MAX456CQH+

Overview

The MAX456CQH+ is an 8x8 video crosspoint switch manufactured by Analog Devices Inc./Maxim Integrated. It integrates 64 SPST switches to form a matrix for routing video signals. The device operates on a single 5V supply and supports signal levels up to 1Vp-p. Key electrical parameters include a bandwidth of 100MHz, an on-resistance of 75 Ohms maximum, and switching times of 200ns (on) and 100ns (off). It features low charge injection and high channel-to-channel isolation, suitable for professional video applications.

Feature Summary

• Integrates an 8x8 matrix of single-pole single-throw switches for flexible signal routing
• Supports bidirectional analog signal transmission with low distortion
• Features fast switching speeds and low charge injection for high-fidelity video
• Operates from a single 5V power supply

Applications

• Video distribution systems
• Video surveillance matrices
• Professional audio/video switching equipment
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'CQH+' against the official datasheet to confirm package type and temperature range. Confirm availability status as this component may be subject to lifecycle changes or limited stock. Ensure compatibility with existing PCB footprints for the QFP package before procurement.

Selection Notes

Select this component when an 8x8 switching matrix is required for video signals. Compare on-resistance and bandwidth requirements against other Maxim video switches. Consider the single-supply operation and package constraints relative to system design needs.

Part Context

This part belongs to the MAX456 family of video crosspoint switches. It is designed for applications requiring multiple video inputs to be routed to multiple outputs. The device simplifies system design by integrating the switching matrix into a single IC, reducing board space and component count compared to discrete solutions.

Replacement Considerations

Check for direct pin-compatible replacements within the MAX456 series. Verify if newer generations offer improved specifications such as higher bandwidth or lower power consumption while maintaining the same interface.
