MAX4565CWP+

Analog Switches - Special Purpose Overview

The MAX4565CWP+ is a quad, low-voltage bidirectional RF/video switch in a 20-pin Wide SOIC package. It contains four normally open single-pole/single-throw (SPST) switches with a -3dB bandwidth of 350MHz. The device operates from dual 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, an off-isolation of -83dB at 10MHz, and a crosstalk of -87dB at 10MHz. It features TTL/CMOS-compatible logic inputs and provides 2kV ESD protection per Method 3015.7.

Analog Switches - Special Purpose Feature Summary

• High-frequency T-switch architecture ensures superior isolation and minimal crosstalk for RF and video signals.
• Bidirectional signal paths support rail-to-rail analog signals in either direction across the specified voltage range.
• TTL and CMOS logic compatibility allows direct interfacing with standard digital control circuits.

Analog Switches - Special Purpose Applications

• RF switching in communication systems
• Video signal routing and distribution
• High-speed data acquisition systems
• Automated test equipment (ATE)
• Networking hardware

Analog Switches - Special Purpose Procurement Notes

Verify the component designation matches the specific datasheet revision and manufacturer documentation. Confirm that the ordering suffix corresponds to the required temperature range and packaging format. Ensure compliance with relevant environmental standards before integration into final designs.

Analog Switches - Special Purpose Selection Notes

Select this component when high-frequency performance up to 350MHz is required for SPST switching applications. Consider the ±5V optimized operation for best linearity and speed. Evaluate board layout requirements carefully to maintain ground plane integrity for optimal high-frequency characteristics.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4565/MAX4566/MAX4567 family of low-voltage analog switches. While the MAX4565 provides four SPST switches, the MAX4566 offers two dual SPST configurations, and the MAX4567 provides two SPDT switches. All share similar electrical characteristics and pinout structures within their respective packages.

Analog Switches - Special Purpose Replacement Considerations

Direct functional substitutes within the same family include the MAX4566 and MAX4567, which offer different switch configurations but identical electrical performance profiles. Verify pin compatibility and package dimensions when substituting.
