TLC2264AIN Equivalent & Substitute Parts

Part Overview

The TLC2264AIN is a general-purpose operational amplifier featuring four independent circuits in a 14-pin DIP package. This device is classified as a Last Time Buy product, indicating discontinued production with limited remaining inventory. The TLC2264AIN operates as a rail-to-rail output amplifier suitable for low-power analog signal processing applications across industrial, consumer, and instrumentation domains.

Finding equivalent substitute parts is necessary due to the Last Time Buy status of the TLC2264AIN. Identifying compatible alternatives ensures design continuity and supply chain reliability for new production runs and long-term product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC2264AIN is determined by electrical and mechanical parameter equivalence within the LinCMOS™ operational amplifier family. The critical parameters governing substitution are:

Electrical Equivalence Criteria:

• Amplifier type (General Purpose)
• Number of circuits (4 independent channels)
• Output configuration (Rail-to-Rail)
• Slew rate (0.55 V/µs)
• Gain bandwidth product (730 kHz)
• Input bias current (1 pA)
• Input offset voltage (300 µV)
• Supply current specifications
• Output current per channel (50 mA)
• Supply voltage range (4.4 V to 16 V)
• Operating temperature range (-40°C to 125°C)

Mechanical Compatibility Criteria:

• Package type and pin count
• Mounting technology (through-hole or surface-mount)
• Physical dimensions and footprint

The TLC2264IDR qualifies as a direct electrical substitute, sharing identical functional specifications and electrical performance. The primary difference is packaging format: the TLC2264IDR uses 14-SOIC surface-mount technology versus the 14-DIP through-hole configuration of the TLC2264AIN.

Parameter Comparison

Engineering Selection Recommendations

Electrical Compatibility: The TLC2264IDR provides complete electrical equivalence to the TLC2264AIN. All functional specifications, performance parameters, and electrical characteristics are identical. The TLC2264IDR exhibits marginally lower total supply current (800 µA versus 850 µA), representing a 50 µA reduction that is operationally insignificant and favorable for power-constrained applications.

Product Status and Supply Continuity: The TLC2264AIN carries Last Time Buy status with finite inventory (3,665 pieces). The TLC2264IDR maintains Active product status with substantially higher inventory availability (32,600 pieces), ensuring long-term supply reliability and design continuity for production programs requiring extended component availability.

Compliance and Regulatory Alignment: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying equivalent regulatory requirements for industrial and commercial applications.

Packaging and Integration Considerations: Selection between TLC2264AIN and TLC2264IDR depends on circuit board technology and assembly methodology. The TLC2264AIN requires through-hole mounting on PCBs with DIP sockets or through-hole pads. The TLC2264IDR requires surface-mount assembly capability and SOIC footprint design. Electrical performance is independent of packaging format.

Frequently Asked Questions (FAQ)

Q: Can the TLC2264IDR directly replace the TLC2264AIN in existing designs?

A: Electrical substitution is complete. The TLC2264IDR provides identical functional performance and electrical specifications. Physical substitution requires PCB redesign to accommodate the 14-SOIC surface-mount package instead of the 14-DIP through-hole package. Pin-to-pin electrical functionality is preserved.

Q: What is the significance of the 50 µA supply current difference?

A: The TLC2264IDR operates at 800 µA total supply current compared to 850 µA for the TLC2264AIN. This 50 µA reduction is within normal manufacturing tolerance variation and does not affect circuit performance or design specifications. The lower current consumption is operationally beneficial for battery-powered or power-limited applications.

Q: Why is the TLC2264AIN designated Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued production of the TLC2264AIN in 14-DIP through-hole packaging. The TLC2264IDR in 14-SOIC surface-mount packaging represents the active product line continuation. Existing inventory of TLC2264AIN is available for legacy system support, but new designs should transition to the TLC2264IDR.

Q: Are there any thermal or reliability differences between the packages?

A: The provided specifications do not include thermal resistance or reliability data. Both packages are manufactured by Texas Instruments using equivalent LinCMOS™ process technology. Package selection should be based on circuit board assembly capability and thermal management requirements of the specific application.

Q: What are the inventory implications for production planning?

A: The TLC2264AIN has limited inventory (3,665 pieces). The TLC2264IDR has substantially higher availability (32,600 pieces). For production programs requiring component quantities exceeding available TLC2264AIN stock, the TLC2264IDR is the recommended alternative to ensure supply continuity.

Q: Is the TLC2264IDR suitable for high-volume manufacturing?

A: Yes. The TLC2264IDR is designated Active product status with higher inventory levels and is available in Cut Tape and Digi-Reel® packaging formats, which are standard for automated surface-mount assembly processes. This packaging format supports high-volume production workflows.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the TLC2264AIN and TLC2264IDR are ROHS3 compliant and REACH Unaffected. They share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications, satisfying equivalent regulatory requirements for export and industrial applications.
