MAX4565EWP

Analog Switches - Special Purpose Overview

The MAX4565EWP is a quad, low-voltage, bidirectional RF/video switch manufactured by Analog Devices Inc./Maxim Integrated. It contains four normally open single-pole/single-throw (SPST) switches in a 20-pin Wide SOIC package. The device operates with dual supplies from ±2.7V to ±6V or a single supply between +2.7V and +12V. Key electrical parameters include a maximum on-resistance of 60Ω at ±5V, a -3dB bandwidth of 350MHz, and off-isolation of -83dB at 10MHz. The operating temperature range for the 'E' suffix is -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• High-frequency T-switch architecture ensures superior isolation and crosstalk performance.
• Bidirectional signal paths support rail-to-rail analog signals in either direction.
• TTL and CMOS logic compatibility via dedicated input thresholds.

Analog Switches - Special Purpose Applications

• RF switching
• Video signal routing
• High-speed data acquisition
• Test equipment
• ATE equipment

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure that any additional characters in the part number do not indicate non-standard configurations or restricted materials. Cross-reference the manufacturer's current product status to confirm availability before finalizing procurement plans.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring high bandwidth up to 350MHz and low insertion loss. Consider the 20-pin Wide SOIC package constraints for board layout. Evaluate power supply requirements, as performance degrades significantly when operating away from the optimized ±5V dual-supply configuration.

Analog Switches - Special Purpose Part Context

The MAX4565EWP belongs to the MAX4565/MAX4566/MAX4567 family of low-voltage T-switches. While the MAX4566 offers dual SPST configurations and the MAX4567 provides dual SPDT switches, the MAX4565 specifically integrates four independent SPST channels within a single package.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes within the same family include MAX4565CPP and MAX4565CWP, which share identical functionality but differ in temperature range and package style. Verify pinout compatibility and thermal characteristics when considering alternative packages.
