TLV2404IN Equivalent & Substitute Parts

Part Overview

The TLV2404IN is a general purpose operational amplifier integrated circuit manufactured by Texas Instruments, featuring four independent amplifier circuits in a 14-pin DIP package. This device is classified as Last Time Buy, indicating limited future availability. The TLV2404IN provides rail-to-rail output capability with low power consumption, making it suitable for battery-powered and low-voltage applications. Due to its Last Time Buy status, identifying equivalent substitute parts is essential for design continuity and long-term component sourcing strategy.

Substitute Part Grouping Explanation

Substitution of the TLV2404IN is determined by the following critical parameters: amplifier type (General Purpose), number of circuits (4), output type (Rail-to-Rail), supply voltage range (2.5V to 16V), and package compatibility (14-DIP through-hole mounting). Substitute parts must maintain electrical equivalence within the specified parameter ranges and physical compatibility with the original footprint or acceptable alternative mounting technologies.

The substitute parts identified fall into two categories:

Category 1: Direct Package Equivalent (14-DIP Through-Hole) Parts maintaining identical 14-DIP packaging and through-hole mounting technology.

Category 2: Alternative Package Form (14-SOIC Surface Mount) Parts providing electrical equivalence with different packaging technology, requiring PCB redesign for mounting compatibility.

Engineering Selection Recommendations

TLV2404IDR (Texas Instruments, Active Status)

The TLV2404IDR is the direct electrical equivalent of the TLV2404IN, manufactured by the same supplier with Active product status. This part maintains identical electrical specifications including slew rate, gain bandwidth product, input bias current, and supply voltage range. The primary difference is packaging: TLV2404IDR uses 14-SOIC surface-mount technology versus the 14-DIP through-hole format of the TLV2404IN. Selection of TLV2404IDR requires PCB redesign to accommodate surface-mount footprint but provides superior long-term availability and manufacturing continuity.

LMC6464BIN/NOPB (Texas Instruments, Last Time Buy Status)

The LMC6464BIN/NOPB maintains 14-DIP through-hole packaging identical to the TLV2404IN, eliminating PCB redesign requirements. This CMOS amplifier provides four circuits with rail-to-rail output and operates within the 3V to 15.5V supply range. Performance differences include higher slew rate (0.028V/µs versus 0.0025V/µs), higher gain bandwidth product (50kHz versus 5.5kHz), and significantly higher output current capability (75mA versus 200µA per channel). The LMC6464BIN/NOPB exhibits Last Time Buy status, similar to the TLV2404IN, and does not provide extended availability advantage.

LT1496CN#PBF (Analog Devices Inc., Active Status)

The LT1496CN#PBF is manufactured by Analog Devices Inc. and maintains Active product status, providing superior long-term availability. This general purpose amplifier retains 14-DIP through-hole packaging and four-circuit configuration with rail-to-rail output. The LT1496CN#PBF operates across an extended supply voltage range (2.2V to 36V) and maintains ROHS3 compliance. Performance characteristics differ: lower slew rate (0.001V/µs), lower gain bandwidth product (2.7kHz), higher input bias current (250pA), and higher output current per channel (1.5mA). Operating temperature range is restricted to 0°C to 70°C, narrower than the TLV2404IN specification of -40°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can TLV2404IDR directly replace TLV2404IN without circuit modification?

A: TLV2404IDR provides complete electrical equivalence to TLV2404IN. However, package format differs: TLV2404IDR uses 14-SOIC surface-mount packaging while TLV2404IN uses 14-DIP through-hole packaging. Direct socket substitution is not possible. PCB redesign is required to accommodate the different footprint geometry and mounting technology.

Q: What are the key differences between TLV2404IN and LMC6464BIN/NOPB?

A: Both parts maintain 14-DIP through-hole packaging and four-circuit configuration. Primary differences are amplifier architecture (General Purpose versus CMOS) and performance parameters. LMC6464BIN/NOPB exhibits higher slew rate (0.028V/µs versus 0.0025V/µs), higher gain bandwidth product (50kHz versus 5.5kHz), and substantially higher output current capability (75mA versus 200µA per channel). Supply voltage minimum is 3V for LMC6464BIN/NOPB versus 2.5V for TLV2404IN. Maximum operating temperature is 85°C for LMC6464BIN/NOPB versus 125°C for TLV2404IN.

Q: Is LT1496CN#PBF suitable for applications requiring -40°C operation?

A: No. LT1496CN#PBF specifies operating temperature range of 0°C to 70°C. Applications requiring operation at -40°C must use TLV2404IN, TLV2404IDR, or LMC6464BIN/NOPB, all of which support -40°C minimum operating temperature.

Q: Which substitute part offers the longest product availability?

A: TLV2404IDR and LT1496CN#PBF both carry Active product status, indicating ongoing manufacturing and superior long-term availability compared to Last Time Buy parts. TLV2404IDR is manufactured by Texas Instruments, the original supplier of TLV2404IN, providing supply chain continuity. LT1496CN#PBF is manufactured by Analog Devices Inc., an alternative qualified source.

Q: Can LT1496CN#PBF operate at 16V supply voltage?

A: No. LT1496CN#PBF specifies maximum supply voltage of 36V, which exceeds 16V. However, the minimum supply voltage is 2.2V, lower than TLV2404IN at 2.5V. LT1496CN#PBF is suitable for applications operating within the 2.2V to 16V range, but the extended upper voltage rating (36V) is not required for direct TLV2404IN replacement in 16V maximum applications.

Q: What is the impact of different slew rates on circuit performance?

A: Slew rate determines the maximum rate of output voltage change. TLV2404IN specifies 0.0025V/µs, LMC6464BIN/NOPB specifies 0.028V/µs, and LT1496CN#PBF specifies 0.001V/µs. Applications with fast signal transitions or high-frequency operation may require higher slew rate. Conversely, applications with slow signal requirements tolerate lower slew rate. Substitution must verify that the selected part's slew rate meets circuit bandwidth requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TLV2404IDR, LMC6464BIN/NOPB, and LT1496CN#PBF all carry ROHS3 Compliant status, matching the TLV2404IN compliance level. All parts are REACH Unaffected and classified as EAR99 for export control purposes.
