Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM6584MTX is determined by the following critical parameters:

Functional Requirements:

• Four-channel amplifier configuration
• Rail-to-rail output capability
• General-purpose amplification application class
• Surface mount technology

Electrical Performance Criteria:

• Bandwidth capability (minimum 10 MHz acceptable for general-purpose applications)
• Slew rate (minimum 10V/µs acceptable)
• Output current per channel (minimum 41 mA acceptable)
• Supply voltage range compatibility (3.5V to 12V minimum span)

Physical and Compliance Constraints:

• Package type: 14-TSSOP or 14-SOIC (both 14-pin surface mount packages with compatible pinouts for general-purpose amplifier applications)
• RoHS3 compliance preferred for new designs
• MSL rating of 1 or 3 acceptable for standard handling

Substitute parts are grouped into two categories:

Category 1: Direct Package Match (14-TSSOP)

• LM6584MTX/NOPB (Texas Instruments, Active status, identical electrical specifications, improved RoHS compliance)
• MCP6H94T-E/ST (Microchip Technology, Active status, compatible electrical performance, same package)

Category 2: Alternative Package Match (14-SOIC)

• MCP6H94-E/SL (Microchip Technology, Active status, Tube packaging)
• MCP6H94T-E/SL (Microchip Technology, Active status, Tape & Reel packaging)

All substitute parts maintain the four-channel configuration, rail-to-rail output, and general-purpose amplifier classification required for functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: LM6584MTX/NOPB

The LM6584MTX/NOPB is the direct equivalent substitute. This part maintains identical electrical specifications to the original LM6584MTX while offering active product status and ROHS3 compliance. The part is available in Tape & Reel packaging suitable for automated assembly. Current inventory of 2238 pieces supports production requirements. This substitute requires no circuit redesign and provides pin-for-pin compatibility in the 14-TSSOP package.

Secondary Recommendation: MCP6H94T-E/ST

The MCP6H94T-E/ST from Microchip Technology provides functional equivalence with active product status and ROHS3 compliance. This part maintains the 14-TSSOP package format and four-channel rail-to-rail configuration. Electrical performance specifications (10V/µs slew rate, 10 MHz gain bandwidth product, 41 mA output current per channel) are within acceptable ranges for general-purpose amplification applications. The part is available in Tape & Reel packaging with 969 pieces in current inventory. MSL rating of 1 (Unlimited) supports standard handling procedures.

Alternative Recommendation: MCP6H94-E/SL or MCP6H94T-E/SL

The MCP6H94-E/SL and MCP6H94T-E/SL provide functional equivalence with the trade-off of package format change from 14-TSSOP to 14-SOIC. Both parts offer active product status and ROHS3 compliance. The MCP6H94-E/SL is available in Tube packaging (3,000,200 pieces inventory), while MCP6H94T-E/SL is available in Tape & Reel packaging (2,869 pieces inventory). Circuit board layout modification is required to accommodate the 14-SOIC package footprint. These options are suitable when PCB redesign is acceptable and when leveraging high inventory availability is advantageous.

Compliance Considerations:

All recommended substitutes achieve ROHS3 compliance, addressing regulatory requirements for new designs. The original LM6584MTX is RoHS non-compliant; substitution with compliant alternatives supports environmental and regulatory standards. Moisture sensitivity levels are acceptable for standard manufacturing and storage conditions across all recommended parts.

Frequently Asked Questions (FAQ)

Q1: Can the LM6584MTX/NOPB be used as a direct replacement for the LM6584MTX?

A: Yes. The LM6584MTX/NOPB is a direct substitute with identical electrical specifications, the same 14-TSSOP package, and pin-for-pin compatibility. The primary difference is improved product status (Active vs. Obsolete) and ROHS3 compliance. No circuit modifications are required.

Q2: What are the key differences between the LM6584MTX and the MCP6H94T-E/ST?

A: Both parts are four-channel, rail-to-rail general-purpose amplifiers in 14-TSSOP packages. The LM6584MTX offers higher bandwidth (24 MHz vs. 10 MHz) and higher slew rate (15V/µs vs. 10V/µs). The MCP6H94T-E/ST offers lower supply current (2mA total vs. 780µA per channel) and lower output current per channel (41 mA vs. 75 mA). The MCP6H94T-E/ST is active and ROHS3 compliant. Selection depends on whether the higher performance specifications of the LM6584MTX are required for the application.

Q3: Why would I choose a 14-SOIC package substitute over the 14-TSSOP package?

A: The 14-SOIC package alternatives (MCP6H94-E/SL and MCP6H94T-E/SL) offer significantly higher inventory availability, particularly the MCP6H94-E/SL with over 3 million pieces in stock. If PCB redesign is feasible, these options provide superior supply chain security and potentially lower cost. The electrical performance and functional capability remain equivalent for general-purpose amplification applications.

Q4: Are there any supply voltage compatibility issues when substituting with Microchip parts?

A: The Microchip MCP6H94 series supports a supply voltage span of 3.5V to 12V, which is narrower than the LM6584MTX range of 5V to 13V (single supply) or ±2.5V to ±6.5V (dual supply). Applications operating at supply voltages above 12V or below 3.5V require the original LM6584MTX or LM6584MTX/NOPB. For standard applications within the 3.5V to 12V range, Microchip substitutes are fully compatible.

Q5: What is the impact of lower output current in the MCP6H94 series?

A: The MCP6H94 series provides 41 mA output current per channel compared to 75 mA for the LM6584MTX. Applications requiring output currents exceeding 41 mA per channel must use the LM6584MTX or LM6584MTX/NOPB. For general-purpose signal conditioning and buffering applications, the 41 mA specification is typically sufficient.

Q6: Does the MSL rating difference between MCP6H94T-E/SL (MSL 3) and other parts affect usability?

A: The MCP6H94T-E/SL has an MSL rating of 3 (168 hours), requiring moisture bake-out procedures if the part is exposed to ambient humidity for extended periods before reflow soldering. Other recommended substitutes have MSL 1 (Unlimited), requiring no special moisture handling. For standard manufacturing environments with controlled humidity and immediate assembly, the MSL 3 rating presents no practical limitation. High-volume or extended storage applications should prioritize MSL 1 rated parts.

Q7: Can I use the MCP6H94 series in applications requiring 24 MHz bandwidth?

A: No. The MCP6H94 series is specified with 10 MHz gain bandwidth product, which is insufficient for applications requiring 24 MHz bandwidth. The LM6584MTX and LM6584MTX/NOPB are the only suitable options for high-bandwidth applications. Microchip substitutes are appropriate only for applications where 10 MHz bandwidth is adequate.

Q8: What packaging format should I select for automated assembly?

A: Tape & Reel (TR) packaging is standard for automated pick-and-place assembly. Recommended parts in Tape & Reel format include LM6584MTX/NOPB, MCP6H94T-E/ST, and MCP6H94T-E/SL. Tube packaging (MCP6H94-E/SL) requires manual handling and is suitable for lower-volume or manual assembly processes.
