LMC6464AIN Equivalent & Substitute Parts

Part Overview

The LMC6464AIN is a CMOS quad operational amplifier manufactured by Texas Instruments, housed in a 14-pin DIP package. This device features rail-to-rail output capability and is designed for low-power analog signal processing applications. The part is classified as Obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain compatibility across electrical performance, package form factor, and supply voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LMC6464AIN is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of circuits: 4 channels required
• Package form factor: 14-DIP through-hole mounting
• Output configuration: Rail-to-rail output capability
• Supply voltage range: Minimum 3 V, maximum 15.5 V overlap required
• Amplifier topology: CMOS or general-purpose operational amplifier

Secondary Compatibility Criteria:

• Slew rate: 0.028 V/µs or greater
• Gain bandwidth product: 50 kHz or greater
• Input bias current: 0.15 pA or lower
• Input offset voltage: 250 µV or lower
• Output current per channel: 75 mA or greater

The LMC6464BIN/NOPB maintains identical electrical specifications and package configuration, qualifying as a direct equivalent. The TLV2404IN provides functional substitution with relaxed performance in certain parameters (lower slew rate and gain bandwidth product) but operates within the required supply voltage range and maintains rail-to-rail output capability.

Parameter Comparison

Engineering Selection Recommendations

LMC6464BIN/NOPB is the primary substitute for LMC6464AIN. Both devices share identical electrical specifications, package configuration, and mounting type. The LMC6464BIN/NOPB carries Last Time Buy status, indicating limited future availability. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

TLV2404IN serves as a secondary substitute when LMC6464BIN/NOPB is unavailable. This device maintains the required 4-channel configuration, 14-DIP package, and rail-to-rail output capability. However, the TLV2404IN exhibits reduced performance in slew rate (0.0025 V/µs versus 0.028 V/µs) and gain bandwidth product (5.5 kHz versus 50 kHz). The TLV2404IN also demonstrates higher input bias current (100 pA versus 0.15 pA) and higher supply current consumption (900 nA versus 90 µA per channel). The TLV2404IN supports an extended operating temperature range (-40°C to 125°C) and lower minimum supply voltage (2.5 V). Selection of TLV2404IN requires verification that application bandwidth and slew rate requirements do not exceed 5.5 kHz and 0.0025 V/µs respectively.

Both substitute parts are ROHS3 compliant and REACH unaffected, maintaining compliance with current environmental and regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can LMC6464BIN/NOPB directly replace LMC6464AIN in existing designs?

A: Yes. The LMC6464BIN/NOPB is electrically and mechanically identical to the LMC6464AIN. Both devices feature identical slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, supply voltage range, and package configuration. No circuit modifications are required.

Q: What are the key differences between LMC6464AIN and TLV2404IN?

A: The primary differences are slew rate (0.028 V/µs versus 0.0025 V/µs), gain bandwidth product (50 kHz versus 5.5 kHz), input bias current (0.15 pA versus 100 pA), input offset voltage (250 µV versus 390 µV), and supply current consumption (90 µA versus 900 nA per channel). The TLV2404IN supports a lower minimum supply voltage (2.5 V) and extended operating temperature range (-40°C to 125°C). Applications requiring bandwidth above 5.5 kHz or slew rates above 0.0025 V/µs cannot use TLV2404IN.

Q: Are all substitute parts available in the same packaging?

A: Yes. LMC6464AIN, LMC6464BIN/NOPB, and TLV2404IN are all supplied in 14-DIP (0.300", 7.62mm) through-hole packages. Pin configuration and footprint are identical across all three devices.

Q: What is the product status of available substitutes?

A: LMC6464BIN/NOPB carries Last Time Buy status, indicating limited future availability. TLV2404IN also carries Last Time Buy status. Both parts should be procured with consideration for long-term supply constraints.

Q: Do all substitute parts meet current compliance requirements?

A: Yes. LMC6464AIN, LMC6464BIN/NOPB, and TLV2404IN are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Which substitute is recommended for new designs?

A: LMC6464BIN/NOPB is recommended for new designs requiring direct electrical equivalence to LMC6464AIN. TLV2404IN is suitable only for applications where reduced bandwidth (5.5 kHz maximum) and slew rate (0.0025 V/µs maximum) are acceptable.
