LMH1251MTX/NOPB

Analog Switches - Special Purpose Overview

The LMH1251MTX/NOPB is a video switch integrated circuit manufactured by Texas Instruments, designed for high-performance signal routing in professional video applications. It operates on a single 5 V power supply and functions within an ambient temperature range of 0°C to +70°C. The device is housed in a 24-pin Thin Shrink Small Outline Package (TSSOP) suitable for surface-mount technology. Key electrical specifications include a 5 V operating voltage and compliance with RoHS standards. This component integrates multiple functionalities into a compact form factor, supporting efficient board space utilization while maintaining signal integrity for analog video transmission.

Analog Switches - Special Purpose Feature Summary

• Integrates YPbPr to RGBHV conversion capabilities alongside switching functions
• Supports 2:1 video switching architecture for flexible signal routing
• Operates efficiently on a single 5 V power supply rail

Analog Switches - Special Purpose Applications

Analog Switches - Special Purpose Procurement Notes

Verify the current lifecycle status before procurement as this specific part number may be discontinued or subject to limited availability. Confirm that the 24-TSSOP package dimensions match your PCB footprint requirements. Ensure the 0°C to +70°C commercial temperature range aligns with your operational environment. Check for alternative revisions or updated components if long-term supply stability is required for production.

Analog Switches - Special Purpose Selection Notes

Select this component when a combined conversion and switching solution is needed for analog video signals. The single 5 V supply requirement simplifies power management compared to dual-supply alternatives. Consider the TSSOP-24 package constraints regarding thermal dissipation and pin pitch during layout. Verify compatibility with source and destination devices regarding signal levels and impedance matching for optimal performance.

Analog Switches - Special Purpose Part Context

This component belongs to the LMH1251 series from Texas Instruments, specifically categorized under Video Switch ICs. It is distinct from general-purpose switches due to its specialized video processing features. The evaluation board LMH1251EVAL/NOPB is available for design verification. It sits within the broader portfolio of Texas Instruments' video interface solutions.

Analog Switches - Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the LMH1251MTX/NNOPB is listed as discontinued, engineers must consult official Texas Instruments resources for potential next-generation replacements or functional equivalents that meet the same YPbPr to RGBHV conversion and 2:1 switching specifications.
