Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BUF11704AIPWPR is determined by strict alignment with the following critical parameters:

Mechanical Compatibility:

• Identical package type: 28-PowerTSSOP (0.173", 4.40mm Width)
• Surface mount mounting type
• Pin-to-pin compatibility

Functional Equivalence:

• Number of circuits: 10 independent amplifier channels
• Output configuration: Rail-to-rail capability
• Application domain: TFT-LCD panel gamma buffer and VCOM driver functionality
• Bandwidth: 1 MHz (-3dB)
• Slew rate: 1.6V/µs

Electrical Operating Range:

• Supply voltage range must encompass or overlap with the original specification
• Supply current: 5 mA
• Compliance certifications: RoHS3, REACH Unaffected

The BUF11705AIPWPR qualifies as a manufacturer-recommended substitute based on identical mechanical packaging, matching functional circuit count and configuration, equivalent bandwidth and slew rate specifications, and compatible supply current characteristics. The substitute part operates within an extended supply voltage range (7V ~ 22V), which encompasses the upper portion of the original part's operating window.

Parameter Comparison

Engineering Selection Recommendations

The BUF11705AIPWPR is the manufacturer-recommended substitute for the BUF11704AIPWPR. Both components share identical mechanical packaging, functional circuit architecture, and core electrical performance characteristics. The substitute part maintains full RoHS3 compliance and equivalent moisture sensitivity ratings.

The primary distinction between these parts is the supply voltage operating range. The BUF11705AIPWPR specifies 7V ~ 22V, compared to the original part's 4.5V ~ 18V range. Applications operating within the overlapping voltage window (7V ~ 18V) experience no functional limitation. Systems requiring operation below 7V supply voltage cannot use the BUF11705AIPWPR as a direct substitute without circuit redesign.

Both components carry "Not For New Designs" status from Texas Instruments, indicating that neither part is recommended for new product development initiatives. For legacy system maintenance and production continuation, the BUF11705AIPWPR provides functional equivalence with documented manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the BUF11705AIPWPR replace the BUF11704AIPWPR in all applications?

A: The BUF11705AIPWPR provides functional substitution for applications operating within the overlapping supply voltage range of 7V ~ 18V. Applications requiring operation at supply voltages below 7V require the original BUF11704AIPWPR or alternative component selection.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the BUF11704AIPWPR and BUF11705AIPWPR use the 28-PowerTSSOP package with dimensions of 0.173" × 4.40mm width. PCB layout and footprint designs are directly compatible.

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

A: This designation indicates that Texas Instruments has concluded active development and long-term support for these components. Both the original part and its substitute carry this status. New product designs should evaluate alternative amplifier solutions from current Texas Instruments product lines.

Q: Are the circuit counts and output configurations identical?

A: Yes. Both parts contain 10 independent amplifier circuits with rail-to-rail output capability, designed for TFT-LCD gamma buffer and VCOM driver applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the BUF11704AIPWPR and BUF11705AIPWPR are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 2 (1 Year).

Q: What is the primary technical difference between these parts?

A: The supply voltage operating range differs. The BUF11704AIPWPR operates from 4.5V ~ 18V, while the BUF11705AIPWPR operates from 7V ~ 22V. All other electrical and functional parameters are identical.
