TLC2264CPW Equivalent & Substitute Parts

Part Overview

The TLC2264CPW is a general-purpose operational amplifier featuring four independent circuits in a 14-TSSOP surface mount package. Manufactured by Texas Instruments under the LinCMOS™ series, this device provides rail-to-rail output capability with low input bias current and is designed for applications requiring precision analog signal processing. The TLC2264CPW is classified as obsolete, necessitating identification of active equivalent and substitute components that maintain functional and electrical compatibility for ongoing production and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC2264CPW is determined by strict electrical and mechanical compatibility across the following critical parameters:

Mechanical Compatibility: All substitute parts must use the 14-TSSOP surface mount package with identical 0.173" (4.40mm) width to ensure PCB layout compatibility without redesign.

Functional Compatibility: All substitute parts must provide four independent general-purpose operational amplifier circuits with rail-to-rail output capability.

Electrical Operating Range: Substitute parts must support the supply voltage range of 4.4 V to 16 V minimum to maximum. Parts with extended lower supply limits (3.5 V) remain compatible as they encompass the original specification.

Output Current Capability: All substitute parts must deliver minimum 50 mA per channel output current to satisfy load requirements.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and MSL 1 rating to ensure environmental and manufacturing process compatibility.

The TLC2264CPWR represents a direct equivalent from Texas Instruments with identical electrical specifications but different packaging format (Cut Tape & Digi-Reel® versus Tube). The MCP6H04-E/ST and MCP6H04T-E/ST from Microchip Technology are functional substitutes with enhanced performance characteristics and extended operating temperature range, suitable for applications where the original specifications are met or exceeded.

Parameter Comparison

Engineering Selection Recommendations

TLC2264CPWR (Texas Instruments): This part is the recommended primary substitute. It maintains identical electrical specifications to the TLC2264CPW across all critical parameters including slew rate, gain bandwidth product, input bias current, and supply current. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tube), which does not affect electrical performance or PCB compatibility. Product status is Active, ensuring long-term availability and supply chain stability. This selection is appropriate for direct replacement in existing designs without circuit modification.

MCP6H04-E/ST and MCP6H04T-E/ST (Microchip Technology): These parts are functional substitutes suitable for applications where enhanced performance characteristics are acceptable. Both devices exceed the original TLC2264CPW specifications in slew rate (0.8 V/µs versus 0.55 V/µs) and gain bandwidth product (1.2 MHz versus 730 kHz), providing improved frequency response. Extended operating temperature range (-40°C to 125°C versus 0°C to 70°C) accommodates wider environmental conditions. Reduced supply current (135 µA versus 850 µA across four channels) offers power efficiency benefits. Both maintain 14-TSSOP package compatibility, ROHS3 compliance, and MSL 1 rating. The MCP6H04-E/ST is supplied in Tube packaging, while MCP6H04T-E/ST is supplied in Tape & Reel format. Selection between these two depends on procurement and assembly requirements rather than electrical performance.

All three substitute parts are currently in active production status with confirmed inventory availability, ensuring reliable sourcing for new designs and legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can TLC2264CPWR be used as a direct replacement for TLC2264CPW?

A: Yes. The TLC2264CPWR is electrically identical to the TLC2264CPW across all specified parameters. The difference is packaging format: TLC2264CPW is supplied in Tube, while TLC2264CPWR is supplied in Cut Tape & Digi-Reel® format. Both use the same 14-TSSOP package and are pin-compatible. Selection depends on assembly line requirements and procurement preferences.

Q: Are the Microchip MCP6H04 parts compatible with TLC2264CPW designs?

A: The MCP6H04-E/ST and MCP6H04T-E/ST are functionally compatible substitutes. Both provide four rail-to-rail operational amplifier circuits in the same 14-TSSOP package. All critical electrical parameters meet or exceed TLC2264CPW specifications: output current capability (50 mA per channel), supply voltage range (3.5 V to 16 V encompasses the original 4.4 V to 16 V), and output type (rail-to-rail). Pin configuration and package dimensions are identical, enabling direct PCB substitution without layout modification.

Q: What are the key differences between TLC2264CPW and MCP6H04 devices?

A: The primary differences are performance enhancements in the MCP6H04 series. Slew rate increases from 0.55 V/µs to 0.8 V/µs, and gain bandwidth product increases from 730 kHz to 1.2 MHz, providing faster signal response. Supply current decreases from 850 µA to 135 µA across four channels, reducing power consumption. Operating temperature range extends from 0°C to 70°C to -40°C to 125°C. Input bias current increases from 1 pA to 10 pA, and input offset voltage increases from 300 µV to 700 µV. These changes represent performance trade-offs typical between device families.

Q: Does package format affect electrical performance?

A: No. Package format (Tube, Cut Tape & Digi-Reel®, or Tape & Reel) affects only procurement, storage, and assembly line handling. Electrical performance and PCB functionality are identical regardless of packaging format for the same part number base (TLC2264 or MCP6H04).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TLC2264CPWR, MCP6H04-E/ST, and MCP6H04T-E/ST are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original TLC2264CPW specifications. All parts are suitable for applications requiring environmental compliance certification.

Q: Which substitute should be selected for new designs?

A: For new designs, either TLC2264CPWR or MCP6H04 series parts are appropriate. TLC2264CPWR maintains exact electrical specifications of the original obsolete part. MCP6H04 series offers enhanced performance (higher slew rate, greater bandwidth, lower power consumption) and extended temperature range. Selection depends on application requirements and performance priorities. Both are in active production with confirmed inventory availability.
