MAX4359EWG

Analog Switches - Special Purpose Overview

The MAX4359EWG+ is a low-cost video crosspoint switch featuring a 4x4 T-switch matrix housed in a 24-pin SOIC package. It operates on dual supplies ranging from ±4.5V to ±5.5V, with a typical supply current of 37mA when all buffers are active. The device provides a small-signal -3dB bandwidth of 65MHz and an output-buffer slew rate of 250V/µs. Key electrical specifications include 80dB all-channel off-isolation and 70dB single-channel crosstalk at 5MHz. It supports both serial and parallel digital interfaces for routing any input channel to any buffered output.

Analog Switches - Special Purpose Feature Summary

• Contains a 4x4 matrix of T-switches connecting four video inputs to four buffered outputs.
• Features internal high-speed unity-gain amplifiers capable of driving 400Ω loads.
• Supports three-state output capability and power-saving disable features.
• Includes straight-through pinouts to simplify circuit layout.

Analog Switches - Special Purpose Applications

• High-Speed Signal Routing
• Video-On-Demand Systems
• Video Test Equipment
• Video Conferencing
• Security Systems

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'EWG+' against the manufacturer's official datasheet to confirm the 24-pin SOIC package and industrial temperature range (-40°C to +85°C). Ensure that the ordering information matches the exact component designation required for the design, as suffix variations may indicate different packaging or environmental ratings.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring a compact 4x4 video switching solution. It serves as a low-cost alternative to larger matrices like the MAX4456. Consider the 65MHz bandwidth and 250V/µs slew rate for standard definition video signals. Verify interface compatibility with either serial or parallel control logic before finalizing the design.

Analog Switches - Special Purpose Part Context

The MAX4359 belongs to a family of low-cost video crosspoint switches that includes the MAX4360 (8x4) and MAX4456 (8x8). These devices share similar functional architectures but differ in matrix size and pin counts. The MAX4359 specifically replaces the 8x8 matrix found in the MAX4456 with a smaller 4x4 configuration, offering a reduced footprint for simpler routing tasks.

Analog Switches - Special Purpose Replacement Considerations

The MAX4456 is a pin-for-pin compatible alternative within the same product family, though it features an 8x8 matrix instead of 4x4. Designers should verify that the additional channels do not interfere with board space constraints or that the unused pins can be properly managed in the new application.
