MAX4566CEE+T

Analog Switches - Special Purpose Overview

The MAX4566CEE+T is a dual, low-voltage, bidirectional RF/Video Switch IC manufactured by Analog Devices Inc./Maxim Integrated. It contains two dual SPST switches (one normally open, one normally closed) in a T-switch configuration. 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, and off isolation of -82dB at 10MHz. The component supports an operating temperature range of 0°C to +70°C and is housed in a 16-pin QSOP package.

Analog Switches - Special Purpose Feature Summary

• Bidirectional signal switching capability for RF and video applications
• T-switch architecture ensuring high-frequency off isolation and low crosstalk
• Compatible with TTL and CMOS logic inputs using single +5V or ±5V supplies
• Low power consumption with rail-to-rail analog signal handling

Analog Switches - Special Purpose Applications

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

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'CEE+T' against official documentation to confirm the commercial temperature range (0°C to +70°C) and QSOP-16 surface-mount packaging. Ensure compatibility with required supply voltages and logic thresholds before integration. Cross-reference manufacturer part numbers to avoid confusion with similar models like MAX4565 or MAX4567 which have different switch configurations.

Analog Switches - Special Purpose Selection Notes

Select this component when dual SPST switching with distinct normally open and normally closed paths is required. The T-switch design offers superior isolation compared to standard CMOS switches. Consider the 60Ω max on-resistance and 350MHz bandwidth limits for high-frequency signal integrity. Verify that the single-supply operation constraints do not clip negative voltage swings if used in AC-coupled applications.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4565/MAX4566/MAX4567 family of quad/dual low-voltage bidirectional RF/video switches. While the MAX4565 features four SPST switches and the MAX4567 features two SPDT switches, the MAX4566 specifically provides two dual SPST switches. All members share the same core T-switch technology and pinout compatibility within their respective package types.

Analog Switches - Special Purpose FAQ

What is the difference between the MAX4566 and MAX4567 switch configurations?

The MAX4566 contains two dual SPST switches (one normally open, one normally closed), whereas the MAX4567 contains two single-pole/double-throw (SPDT) switches.

How does the T-switch configuration improve performance?

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

Can the MAX4566 operate with a single supply?

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