LMH6572MQ Equivalent & Substitute Parts
Part Overview
The LMH6572MQ is a video multiplexer IC designed for 2:1 switching of 3-channel video signals in RGB applications. Manufactured by Texas Instruments, this 16-SSOP surface mount device operates across supply voltage ranges of 6V to 12V (single supply) or ±3V to 6V (dual supply), with a -3dB bandwidth of 350MHz suitable for video signal routing.
The LMH6572MQ carries an Obsolete product status. Locating equivalent or substitute components is necessary to maintain design continuity, ensure supply chain reliability, and access devices with active manufacturing support and current compliance certifications.

Substitute Part Grouping Explanation
Substitution of the LMH6572MQ is determined by strict equivalence across the following electrical and mechanical parameters:
- 2:1 multiplexer/demultiplexer circuit topology
- 3-channel video signal switching capability
- 350MHz -3dB bandwidth for RGB video applications
- 6V to 12V single supply or ±3V to 6V dual supply operation
- -40°C to 85°C operating temperature range
- 16-SSOP surface mount package with 0.154" (3.90mm) width
The LMH6572MQ/NOPB is a direct substitute manufactured by Texas Instruments under the same base product number (LMH6572) with identical electrical specifications and package configuration. The primary distinction is product status and compliance certification level.

Engineering Selection Recommendations
The LMH6572MQ/NOPB is the direct functional equivalent of the LMH6572MQ. Both devices share identical electrical performance specifications and package geometry, ensuring pin-for-pin compatibility in existing circuit designs.
Selection between these parts should be based on the following criteria:
For new designs or redesigns, the LMH6572MQ/NOPB is the preferred choice due to its Active product status, ensuring continued manufacturing availability and supply chain support. The LMH6572MQ/NOPB also carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for component procurement in most jurisdictions.
For legacy system maintenance or repair applications where the original LMH6572MQ is specified, the LMH6572MQ/NOPB provides a direct replacement without circuit modification, as all electrical and mechanical parameters remain identical.
Frequently Asked Questions (FAQ)
Q: Can the LMH6572MQ/NOPB be used as a direct replacement for the LMH6572MQ?
A: Yes. Both devices are manufactured by Texas Instruments under the same base product number and share identical electrical specifications, bandwidth performance, supply voltage ranges, operating temperature range, and 16-SSOP package configuration. Pin-for-pin compatibility is maintained.
Q: What is the significance of the "/NOPB" suffix in the LMH6572MQ/NOPB part number?
A: The "/NOPB" suffix indicates the device is supplied in Tube packaging and carries current RoHS3 compliance certification. The electrical and functional specifications remain identical to the base LMH6572MQ designation.
Q: Why is the LMH6572MQ listed as Obsolete?
A: Obsolete status indicates Texas Instruments has discontinued active manufacturing of this specific part number variant. The LMH6572MQ/NOPB remains in active production and is the recommended source for new component procurement.
Q: Are there any circuit design considerations when substituting the LMH6572MQ with the LMH6572MQ/NOPB?
A: No circuit design modifications are required. Both devices operate identically across the specified voltage supply ranges (6V to 12V single supply or ±3V to 6V dual supply), maintain the same 350MHz -3dB bandwidth for RGB video applications, and are housed in the identical 16-SSOP surface mount package.
Q: What is the moisture sensitivity level for these devices?
A: Both the LMH6572MQ and LMH6572MQ/NOPB carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
