MAX4566CPE

Analog Switches - Special Purpose Overview

The MAX4566CPE is a dual, low-voltage, bidirectional RF/Video Switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features two SPST switches (one normally open, one normally closed) in a 16-pin Plastic DIP 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 typical off isolation of -82dB at 10MHz. Operating temperature range is 0°C to +70°C.

Analog Switches - Special Purpose Feature Summary

• Bidirectional signal switching capability for RF and video applications
• T-switch construction ensuring high-frequency off isolation and low crosstalk
• TTL and CMOS logic compatibility with integrated level translators

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 suffix CPE indicates the 16-pin Plastic DIP package and commercial temperature range. Confirm RoHS compliance status as datasheets may vary by production batch. Check current availability through authorized distributors since this part number may be subject to discontinuation notices.

Analog Switches - Special Purpose Selection Notes

Select the MAX4566CPE when a dual switch configuration with mixed NO/NC states is required in a through-hole package. Ensure the application supports the 0°C to +70°C operating range. Verify that the 60Ω on-resistance meets system requirements compared to lower-resistance alternatives like the MAX4546.

Analog Switches - Special Purpose Part Context

The MAX4566 is part of the MAX4565/MAX4566/MAX4567 family of quad/dual low-voltage switches. While the MAX4565 offers four SPST switches and the MAX4567 provides two SPDT switches, the MAX4566 specifically integrates one NO and one NC SPST switch within the same T-switch architecture.

Analog Switches - Special Purpose Replacement Considerations

Public confirmed substitutes include MAX4566EEE+T (surface mount, extended temp) and MAX4566CEE+T (surface mount, commercial temp). For pin-compatible replacements, verify package dimensions and thermal characteristics against the original DIP requirement.

Analog Switches - Special Purpose FAQ

What is the difference between the MAX4566 and MAX4567?

The MAX4566 contains two SPST switches (one normally open, one normally closed), whereas the MAX4567 contains two SPDT switches.

How does the T-switch architecture improve performance?

The T-switch uses series CMOS switches with a third N-channel switch shunting capacitively-coupled signals to ground when off, ensuring excellent high-frequency isolation and crosstalk rejection.

Can the MAX4566 operate with a single supply?

Yes, it can operate with a single supply between +2.7V and +12V by connecting the V- pin to ground, though characteristics are optimized for ±5V dual supplies.
