Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2432AIPW is determined by the following critical parameters:

Primary Substitution Criteria:

• Dual-channel configuration (Number of Circuits = 2)
• Rail-to-rail output capability
• 8-pin surface mount package (8-TSSOP or compatible 8-MSOP)
• Operating temperature range: -40°C to 85°C
• Supply voltage compatibility within 2.7 V to 10 V range
• ROHS3 compliance and EAR99 classification

Substitution Categories:

Category 1: Direct Functional Equivalents (Identical Electrical Performance) The TLV2432AIPWR is the manufacturer-recommended direct equivalent, differing only in packaging format (Tape & Reel versus Tube). All electrical specifications, series designation (LinCMOS™), and performance parameters are identical.

Category 2: Functional Alternatives (Compatible Electrical Performance with Parameter Variations) The MIC7122YMM and MIC7122YMM-TR (Microchip Technology) provide dual-channel rail-to-rail amplification in 8-MSOP packaging. These devices operate across a wider supply range (2.2 V to 15 V) and feature higher output current capability (250 mA per channel versus 50 mA). Trade-offs include higher supply current consumption (800 µA per channel versus 100 µA) and lower gain bandwidth product (420 kHz versus 550 kHz).

Category 3: Functional Alternatives (Different Amplifier Architecture) The OP279GRUZ-REEL (Analog Devices Inc.) is a buffer amplifier with dual channels in 8-TSSOP packaging. This device exhibits significantly different electrical characteristics: higher slew rate (3 V/µs versus 0.25 V/µs), higher gain bandwidth product (5 MHz versus 550 kHz), and higher input bias current (300 nA versus 1 pA). Supply voltage range is narrower (4.5 V to 12 V). This substitute is suitable only for applications where buffer amplification and higher bandwidth are required.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): The TLV2432AIPWR is the manufacturer-recommended substitute for the TLV2432AIPW. Both devices are manufactured by Texas Instruments, share identical electrical specifications, and operate within the same LinCMOS™ series. The only difference is packaging format: TLV2432AIPWR is supplied in Tape & Reel format, while TLV2432AIPW is supplied in Tube format. This substitute is appropriate for all applications currently using the TLV2432AIPW. The TLV2432AIPWR maintains Active product status, ensuring long-term availability and supply continuity.

For Applications Requiring Higher Output Current: The MIC7122YMM and MIC7122YMM-TR (Microchip Technology) are suitable substitutes for designs requiring higher output current capability (250 mA per channel versus 50 mA). These devices maintain dual-channel rail-to-rail configuration and identical input bias current (1 pA). However, designers must account for increased supply current consumption (800 µA per channel versus 100 µA) and reduced gain bandwidth product (420 kHz versus 550 kHz). Both MIC7122 variants are Active products with ROHS3 compliance. The MIC7122YMM-TR variant offers superior moisture sensitivity rating (MSL 1 versus MSL 2).

For Applications Requiring Higher Bandwidth: The OP279GRUZ-REEL (Analog Devices Inc.) is a buffer amplifier substitute suitable only for applications requiring significantly higher bandwidth (5 MHz gain bandwidth product) and faster slew rate (3 V/µs). This device is not recommended as a general replacement due to substantially different electrical characteristics, including higher input bias current (300 nA versus 1 pA) and higher input offset voltage (4 mV versus 300 µV). Additionally, the supply voltage range is narrower (4.5 V to 12 V), restricting use in low-voltage applications below 4.5 V. The OP279GRUZ-REEL is Active and ROHS3 compliant.

Compliance and Regulatory Considerations: All substitute parts listed maintain ROHS3 compliance and EAR99 classification, consistent with the original TLV2432AIPW. All devices operate across the -40°C to 85°C temperature range. Moisture sensitivity levels vary; designs requiring unlimited shelf life without baking should prioritize parts with MSL 1 rating (TLV2432AIPWR, MIC7122YMM-TR, OP279GRUZ-REEL).

Frequently Asked Questions (FAQ)

Q: Can the TLV2432AIPWR be used as a direct replacement for the TLV2432AIPW?

A: Yes. The TLV2432AIPWR is the manufacturer-recommended direct equivalent. Both devices are identical in electrical performance, series designation, and package type (8-TSSOP). The only difference is packaging format: TLV2432AIPWR uses Tape & Reel format while TLV2432AIPW uses Tube format. The TLV2432AIPWR is Active status, ensuring continued availability.

Q: What are the key differences between the TLV2432AIPW and the MIC7122YMM?

A: Both devices provide dual-channel rail-to-rail amplification in surface mount packages. The MIC7122YMM offers higher output current (250 mA versus 50 mA per channel) and wider supply voltage range (2.2 V to 15 V versus 2.7 V to 10 V). Trade-offs include higher supply current consumption (800 µA versus 100 µA per channel), lower gain bandwidth product (420 kHz versus 550 kHz), and higher input offset voltage (500 µV versus 300 µV). The MIC7122YMM uses 8-MSOP packaging instead of 8-TSSOP.

Q: Is the OP279GRUZ-REEL suitable as a general replacement for the TLV2432AIPW?

A: No. The OP279GRUZ-REEL is a buffer amplifier with fundamentally different electrical characteristics. While both are dual-channel rail-to-rail devices in 8-TSSOP packaging, the OP279GRUZ-REEL features significantly higher bandwidth (5 MHz versus 550 kHz), higher slew rate (3 V/µs versus 0.25 V/µs), and higher input bias current (300 nA versus 1 pA). The OP279GRUZ-REEL is suitable only for applications specifically requiring buffer amplification and higher bandwidth performance.

Q: What is the significance of the TLV2432AIPW being designated as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments will discontinue this part number after current inventory is depleted. No new production will occur. Designers should transition to the TLV2432AIPWR (Active status) or evaluate alternative substitutes to ensure long-term supply chain continuity.

Q: Can I use the MIC7122YMM in a design originally specified for the TLV2432AIPW?

A: Substitution is possible only if the application can tolerate the electrical differences. The MIC7122YMM has higher supply current consumption, lower gain bandwidth product, and higher input offset voltage. If the original design operates at supply voltages below 2.2 V, the MIC7122YMM is not suitable. If the design requires the 550 kHz gain bandwidth product of the TLV2432AIPW, the MIC7122YMM (420 kHz) may not meet performance requirements. Detailed circuit analysis is necessary.

Q: What are the packaging differences between the substitute parts?

A: The TLV2432AIPW and TLV2432AIPWR both use 8-TSSOP packaging (0.173" width, 4.40mm). The MIC7122YMM and MIC7122YMM-TR use 8-MSOP packaging (0.118" width, 3.00mm), which is physically smaller. The OP279GRUZ-REEL uses 8-TSSOP packaging identical to the original part. PCB layout modifications may be required when switching between TSSOP and MSOP packages.

Q: Which substitute part offers the best moisture sensitivity rating?

A: The TLV2432AIPWR, MIC7122YMM-TR, and OP279GRUZ-REEL all feature MSL 1 (Unlimited) rating, allowing unlimited shelf life without baking. The MIC7122YMM has MSL 2 (1 Year) rating, requiring baking before use if stored beyond one year. For applications with extended storage requirements, MSL 1 rated parts are preferred.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (TLV2432AIPWR, MIC7122YMM, MIC7122YMM-TR, OP279GRUZ-REEL) are ROHS3 compliant and carry EAR99 classification, consistent with the original TLV2432AIPW.
