MAX4565EWP+

Analog Switches - Special Purpose Overview

The MAX4565EWP+ is a quad, low-voltage, bidirectional RF/video switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features four normally open single-pole/single-throw (SPST) switches in a 20-pin Wide SOIC package. The device operates with dual power supplies ranging 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, off isolation of -83dB at 10MHz, and channel-to-channel crosstalk of -92dB at 10MHz. Turn-on time is typically 150ns and turn-off time is typically 100ns under ±5V conditions.

Analog Switches - Special Purpose Feature Summary

• High-frequency T-switch architecture ensures excellent high-frequency off isolation and crosstalk performance.
• Bidirectional signal paths handle rail-to-rail analog signals in either direction within specified voltage limits.
• TTL and CMOS logic compatibility is maintained through specific input thresholds when using ±5V or single +5V supplies.
• Low power consumption with minimal supply current requirements for efficient system operation.

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 exact ordering suffix against official documentation to confirm package type and temperature range. The E suffix indicates an extended temperature range of -40°C to +85°C. Ensure the supplier provides valid RoHS compliance certificates as required by project specifications. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit components.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring high bandwidth up to 350MHz and low crosstalk in video or RF systems. Consider the 60Ω maximum on-resistance when designing for low attenuation in 50Ω or 75Ω systems. Verify that the supply voltage range matches the available power rails, noting that performance degrades significantly below the optimized ±5V operating point.

Analog Switches - Special Purpose Part Context

This device belongs to the MAX4565/MAX4566/MAX4567 family of low-voltage T-switches. While the MAX4565 contains four SPST switches, the MAX4566 offers two dual SPST switches and the MAX4567 provides two SPDT switches. All variants share similar electrical characteristics and are designed for switching RF and video signals in 50Ω and 75Ω systems.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes within the same family include MAX4565CPP and MAX4565CWP for commercial temperature ranges. For surface-mount alternatives, consider MAX4565EEE+ or MAX4565ESE+. Verify pinout compatibility and thermal performance before substitution.
