TLC2264CDR Equivalent & Substitute Parts

Part Overview

The TLC2264CDR is a general-purpose operational amplifier manufactured by Texas Instruments, configured as a quad circuit (4 independent amplifiers) in a 14-SOIC surface mount package. This LinCMOS™ series device operates across a 4.4 V to 16 V supply range with rail-to-rail output capability, making it suitable for low-power analog signal processing applications. The device is currently in Active product status with 15,600 units in stock.

Substitute parts become necessary when the primary device reaches end-of-life status, when alternative packaging formats are required for manufacturing processes, or when enhanced performance characteristics are needed within compatible electrical and mechanical parameters. The three substitute devices listed—LMC6084AIM/NOPB, LMC6084IM/NOPB, and LMC6084IMX/NOPB—maintain the same 14-SOIC package footprint and quad-circuit configuration while offering improved electrical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC2264CDR with the LMC6084 series devices is based on the following compatibility criteria:

Mechanical Compatibility: All substitute parts maintain the identical 14-SOIC (0.154", 3.90mm Width) surface mount package, ensuring direct footprint compatibility on printed circuit boards without layout modifications.

Electrical Configuration: All devices feature four independent operational amplifier circuits in a single package, maintaining the quad-circuit architecture required for applications designed around the TLC2264CDR.

Output Characteristics: All substitute parts provide rail-to-rail output capability, preserving the signal swing performance envelope of the original device.

Supply Voltage Range: The substitute devices operate within overlapping supply voltage specifications. The TLC2264CDR operates from 4.4 V to 16 V, while the LMC6084 series operates from 4.5 V to 15.5 V. This overlap ensures compatibility in applications operating within the 4.5 V to 15.5 V range.

Regulatory Compliance: All substitute parts carry ROHS3 compliance and REACH Unaffected status, matching the environmental and regulatory requirements of the original device.

The LMC6084 series represents an enhanced performance tier within the same functional category, offering improved slew rate, gain bandwidth product, and input bias current specifications while maintaining backward compatibility at the package and circuit level.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Applications: The LMC6084IMX/NOPB is the primary substitute recommendation. This device maintains Active product status, ensuring long-term availability and supply chain stability. It is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly processes. The device carries ROHS3 compliance and MSL 1 rating, matching the environmental specifications of the original TLC2264CDR.

For Extended Temperature Range Requirements: All three LMC6084 variants support an extended operating temperature range of -40°C to 85°C, compared to the TLC2264CDR range of 0°C to 70°C. Applications requiring operation below 0°C or above 70°C must use one of the LMC6084 substitutes.

For Supply Voltage Constrained Applications: Applications operating at supply voltages below 4.5 V require the TLC2264CDR, as the LMC6084 series specifies a minimum supply voltage of 4.5 V. The TLC2264CDR supports operation down to 4.4 V.

For Last-Time-Buy Scenarios: The LMC6084IM/NOPB carries Last Time Buy status, indicating limited future availability. This device should be selected only when existing inventory commitments or specific packaging requirements (Tube packaging) necessitate its use. For new designs, the LMC6084IMX/NOPB is preferred.

For National Semiconductor Source Requirements: The LMC6084AIM/NOPB is manufactured by National Semiconductor and supplied in Bulk packaging. This variant is suitable for applications with specific supplier diversification requirements or when National Semiconductor sourcing is mandated by procurement specifications.

Frequently Asked Questions (FAQ)

Q: Can the LMC6084 series devices be used as direct pin-for-pin replacements for the TLC2264CDR?

A: Yes. All three LMC6084 variants share the identical 14-SOIC package footprint and pinout configuration with the TLC2264CDR. No circuit board modifications or pin remapping are required for substitution.

Q: What are the key electrical differences between the TLC2264CDR and the LMC6084 series?

A: The LMC6084 series offers superior performance in three primary areas: slew rate (1.5 V/µs versus 0.55 V/µs), gain bandwidth product (1.3 MHz versus 730 kHz), and input bias current (0.01 pA versus 1 pA). These improvements result in faster signal response and lower input current requirements. However, the LMC6084 series draws higher supply current (2.2 mA per channel versus 850 µA per channel for the TLC2264CDR).

Q: Are there supply voltage compatibility issues when substituting the TLC2264CDR with LMC6084 devices?

A: The LMC6084 series specifies a minimum supply voltage of 4.5 V, while the TLC2264CDR operates from 4.4 V. Applications operating at exactly 4.4 V cannot use the LMC6084 substitutes. All other applications within the 4.5 V to 15.5 V overlap range are compatible.

Q: What is the difference between the three LMC6084 part numbers?

A: The three variants differ in manufacturer source and packaging format. LMC6084AIM/NOPB is manufactured by National Semiconductor and supplied in Bulk packaging. LMC6084IM/NOPB is manufactured by Texas Instruments in Tube packaging and carries Last Time Buy status. LMC6084IMX/NOPB is manufactured by Texas Instruments in Tape & Reel packaging and maintains Active product status. All three share identical electrical specifications.

Q: Which LMC6084 variant should be selected for new product designs?

A: The LMC6084IMX/NOPB is the recommended choice for new designs. It maintains Active product status, ensuring long-term availability, and is supplied in Tape & Reel packaging, which is standard for automated surface mount assembly processes.

Q: Does the extended operating temperature range of the LMC6084 series affect circuit performance?

A: The extended temperature range (-40°C to 85°C for LMC6084 versus 0°C to 70°C for TLC2264CDR) indicates the device is qualified for operation across a wider temperature envelope. Applications operating within the original TLC2264CDR temperature range experience identical performance characteristics.

Q: Are there any compliance or regulatory differences between the TLC2264CDR and LMC6084 substitutes?

A: The TLC2264CDR, LMC6084IM/NOPB, and LMC6084IMX/NOPB all carry ROHS3 compliance and REACH Unaffected status. The LMC6084AIM/NOPB does not specify these certifications in the provided data. For applications with mandatory ROHS3 or REACH compliance requirements, use LMC6084IM/NOPB or LMC6084IMX/NOPB.

Q: What is the impact of higher supply current consumption in the LMC6084 series on power supply design?

A: The LMC6084 series draws 2.2 mA per channel (8.8 mA total for four channels) compared to 850 µA per channel (3.4 mA total) for the TLC2264CDR. Power supply designs must account for this 2.6× increase in current draw. Decoupling capacitor sizing and power distribution network design may require adjustment.

Q: Can the TLC2264CDR and LMC6084 devices be mixed in the same circuit board design?

A: Yes. Both device families can coexist on the same circuit board. However, each device must be independently evaluated against its specific electrical specifications and operating conditions. Mixed-device designs should document the rationale for device selection at each location.
