MAX4456CQH+D

Analog Switches - Special Purpose Overview

The MAX4456CQH+D is an 8x8 video crosspoint switch in a 44-pin PLCC package, operating from 0°C to +70°C. It features dual supplies of ±4.5V to ±5.5V and a 65MHz -3dB bandwidth. The device includes eight internal buffers with a 250V/µs slew rate, capable of driving 400Ω loads at 2.6Vp-p. Key electrical specifications include 80dB all-channel off-isolation and 70dB single-channel crosstalk at 5MHz.

Analog Switches - Special Purpose Feature Summary

• Supports serial or parallel digital interfaces for flexible control integration
• Provides three-state output capability with power-saving disable feature
• Enables expansion into larger switch matrices through parallel device connection

Analog Switches - Special Purpose Applications

• High-speed signal routing systems
• Video-on-demand infrastructure
• Video test equipment
• Video conferencing platforms
• Security surveillance systems

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix CQH+D against official documentation to confirm the 44-pin PLCC package and commercial temperature range. Ensure compatibility with existing board layouts and supply voltage requirements before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when an 8x8 matrix configuration is required. Compare against the MAX4359 (4x4) or MAX4360 (8x4) if fewer channels are sufficient. Consider the MAX456 if industrial temperature ranges (-40°C to +85°C) are necessary instead of the commercial grade.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4359/MAX4360/MAX4456 family of low-cost video crosspoint switches. These devices utilize T-switch matrices to route video signals between inputs and buffered outputs, reducing system component count and design time compared to discrete solutions.

Analog Switches - Special Purpose Replacement Considerations

The MAX4456EQH serves as a direct pin-compatible replacement offering an extended industrial temperature range of -40°C to +85°C. Verify that the thermal requirements of the application align with the selected variant's operational limits.
