LMH6570MAX

Analog Switches - Special Purpose Overview

The LMH6570MAX is a high-speed video multiplexer manufactured by National Semiconductor, now part of Texas Instruments. It functions as a 2:1 multiplexer designed for professional video applications. The device operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package. Key electrical characteristics include a bandwidth of 300 MHz at unity gain (Vout = 0.5 Vpp) and a settling time of 10 ns to 0.1% for a 2 V step. It features low differential gain of 0.02% and differential phase of 0.02°, ensuring high signal fidelity in video transmission systems.

Analog Switches - Special Purpose Feature Summary

• High-speed video switching capability with wide bandwidth for professional signal integrity
• Integrated on-chip feedback resistors simplify printed circuit board layout
• Low distortion and minimal differential gain/phase errors preserve video quality

Analog Switches - Special Purpose Applications

• Professional video routing and switching matrices
• Video distribution amplifiers
• Test and measurement equipment requiring high-fidelity signal switching

Analog Switches - Special Purpose Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required package and temperature grade. Confirm RoHS compliance status through official datasheets or authorized distributors, as legacy parts may have varying environmental certifications depending on production batch.

Analog Switches - Special Purpose Selection Notes

Select this component when a single-channel, high-bandwidth video switch is required. Compare against other LMH series devices if higher channel counts or different power constraints are needed. Verify that the 8-pin SOIC package fits the available PCB footprint and that the operating temperature range meets the system's environmental requirements.

Analog Switches - Special Purpose Part Context

This component belongs to the LMH6570 family of high-speed video multiplexers. Variants such as LMH6570MA/NOPB share similar functional specifications but may differ in packaging or lead-free certification. The MAX suffix typically denotes the industrial temperature range and SOIC package style within the product line.

Analog Switches - Special Purpose Replacement Considerations

LMH6570MA/NOPB is a documented equivalent variant within the same family, offering identical functionality with potential differences in lead-free compliance or specific package tolerances.
