TLV2342IDR Equivalent & Substitute Parts

Part Overview

The TLV2342IDR is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, designed for low-power analog signal processing applications. This device integrates two independent amplifier circuits in an 8-SOIC surface mount package and operates across a wide supply voltage range of 2V to 8V.

The TLV2342IDR carries an Obsolete product status, indicating that Texas Instruments has discontinued active production and support for this part number. This obsolescence necessitates identification of functionally equivalent substitute components to maintain design continuity and ensure long-term component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2342IDR is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: CMOS technology
• Number of Circuits: Dual-channel (2 independent amplifiers)
• Slew Rate: 3.6 V/µs
• Gain Bandwidth Product: 1.7 MHz
• Input Bias Current: 0.6 pA
• Input Offset Voltage: 1.1 mV
• Supply Current: 1.4 mA per channel
• Output Current Capability: 30 mA per channel
• Supply Voltage Range: 2V to 8V minimum and maximum
• Operating Temperature: -40°C to 85°C

Mechanical and Compliance Equivalence Criteria:

• Surface mount technology
• RoHS3 compliance
• Moisture Sensitivity Level 1

The TLV2342IPW qualifies as a manufacturer-recommended substitute because it maintains identical electrical specifications and operating characteristics while differing only in package form factor (8-TSSOP versus 8-SOIC) and product lifecycle status (Last Time Buy versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The TLV2342IPW is the manufacturer-recommended substitute for the obsolete TLV2342IDR. Both components share identical electrical performance specifications, supply voltage requirements, and operating temperature ranges. The substitution is valid from an electrical and functional standpoint.

Lifecycle Consideration: The TLV2342IPW carries a Last Time Buy status, indicating limited future availability. Long-term design strategies should account for this constraint.

Package Consideration: The primary difference between these parts is the package form factor. The TLV2342IDR uses an 8-SOIC package (0.154" width, 3.90mm), while the TLV2342IPW uses an 8-TSSOP package (0.173" width, 4.40mm). PCB layout modifications are required to accommodate the different package dimensions and pin pitch. Both packages are surface mount technologies with identical pin counts and functional pin assignments.

Compliance: Both components maintain ROHS3 compliance and Moisture Sensitivity Level 1 (unlimited shelf life), ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the TLV2342IPW directly replace the TLV2342IDR without circuit modifications?

A: The TLV2342IPW is electrically equivalent to the TLV2342IDR and will function identically in the circuit. However, PCB layout modifications are required due to the different package form factors (8-SOIC versus 8-TSSOP). The pin assignments are functionally equivalent, but the physical dimensions and pin spacing differ.

Q: What is the difference between 8-SOIC and 8-TSSOP packages?

A: Both are 8-pin surface mount packages. The 8-SOIC (Small Outline Integrated Circuit) has a body width of 0.154" (3.90mm), while the 8-TSSOP (Thin Shrink Small Outline Package) has a body width of 0.173" (4.40mm). The TSSOP package is slightly wider and has a different pin pitch configuration. PCB footprints are not interchangeable without design modification.

Q: Are there any electrical performance differences between TLV2342IDR and TLV2342IPW?

A: No. Both components have identical electrical specifications including slew rate (3.6 V/µs), gain bandwidth product (1.7 MHz), input bias current (0.6 pA), input offset voltage (1.1 mV), supply current (1.4 mA per channel), output current (30 mA per channel), and operating temperature range (-40°C to 85°C).

Q: What does "Last Time Buy" status mean for the TLV2342IPW?

A: Last Time Buy indicates that Texas Instruments has announced a final production run for this part number. After the Last Time Buy date, the component will no longer be manufactured. Designers should plan accordingly for long-term component sourcing.

Q: Are both parts RoHS compliant?

A: Yes. Both the TLV2342IDR and TLV2342IPW are ROHS3 compliant and have Moisture Sensitivity Level 1 (unlimited shelf life), meeting current environmental and manufacturing standards.

Q: Can I use the TLV2342IPW in new designs if the TLV2342IDR is obsolete?

A: Yes, the TLV2342IPW is the manufacturer-recommended substitute and is suitable for new designs. However, designers should be aware of its Last Time Buy status and plan for alternative solutions if long-term component availability becomes critical.
