LMH6570MA Video Multiplexer IC Equivalent & Substitute Parts

Part Overview

The LMH6570MA is a video switch integrated circuit designed for single-channel 2:1 multiplexer/demultiplexer applications. This buffered video interface component operates across supply voltage ranges of 6V to 12V (single supply) or ±3V to 6V (dual supply), with a -3dB bandwidth of 500MHz. The device is housed in an 8-SOIC surface mount package.

The LMH6570MA carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and access components with active manufacturing support and current compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LMH6570MA is determined by the following critical parameters:

• Multiplexer/Demultiplexer circuit configuration (2:1)
• Single channel architecture
• Supply voltage compatibility (6V ~ 12V single supply; ±3V ~ 6V dual supply)
• Bandwidth specification (500MHz -3dB)
• Buffered output feature
• 8-SOIC surface mount package footprint
• Operating temperature range (-40°C ~ 85°C)

Parts meeting all these electrical and mechanical specifications are classified as direct substitutes. The LMH6570MA/NOPB variant satisfies all substitution criteria while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The LMH6570MA/NOPB is the direct substitute for the obsolete LMH6570MA. Both parts share identical electrical specifications and mechanical packaging. The LMH6570MA/NOPB offers two significant advantages:

• Active product status ensures ongoing manufacturing support and availability
• ROHS3 compliance meets current environmental and regulatory requirements, whereas the original LMH6570MA is RoHS non-compliant

For new designs or component replenishment, the LMH6570MA/NOPB is the appropriate selection. Pin-to-pin compatibility and functional equivalence are confirmed across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the LMH6570MA/NOPB be used as a direct replacement for the LMH6570MA?

A: Yes. Both parts are electrically and mechanically identical. The LMH6570MA/NOPB is the active production variant with current compliance certifications.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" designation indicates lead-free, RoHS3 compliant manufacturing. This variant meets modern environmental standards while maintaining full functional compatibility.

Q: Are there any package differences between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. The LMH6570MA/NOPB is supplied in tube packaging, whereas the original part packaging is not specified.

Q: What supply voltage configurations does this IC support?

A: The LMH6570MA and LMH6570MA/NOPB support both single supply (6V ~ 12V) and dual supply (±3V ~ 6V) configurations.

Q: Is the -3dB bandwidth specification identical between both parts?

A: Yes. Both parts maintain 500MHz -3dB bandwidth performance.

Q: What is the operating temperature range?

A: Both parts operate across -40°C to 85°C (TA).
