MAX4588CWI+

Analog Switches - Special Purpose Overview

The MAX4588CWI+ is a low-voltage, dual 4-channel multiplexer designed for RF and video signal processing in 50 Ω and 75 Ω systems. It supports frequencies up to 180MHz with a flexible digital interface allowing control via parallel or SPI/MICROWIRE serial ports. The device features a 'T' switch configuration ensuring high off-isolation and low on-resistance of 60Ω max. It operates from single +2.7V to +12V or dual ±2.7V to ±6V supplies. The component is housed in a 28-pin Wide SO package and functions within a temperature range of 0°C to +70°C.

Analog Switches - Special Purpose Feature Summary

• Dual 4-channel multiplexer architecture optimized for RF and video applications
• Flexible digital interface supporting both parallel and serial (SPI/MICROWIRE) control modes
• High-frequency 'T' switch configuration providing excellent isolation and low insertion loss
• Low on-resistance with minimal variation across channels and signal ranges

Analog Switches - Special Purpose Applications

• RF switching in communication systems
• Video signal routing and distribution
• Automatic test equipment signal paths
• High-speed data acquisition systems

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix 'CWI+' corresponds to the required industrial temperature range and package type. Confirm that the Wide SO-28 footprint matches the design constraints. Ensure supply voltage levels align with the specified operational limits to prevent damage. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Analog Switches - Special Purpose Selection Notes

Select this component when dual independent 4-channel multiplexing is required for signals up to 180MHz. Consider the available control interfaces; use the serial mode for pin-saving designs or parallel mode for direct logic control. Evaluate power supply availability, as performance degrades significantly below ±5V operation. Ensure the thermal environment remains within the 0°C to +70°C range for reliable functionality.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4588 family of low-voltage, high-isolation multiplexers. The 'C' suffix indicates the commercial temperature grade (0°C to +70°C), while 'W' denotes the Wide SO package. The '+' suffix typically signifies lead-free and RoHS-compliant manufacturing. Other variants in the series include extended temperature grades and different package options like SSOP and DIP.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes include other MAX4588 variants such as MAX4588EAI+ for extended temperature ranges or MAX4588CPI+ for DIP packaging. Verify pin compatibility and electrical specifications before substitution. Cross-reference with similar dual 4-channel multiplexers from Analog Devices/Maxim Integrated if package changes are permissible.
