TLV2264QD Equivalent & Substitute Parts

Part Overview

The TLV2264QD is a CMOS amplifier integrated circuit containing four independent operational amplifier circuits in a 14-SOIC surface mount package. This device features rail-to-rail output capability and operates across a 2.7V to 8V supply voltage range, making it suitable for low-power analog signal processing applications. The TLV2264QD is designated as Last Time Buy, indicating that this specific packaging configuration (Tube) is no longer in active production. Identifying equivalent substitute parts is necessary to ensure continued design support and procurement availability for new production runs and design revisions.

Substitute Part Grouping Explanation

The TLV2264QD and its substitute TLV2264AIDR share the same base product number (TLV2264) and are manufactured by Texas Instruments within the LinCMOS™ series. Both devices are functionally equivalent as four-channel CMOS amplifiers with identical core electrical specifications: 0.55V/µs slew rate, 710 kHz gain bandwidth product, 300µV input offset voltage, 50mA output current per channel, and 2.7V to 8V supply voltage range.

The primary distinction between these parts is packaging format and product status. The TLV2264QD is supplied in Tube packaging and carries Last Time Buy status, while the TLV2264AIDR is supplied in Tape & Reel (TR) format and maintains Active product status. Both devices are housed in the identical 14-SOIC package footprint and are suitable for surface mount assembly.

Secondary differences exist in supply current specifications: the TLV2264QD draws 1.5mA across four channels, while the TLV2264AIDR draws 800µA across four channels. The TLV2264AIDR also specifies a lower input bias current of 1pA compared to the TLV2264QD at 50pA. These differences do not affect functional substitution for applications where the lower power consumption and reduced input bias current of the TLV2264AIDR are acceptable or beneficial.

Substitution is valid based on the following criteria:

• Identical amplifier type (CMOS)
• Identical number of circuits (4)
• Identical output type (Rail-to-Rail)
• Identical slew rate (0.55V/µs)
• Identical gain bandwidth product (710 kHz)
• Identical input offset voltage (300µV)
• Identical output current per channel (50mA)
• Identical supply voltage range (2.7V to 8V)
• Identical operating temperature range (-40°C to 125°C)
• Identical package footprint (14-SOIC)
• Identical mounting type (Surface Mount)

Parameter Comparison

Engineering Selection Recommendations

The TLV2264AIDR is the manufacturer-recommended substitute for the TLV2264QD. This substitution is valid for all applications where the TLV2264QD was previously specified.

The TLV2264AIDR maintains Active product status with Texas Instruments, ensuring long-term availability and continued manufacturing support. The TLV2264QD, designated as Last Time Buy, will reach end-of-life and become unavailable for future procurement. Designs currently using the TLV2264QD should transition to the TLV2264AIDR to maintain supply chain continuity.

Both devices are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, meeting identical regulatory and environmental requirements. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

The TLV2264AIDR offers improved electrical characteristics with reduced input bias current (1pA versus 50pA) and lower supply current consumption (800µA versus 1.5mA across four channels). These improvements do not compromise functionality and provide enhanced performance in low-power and precision analog applications.

The primary consideration for substitution is packaging format. The TLV2264QD is supplied in Tube packaging, while the TLV2264AIDR is supplied in Tape & Reel (TR) format. Both devices use the identical 14-SOIC surface mount package footprint, ensuring PCB-level compatibility without design modification. Tape & Reel packaging is standard for high-volume production and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the TLV2264AIDR be used as a direct replacement for the TLV2264QD on existing PCBs?

A: Yes. Both devices use the identical 14-SOIC package footprint with 0.154" (3.90mm) width. No PCB layout modifications are required. The devices are pin-compatible and functionally equivalent for all specified electrical parameters.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in plastic tubes suitable for manual handling and small-quantity applications. Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, designed for automated pick-and-place assembly equipment used in high-volume production. Both formats contain the same component in the same package footprint.

Q: Are there any electrical performance differences between the TLV2264QD and TLV2264AIDR?

A: The core amplifier specifications are identical. The TLV2264AIDR specifies lower input bias current (1pA versus 50pA) and lower supply current consumption (800µA versus 1.5mA across four channels). These represent improved performance characteristics that do not affect substitution validity.

Q: Why is the TLV2264QD designated as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this specific packaging configuration. Existing inventory will be sold until depletion, after which the part will become unavailable. The TLV2264AIDR in Tape & Reel format remains in active production.

Q: Are both devices suitable for automotive applications?

A: The TLV2264QD carries Automotive grade qualification with AEC-Q100 certification. The TLV2264AIDR specifications provided do not explicitly list automotive qualification. Verify automotive suitability requirements with the device datasheet or manufacturer if automotive-grade certification is a design requirement.

Q: What is the operating temperature range for both devices?

A: Both the TLV2264QD and TLV2264AIDR operate across -40°C to 125°C (TA), providing identical temperature performance for industrial and extended-temperature applications.

Q: Are both devices RoHS compliant?

A: Yes. Both the TLV2264QD and TLV2264AIDR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the supply voltage range for these devices?

A: Both devices operate with a supply voltage span of 2.7V minimum to 8V maximum, providing flexibility for single-cell battery applications through standard 5V and 8V supply systems.

Q: Can the TLV2264AIDR be used in designs originally specified for the TLV2264QD without circuit modifications?

A: Yes. The electrical specifications, package footprint, and pin configuration are identical. No circuit modifications are required. The substitution is direct and transparent to the circuit design.
