LM6584MA Equivalent & Substitute Parts

Part Overview

The LM6584MA is a general-purpose video amplifier integrated circuit manufactured by Texas Instruments, housed in a 14-SOIC surface mount package. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement continuity. The LM6584MA provides four independent amplifier circuits with rail-to-rail output capability, suitable for general-purpose amplification applications requiring moderate bandwidth and slew rate performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM6584MA is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Package compatibility: 14-SOIC (0.154", 3.90mm Width) surface mount package
• Number of circuits: 4 independent amplifier channels
• Output type: Rail-to-Rail configuration
• Mounting type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Parameters:

• Supply voltage range must encompass or match the original specification
• Output current per channel must meet or exceed 75 mA minimum
• Slew rate and bandwidth performance determine application suitability

Substitution Categories:

Direct Equivalent: LM6584MA/NOPB represents the active production variant of the base LM6584 design. This part maintains identical electrical specifications and package configuration while offering active product status and RoHS3 compliance.

Manufacturer-Recommended Substitute: MAX4395ESD+T is designated as the manufacturer-recommended alternative. While this part shares the 14-SOIC package and four-circuit configuration, it introduces enhanced electrical performance characteristics (85 MHz bandwidth, 500 V/µs slew rate) and operates within a different supply voltage range (4.5V ~ 11V, ±2.25V ~ 5.5V). This part is suitable for applications where the LM6584MA performance envelope is insufficient or where RoHS3 compliance is mandatory.

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Performance-Matched):

Select LM6584MA/NOPB when procurement of the original LM6584MA is not feasible. This part is the active production equivalent of the base LM6584 design and maintains identical electrical specifications and package pinout. The LM6584MA/NOPB is RoHS3 compliant and carries active product status, making it suitable for new designs and ongoing production support. No circuit modifications are required for this substitution.

For Enhanced Performance Applications:

Select MAX4395ESD+T when the application requires improved bandwidth (85 MHz versus 24 MHz) or faster slew rate (500 V/µs versus 15 V/µs) performance. This part is RoHS3 compliant and carries active product status. The MAX4395ESD+T operates within a narrower supply voltage range (4.5V ~ 11V, ±2.25V ~ 5.5V) compared to the LM6584MA (5V ~ 13V, ±2.5V ~ 6.5V). Circuit design verification is required to confirm supply voltage compatibility and to validate that the enhanced performance characteristics do not introduce stability or thermal management concerns in the target application.

Compliance Considerations:

Both substitute parts are RoHS3 compliant, addressing regulatory requirements that may be associated with the obsolete, non-compliant LM6584MA. Both substitute parts maintain MSL 1 (Unlimited) moisture sensitivity classification, consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can LM6584MA/NOPB be used as a direct drop-in replacement for LM6584MA?

A: Yes. LM6584MA/NOPB is the active production variant of the LM6584 base design. It maintains identical electrical specifications, pinout, and 14-SOIC package configuration. No circuit modifications are required. The primary difference is product status (active versus obsolete) and RoHS compliance (RoHS3 compliant versus non-compliant).

Q: What are the key differences between LM6584MA and MAX4395ESD+T?

A: Both parts share the 14-SOIC package, four-circuit configuration, and rail-to-rail output type. The MAX4395ESD+T provides significantly higher bandwidth (85 MHz versus 24 MHz) and slew rate (500 V/µs versus 15 V/µs). The MAX4395ESD+T operates at higher supply current (6 mA versus 780 µA) and within a narrower supply voltage range (4.5V ~ 11V, ±2.25V ~ 5.5V versus 5V ~ 13V, ±2.5V ~ 6.5V). Circuit design verification is required before substitution.

Q: Is the MAX4395ESD+T suitable for all LM6584MA applications?

A: The MAX4395ESD+T is suitable only for applications where the supply voltage range (4.5V ~ 11V, ±2.25V ~ 5.5V) is compatible with the circuit design. The enhanced bandwidth and slew rate may introduce stability or noise considerations in circuits originally designed for the LM6584MA performance envelope. Circuit simulation and testing are required to confirm suitability.

Q: Are both substitute parts available in the same packaging format?

A: LM6584MA/NOPB is available in Tube packaging. MAX4395ESD+T is available in Tape & Reel (TR) packaging. Both parts use the 14-SOIC (0.154", 3.90mm Width) surface mount package case. Packaging format selection depends on procurement and assembly process requirements.

Q: What is the moisture sensitivity level for the substitute parts?

A: Both LM6584MA/NOPB and MAX4395ESD+T carry MSL 1 (Unlimited) moisture sensitivity classification, identical to the original LM6584MA. No additional moisture control measures are required during storage or handling.

Q: Are there any RoHS compliance differences between the substitute parts?

A: LM6584MA/NOPB and MAX4395ESD+T are both RoHS3 compliant. The original LM6584MA is RoHS non-compliant. If RoHS compliance is a design requirement, either substitute part is acceptable.
