Key Parameters

Substitute Part Grouping Explanation

Substitution of the HA4314BCBZ is determined by the following critical parameters:

• Multiplexer Configuration: 4:1 channel architecture
• Bandwidth Performance: 400MHz -3dB bandwidth minimum
• Supply Voltage: Dual supply operation (±4.5V ~ 5.5V)
• Package Compatibility: 14-SOIC surface mount form factor
• Interface Category: Video switching and multiplexing functionality

The LMH6574MA/NOPB from Texas Instruments satisfies these core functional requirements as a 4:1 high-speed video multiplexer with equivalent channel architecture and bandwidth performance.

Parameter Comparison

Engineering Selection Recommendations

The LMH6574MA/NOPB is the identified substitute for the obsolete HA4314BCBZ based on functional equivalence in 4:1 multiplexer architecture and video interface classification. The substitute part carries Active product status, ensuring long-term availability and supply chain continuity.

Both components maintain identical export classification (EAR99) and tariff codes (HTSUS 8542.39.0001), with REACH compliance confirmed for both devices. The substitute part demonstrates improved moisture sensitivity characteristics (MSL 1 versus MSL 2), providing enhanced reliability in storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: What makes the LMH6574MA/NOPB a suitable substitute for the HA4314BCBZ?

A: Both devices function as 4:1 video multiplexers within the Interface category, providing equivalent channel architecture for video switching applications. The substitute part is currently in Active production status, addressing the obsolescence of the original component.

Q: Are there package compatibility considerations between these parts?

A: Package information for the LMH6574MA/NOPB is not provided in the available technical data. Physical package verification is required before PCB layout finalization to confirm mechanical compatibility with existing designs.

Q: What are the compliance differences between the two parts?

A: Both parts maintain REACH Unaffected status and identical export classifications (EAR99). The substitute part offers superior moisture sensitivity performance (MSL 1 with unlimited shelf life versus MSL 2 with 1-year shelf life).

Q: Is supply availability a factor in this substitution?

A: Yes. The HA4314BCBZ is classified as Obsolete with limited remaining inventory. The LMH6574MA/NOPB maintains Active status with established supply channels, ensuring component availability for current and future production requirements.

Q: What parameters should be verified before implementing this substitute?

A: Electrical parameters including bandwidth performance, supply voltage ranges, and operating temperature specifications should be confirmed against application requirements. Physical package dimensions and pinout compatibility must be validated for PCB integration.
