUF07704AIPWPR and BUF11705AIPWPR are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.

Q: How does circuit count affect substitution decisions?

A: Circuit count (6 vs. 10) determines the number of independent amplifier channels available. Select BUF07704AIPWPR if your TFT-LCD design requires six gamma buffer or VCOM driver channels. Select BUF11705AIPWPR only if your design specifically requires ten channels and can accommodate the larger 28-pin package.
