MAX4566CSE+T

Analog Switches - Special Purpose Overview

The MAX4566CSE+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 16-pin QSOP 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, and off isolation of -82dB at 10MHz. Turn-on time is typically 150ns and turn-off time is typically 100ns under ±5V conditions.

Analog Switches - Special Purpose Feature Summary

• Bidirectional signal switching capability for RF and video applications
• High-frequency T-switch construction ensuring superior off isolation and crosstalk performance
• Low on-resistance with excellent matching and flatness over the specified signal range
• TTL and CMOS logic input compatibility

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 'CSE' against official documentation to confirm the commercial temperature range (0°C to +70°C) and QSOP-16 package type. Ensure the '+T' designation aligns with reel packaging requirements. Cross-reference the manufacturer's current production status as product lines may undergo discontinuance notifications.

Analog Switches - Special Purpose Selection Notes

Select this component when dual-channel bidirectional switching with break-before-make timing is required. Verify that the system impedance matches the 50Ω or 75Ω design targets for optimal bandwidth and isolation. Confirm that the supply voltage range accommodates the desired analog signal swing without exceeding absolute maximum ratings.

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 offers four SPST switches and the MAX4567 provides two SPDT switches, the MAX4566 specifically integrates two dual SPST configurations, combining normally open and normally closed paths within a single package.

Analog Switches - Special Purpose Replacement Considerations

Public confirmed substitutes include MAX4565EUK+T and MAX4567EEE+T. Verify pinout compatibility and switch configuration differences before substitution.
