TLV2765CDR Equivalent & Substitute Parts

Part Overview

The TLV2765CDR is a general-purpose operational amplifier manufactured by Texas Instruments, configured as a 4-circuit rail-to-rail amplifier in a 16-SOIC surface mount package. This device is designated as Last Time Buy, indicating discontinued production status. The TLV2765CDR operates across a supply voltage range of 1.8 V to 3.6 V with low input bias current and minimal input offset voltage, making it suitable for low-power analog signal conditioning applications.

Due to its Last Time Buy status, identifying equivalent substitute parts is essential for design continuity and long-term component availability. Substitute parts must maintain functional equivalence across critical electrical parameters while accommodating package and operational temperature variations.

Substitute Part Grouping Explanation

Substitution of the TLV2765CDR is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 4
• Output Type: Rail-to-Rail
• Slew Rate: 0.23 V/µs
• Gain Bandwidth Product: 500 kHz
• Current - Input Bias: 3 pA
• Voltage - Input Offset: 550 µV
• Current - Supply: 20 µA (per 4 channels)
• Current - Output / Channel: 10.2 mA
• Voltage - Supply Span: 1.8 V to 3.6 V

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package compatibility with 16-SOIC or equivalent pinout configuration

Compliance Criteria:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The TLV2764IDR is identified as the manufacturer-recommended substitute. This part maintains identical electrical specifications and RoHS3 compliance. The primary differences are package configuration (14-SOIC versus 16-SOIC) and extended operating temperature range (-40°C to 85°C versus 0°C to 70°C), with Active product status ensuring continued availability.

Engineering Selection Recommendations

Primary Substitute: TLV2764IDR

The TLV2764IDR is the manufacturer-recommended substitute for the TLV2765CDR. This selection is based on the following engineering factors:

1. Electrical Equivalence: All critical electrical parameters are identical, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current specifications. The device maintains the same 1.8 V to 3.6 V supply voltage range.

2. Product Status: The TLV2764IDR holds Active product status, ensuring long-term availability and continued manufacturing support, whereas the TLV2765CDR is designated Last Time Buy.

3. Compliance Certification: Both parts maintain ROHS3 compliance and identical Moisture Sensitivity Level (MSL 1 - Unlimited), ensuring regulatory and environmental compatibility.

4. Operating Temperature Consideration: The TLV2764IDR provides an extended operating temperature range (-40°C to 85°C) compared to the TLV2765CDR (0°C to 70°C). This extended range offers greater flexibility for applications requiring operation outside the original temperature specification.

5. Package Difference: The TLV2764IDR uses a 14-SOIC package versus the 16-SOIC package of the TLV2765CDR. Both packages maintain the same 0.154" (3.90mm) width. PCB layout modifications are required to accommodate the different pin count and pinout configuration.

Design Transition Path: For new designs or redesigns, the TLV2764IDR should be selected. For existing designs using the TLV2765CDR, a formal design review and PCB layout revision are necessary to implement the TLV2764IDR substitute.

Frequently Asked Questions (FAQ)

Q1: Can the TLV2764IDR be used as a direct pin-for-pin replacement for the TLV2765CDR?

A: No. The TLV2764IDR uses a 14-SOIC package while the TLV2765CDR uses a 16-SOIC package. The pin count and pinout configuration differ. PCB layout and schematic modifications are required. Consult the respective device datasheets for detailed pinout information before implementing this substitute.

Q2: Are the electrical specifications identical between the TLV2765CDR and TLV2764IDR?

A: Yes. Both devices share identical electrical specifications for slew rate (0.23 V/µs), gain bandwidth product (500 kHz), input bias current (3 pA), input offset voltage (550 µV), supply current (20 µA per channel), output current (10.2 mA per channel), and supply voltage range (1.8 V to 3.6 V).

Q3: What is the significance of the TLV2765CDR being designated as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part. Existing inventory will be depleted, and no future manufacturing runs are planned. The TLV2764IDR, with Active status, is the recommended alternative for continued component availability.

Q4: Does the extended operating temperature range of the TLV2764IDR (-40°C to 85°C) affect compatibility?

A: The extended temperature range of the TLV2764IDR is a superset of the TLV2765CDR range (0°C to 70°C). This provides greater operational flexibility. However, applications originally designed for the 0°C to 70°C range will function identically with the TLV2764IDR. No performance degradation occurs within the original temperature specification.

Q5: Are both parts RoHS3 compliant?

A: Yes. Both the TLV2765CDR and TLV2764IDR are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). They meet identical environmental and regulatory requirements.

Q6: What packaging format differences exist between these parts?

A: The TLV2765CDR is supplied in Tape & Reel (TR) format, while the TLV2764IDR is available in Cut Tape (CT) and Digi-Reel® format. These are supply chain and handling considerations that do not affect electrical performance or component functionality.

Q7: Should I redesign my PCB to use the TLV2764IDR?

A: For new designs, the TLV2764IDR should be selected due to its Active product status and extended temperature range. For existing designs currently using the TLV2765CDR, a cost-benefit analysis should be performed. If the TLV2765CDR inventory is sufficient for the product lifecycle, redesign may not be necessary. If long-term availability is required, PCB redesign to accommodate the TLV2764IDR is recommended.
