MAX4565EAP

Analog Switches - Special Purpose Overview

The MAX4565EAP is a quad, low-voltage, bidirectional RF/video switch manufactured by Analog Devices Inc. It contains four normally open single-pole/single-throw (SPST) switches designed for switching signals from DC to 350MHz in 50Ω and 75Ω systems. The device operates with 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, signal-path matching of 2.5Ω max, and flatness of 2Ω max. Off isolation is -83dB at 10MHz, with crosstalk of -87dB at 10MHz. The E suffix indicates an extended temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• High-frequency T-switch construction ensures excellent off isolation and crosstalk performance
• Bidirectional analog signal handling with rail-to-rail capability
• TTL and CMOS logic compatibility with defined input thresholds
• Low power consumption with minimal supply current draw

Analog Switches - Special Purpose Applications

• RF Signal Switching
• Video Signal Routing
• High-Speed Data Acquisition Systems
• Automated Test Equipment (ATE)
• Networking Infrastructure

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix 'E' confirms the -40°C to +85°C operating temperature range. Confirm the 'AP' package designation corresponds to the 20-pin Wide SO format as listed in official documentation. Ensure the source document matches the manufacturer's current revision to avoid discrepancies in pin configurations or absolute maximum ratings.

Analog Switches - Special Purpose Selection Notes

Select the MAX4565 when four independent SPST switches are required. Choose this component over MAX4566 or MAX4567 if normally closed or SPDT functionality is not needed. Verify that the system impedance matches the 50Ω or 75Ω design targets for optimal bandwidth and insertion loss characteristics. Ensure supply voltages remain within the specified limits to maintain logic threshold compatibility.

Analog Switches - Special Purpose Part Context

The MAX4565 is part of the MAX4565/MAX4566/MAX4567 family of low-voltage CMOS analog switches. While the MAX4566 offers dual SPST switches with one normally closed channel, and the MAX4567 provides two SPDT switches, the MAX4565 specifically provides four normally open channels. All members share similar T-switch architecture and electrical performance profiles optimized for high-frequency applications.
